14.16.2.1.4.1 Initial conditions
|
A call is set up according to the generic call set up procedure with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0.
The SS transmits Standard Test Signal C1.
In addition to this wanted signal (C), the SS produces an independent, uncorrelated interfering signal (I).
This unwanted signal is random, continuous and GSM-modulated, and has no fixed relationship with the bit transitions of the wanted signal.
For the ACK/NACK BLER and the BCS BLER parts of the test case, a downlink TBF will be established.
For the USF BLER parts of the test case the Test Mode defined in GSM Rec. 4.14 (para 5.4) will be used for uplink TBF. If the MS is capable of both:
Mode (a) transmitting pseudo-random data sequence in RLC data blocks;
Mode (b) transmitting looped-back RLC data blocks;
then Mode (a) will be used.
If Mode (b) is used then the SS sends the pseudo-random data sequence specified for Mode (a) on the downlink for loopback on the uplink.

14.16.2.1.4.2 Procedure
|
a) The SS transmits packets using CS-1 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14.16-2, the SS calculates the Block error ratio. The SS resets both counters.
f) In the case of CS-1 the SS repeats step c) to e) with the fading conditions and hopping modes: TUhigh/FH, and RA/noFH and, if the MS does not support DARP phase 1 also with TUhigh/noFH fading condition.
In the case of CS-2 the SS repeats step c) to e) with the fading condition and hopping mode RA/no FH only.
In the case of CS-3 the SS repeats step c) to e) with the fading condition and hopping mode TUhigh/FH only.
In the case of CS-4 and the MS does not support DARP phase 1 the SS repeats step c) to e) with the fading condition and hopping modes: TUhigh/noFH.
g) The SS repeats the steps b) to f) for each of the coding schemes CS-2, CS-3 and CS-4.
h) The SS sets the fading function to TUhigh/noFH.
i) The SS sets the value of the USF/CS-1 such as to allocate the uplink to the MS, using a co-channel interference level of 1 dB above the level given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/CS-1 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14.16-2, the SS calculates the Block error ratio. The SS resets both counters.
l) The SS repeats steps i) to k) using USF/CS2 coding.

14.16.2.1a Co-channel rejection for packet channels – TIGHTER configuration
14.16.2.1a.1 Definition
The co-channel rejection is a measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of an unwanted modulated signal, both signals being at the nominal frequency of the receiver.
14.16.2.1a.2 Conformance requirement
For a MS indicating support for TIGHTER Capability (see 3GPP TS 24.008), the minimum input signal levels for which the reference performance shall be met are specified in table 1w, according to the propagation condition. The performance requirements for GSM 400 and GSM 700 systems are as for GSM 900 in table 1w, except that the GSM 400 MS speed is doubled from that of GSM 900, e.g. TU50 becomes TU100, and the GSM 700 MS speed is increased by a factor of 1.2, e.g. TU50 becomes TU60.
1. The block error rate (BLER) performance shall not exceed 10 % at co-channel interference ratios (C/Ic) exceeding those according to the table14.16.2.1a-1 as below.

If included in a PACKET MEASUREMENT REPORT message, the measured interference level, gCH, shall be mapped to a reported I_LEVEL as defined for RXLEV in subclause 8.1.4. If included in a PACKET DOWNLINK ACK/NACK or a PACKET RESOURCE REQUEST message, the measured interference level, gCH, shall be mapped to a reported I_LEVEL value between 0 and 15, relative to reported C value as follows:
I_LEVEL 0 = interference level is greater than C
I_LEVEL 1 = interference level is less than or equal to C and greater than C - 2 dB
I_LEVEL 2 = interference level is less than or equal to C - 2 dB and greater than C - 4 dB

14.16.3.7 Test Procedure
|
In addition to the wanted signal on PDTCH, the SS produces an uncorrelated co-channel interfering signal, GMSK modulated: the unwanted signal is sent during idle frames of PDTCH of the wanted signal, and has no fixed relationship with the bit transitions of the wanted signal.
This interfering signal is sent on the same nominal carrier frequency as the PACCH and PDTCH and at a level x dB above the level of the PDTCH and modulated with random data.
x is a random value in [1 dB; -29 dB] in steps of 2 dB, negative values of x meaning that the resulting interference level is below the level of the PDTCH.
For instance, for GSM 900 MS, the resulting interference level depends on the x random value as follows:
x

-73 dBm

-75 dBm
-3 dB
-77 dBm

-103 dBm
NOTE: Values of the reference sensitivity level for every frequencies are defined in “3GPP TS 05.05.
a) The SS establishes a downlink TBF and sends RLC data blocks.
b) The MS is polled every 12 RLC data block by setting the S/P bit.
c) The SS verifies that a correct I_level parameter is included in the Channel Quality report of at least every other two Packet Downlink Ack/Nack messages.
d) The SS verifies that the reported value of I_level is correct: the measured interference level is mapped to a reported I_LEVEL value between 0 and 15, relative to reported C value as follows (as stated in 3GPP TS 05.08, subclauses 10.3), level resulting from the value of x:

The accuracy of the interference measurement shall fulfil the requirement as defined in 3GPP TS 05.08, subclauses 8.1.2:
the R.M.S received signal level at the receiver input shall be measured by the MS and the BSS over the full range of ‑110 dBm to ‑48 dBm with an absolute accuracy of ± 4 dB from ‑110 dBm to ‑70 dBm under normal conditions and ± 6 dB over the full range under both normal and extreme conditions.
Thus, for GSM 900 MS, the resulting tolerance is ± 4 dB for every value of the x random variable.

14.18 EGPRS receiver tests
|
Statistical testing of receiver BLER performance
Error Definition
Block Error Ratio (BLER):
The Block Error Ratio is the ratio of blocks received in error to the total number of received blocks, where a block is defined as received in error if the error detection functions in the receiver, operating in accordance with 3GPP TS 05.03, indicate an error as the result of the Block Check Sequence (BCS).
For USF the Block Error Ratio is the ratio of incorrectly interpreted USF to the total number of received USF.
Test criteria
In the receiver tests for circuit switched channels, test error rates have been defined in order not to pass MS with a performance worse than the specification by 1 dB, with tests to be performed at the sensitivity and interference levels defined in 3GPP TS 05.05. For circuit switched channels 3GPP TS 05.05 defines the error rates at a fixed sensitivity or interference level.
For packet switched channels 3GPP TS 05.05 defines the receive or interference level at which a fixed Block Error Ratio is met. Therefore, for EGPRS the receiver is tested with a 1 dB offset in the receive level and the interference level.
If the error events can be assumed to be random independent variables, outputs of stationary random processes with identical Gaussian distributions, the previous figures suggest a number of events not lower than 200 in AWGN channel and not lower than 600 in a multipath environment.
For multipath propagation conditions the hypothesis of stationary random processes does not generally hold. In case of non frequency hopping operation mode, the radio channel may be assumed to change 10 times per wavelength of travelled distance and to be short term stationary in between. So, in this case, the required observation time for having good statistical properties should not be lower (with some rounding) than that reported in table 14.18-1.

14.18.1.4 Method of test
|
Initial conditions
NOTE 1: The BA list sent on the BCCH will indicate at least six surrounding cells with at least one near to each band edge. It is not necessary to generate any of these BCCHs but, if provided the signal strengths of BCCHs shall be in the range 15 dBVemf( ) to 35 dBVemf( ). Surrounding cell signal levels and cell reselection parameters are set so that the MS will not try a cell reselection.
NOTE 2: The ARFCN of any BCCH shall not be co-channel or on adjacent channels to the wanted traffic channel.
NOTE 3: When frequency hopping is used under static conditions, the traffic channel may fall on any of the ARFCNs defined in clause 6. When frequency hopping is used under non-static conditions any ARFCNs shall be chosen.
NOTE 4: The PSI1 message is included in the PACCH when the MS is in packet transfer mode. The PBCCH_CHANGE_MARK value in PSI1 is not changed. This, together with preventing cell reselection as per Note 1, ensures that the MS is highly unlikely to suspend the TBF (3GPP TS 04.60 subclause 5.5.1.4.2 Suspension of operation to receive system operation), and thus making the effect of TBF suspension statistically insignificant for the test result.
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched on an ARFCN in the Mid range. The power control parameter ALPHA (α) is set to 0. The SS shall transmit on the maximum number of receive timeslots. The SS commands the MS to transmit at maximum power.
Test procedure
For GMSK Modulation:
a) The SS transmits packets under static conditions, using MCS-4 coding at a level of 1 dB above the level given in conformance reference 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using MCS-4 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with MCS-4 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 5: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
d) Once the number of blocks transmitted with MCS-4 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels , the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using MCS-3 coding with RA/No FH, MCS-2 coding with HT/No FH and MCS-1 coding with TUhigh/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for MCS-4 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/MCS-1 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-1 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters
m) The SS repeats steps i) to l) under extreme test conditions using USF/MCS-1 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/MCS-1 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
For 8-PSK Modulation:
a) The SS transmits packets under static conditions, using MCS-8 coding at a level of 1 dB above the level given in conformance reference 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using MCS-8 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with MCS-8 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 6: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
d) Once the number of blocks transmitted with MCS-8 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels, the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using MCS-9 with static condition, MCS-7 with TUhigh/FH, MSC-6 with HT/No FH and MSC-5 with RA/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for MCS-8 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/MCS-5 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-5 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) under extreme test conditions using USF/MCS-5 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/MCS-5 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.

14.18.1.5 Test requirements
|
In step a) the Packet Downlink Ack/Nack as sent by the MS shall indicate every block transmitted by the SS with incorrect BCS as not acknowledged.
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
In step n) for both GMSK modulation and 8-PSK modulation the MS shall transmit no more than 25 times.
In the case when downlink power control is not used and the output power used on the transmitted blocks is not equal to (BCCH level – Pb) then the MS is not required to fulfil 3GPP TS 05.05 requirements for the first 25 blocks addressed to this MS (3GPP TS 05.08, subclause 10.2.2).

Performance is specified at 30% BLER for those cases identified with mark **.
NOTE 1: Ideal FH case assumes perfect decorrelation between bursts. This case may only be tested if such a decorrelation is ensured in the test. For TU50 (ideal FH), sufficient decorrelation may be achieved with 4 frequencies spaced over 5 MHz.
NOTE 2: PDTCH for DAS-x can not meet the reference performance for some propagation conditions (*).
NOTE 3: The requirements for the DCS 1800 & PCS 1900 Static propagation condition are the same as for the GSM 850 & GSM 900 Static propagation condition, the requirements for DCS 1800 & PCS 1900 TU50 (ideal FH) propagation conditions are the same as for the DCS 1800 & PCS 1900 TU50 (no FH) propagation condition, and the requirements for the DCS 1800 & PCS 1900 RA130 (no FH) propagation condition are the same as for the GSM 850 & GSM 900 RA250 (no FH) propagation condition.
NOTE 4: The requirements for USF/DAS-5 to 7 are the same as for USF/MCS-5 to 9.
3. The BLER shall not exceed the conformance requirements given in 1 and 2 under extreme conditions; 3GPP TS 45.005, subclause 6.2 and annex D subclauses D.2.1 and D.2.2.
4. The reference sensitivity performance specified above need not be met in the following cases:
For MS at the static channel, if the received level on either of the two adjacent timeslots to the wanted exceed the wanted timeslot by more than 20 dB.
For MS on a multislot configuration, if the received level on any of the timeslots belonging to the same multislot configuration as the wanted time slot, exceed the wanted time slot by more than 6 dB.
The interfering adjacent time slots shall be static with valid GSM signals in all cases.
3GPP TS 45.005, subclause 6.2.
5. For an MS allocated a USF on a PDCH with a random RF input or a valid PDCH signal with a random USF not equal to the allocated USF, the overall reception shall be such that the MS shall detect the allocated USF in less than 1 % of the radio blocks for 8-PSK modulated signals and [1 %] for 16-QAM and 32-QAM modulated signals. This requirement shall be met for all input levels up to -40 dBm for 8-PSK modulated signals, and up to [-40 dBm] for 16-QAM and 32-QAM modulated signals.
3GPP TS 45.005, subclause 6.4
3GPP TS 45.005 subclause 2:
For T-GSM 810 the requirements for GSM 900 shall apply, apart for those parameters for which a separate requirement exists.
14.18.1a.3 Test purpose
1. To verify that the MS sends a Packet Not Acknowledge in the Packet Downlink Ack/Nack in case of the Block Check Sequence indicating a Block Error.
2. To verify that the MS does not exceed conformance requirement 1 for PDTCH with different coding schemes and under different propagation conditions with an allowance for the statistical significance of the test.
3. To verify that the MS does not exceed conformance requirement 2 under HT propagation conditions with an allowance for the statistical significance of the test.
4. To verify that the MS does not exceed conformance requirement 3 under STATIC, TUhigh, HT and RA propagation conditions for the PDTCH, and under HT propagation conditions for the USF, with an allowance for the statistical significance of the test.
5. To verify that the MS meets the conformance requirements also 1 and 2 for the conditions allowed by conformance requirement 4, with an allowance for the statistical significance of the test.
6. To verify that the MS meets conformance requirement 5, with an allowance for the statistical significance of the test.
14.18.1a.4 Method of test
Initial conditions
NOTE 1: The BA list sent on the BCCH will indicate at least six surrounding cells with at least one near to each band edge. It is not necessary to generate any of these BCCHs but, if provided the signal strengths of BCCHs shall be in the range 15 dBVemf( ) to xx35 dBVemf( ). Surrounding cell signal levels and cell reselection parameters are set so that the MS will not try a cell reselection.
NOTE 2: The ARFCN of any BCCH shall not be co-channel or on adjacent channels to the wanted traffic channel.
NOTE 3: When frequency hopping is used under static conditions, the traffic channel may fall on any of the ARFCNs defined in clause 6. When frequency hopping is used under non-static conditions any ARFCNs shall be chosen.
NOTE 4: The PSI1 message is included in the PACCH when the MS is in packet transfer mode. The PBCCH_CHANGE_MARK value in PSI1 is not changed. This, together with preventing cell reselection as per Note 1, ensures that the MS is highly unlikely to suspend the TBF (3GPP TS 04.60 subclause 5.5.1.4.2 Suspension of operation to receive system operation), and thus making the effect of TBF suspension statistically insignificant for the test result.
For 8-PSK, 16-QAM and 32-QAM modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched on an ARFCN in the Mid range. The power control parameter ALPHA (α) is set to 0. The SS shall transmit on the maximum number of receive timeslots. The SS commands the MS to transmit at maximum power.
Test procedure
For 8-PSK Modulation:
a) The SS transmits packets under static conditions, using DAS-7 coding at a level of 1 dB above the level given in conformance requirement 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using DAS-7 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with DAS-7 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with DAS-7 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels, the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using DAS-6 with HT/No FH and DAS-5 with RA/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for DAS-7 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/DAS-5 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/ DAS-5 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) under extreme test conditions using DAS-7 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/DAS-5 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
For 16-QAM Modulation:
a) The SS transmits packets under static conditions, using DAS-9 coding at a level of 1 dB above the level given in conformance requirement 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using DAS-9 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with DAS-9 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with DAS-9 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels, the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using DAS-8 with HT/No FH and RA/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for DAS-9 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/DAS-8 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/ DAS-8 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) under extreme test conditions using DAS-9 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/DAS-8 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
For 32-QAM Modulation:
a) The SS transmits packets under static conditions, using DAS-12 coding at a level of 1 dB above the level given in conformance requirement 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using DAS-12 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with DAS-12 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with DAS-12 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels, the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using DAS-11 with HT/No FH and DAS-10 with RA/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for DAS-12 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/DAS-10 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/ DAS-10 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) under extreme test conditions using DAS-12 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/DAS-10 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
14.18.1a.5 Test requirements
In step a) the Packet Downlink Ack/Nack as sent by the MS shall indicate every block transmitted by the SS with incorrect BCS as not acknowledged.
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
In step n) for 8PSK, 16-QAM and 32-QAM modulation the MS shall transmit no more than 25 times.
In the case when downlink power control is not used and the output power used on the transmitted blocks is not equal to (BCCH level – Pb) then the MS is not required to fulfil 3GPP TS 45.005 requirements for the first 25 blocks addressed to this MS (3GPP TS 05.08, subclause 10.2.2).
14.18.1b Minimum Input level for Reference Performance in TIGHTER configuration
14.18.1b.1 Definition
The minimum input level is the signal level at the MS receiver input at which a certain BLER is met.
14.18.1b.2 Conformance requirement
For a MS indicating support for TIGHTER Capability (see 3GPP TS 24.008), the minimum input signal levels for which the reference performance shall be met are specified in table 1w, according to the propagation condition. The performance requirements for GSM 400 and GSM 700 systems are as for GSM 900 in table 1w, except that the GSM 400 MS speed is doubled from that of GSM 900, e.g. TU50 becomes TU100, and the GSM 700 MS speed is increased by a factor of 1.2, e.g. TU50 becomes TU60.
1. The block error rate (BLER) performance for PDTCH/MCS1 to 4 shall not exceed 10 % at input levels according to the table 14.18.1b-3a; and for PDTCH/MCS5 to 9 shall not exceed 10 % or 30 % depending on Coding Schemes at input levels according to the table 14.18.1b-3b.

14.18.1b.4 Method of test
Initial conditions
NOTE 1: The BA list sent on the BCCH will indicate at least six surrounding cells with at least one near to each band edge. It is not necessary to generate any of these BCCHs but, if provided the signal strengths of BCCHs shall be in the range 15 dBVemf( ) to 35 dBVemf( ). Surrounding cell signal levels and cell reselection parameters are set so that the MS will not try a cell reselection.
NOTE 2: The ARFCN of any BCCH shall not be co-channel or on adjacent channels to the wanted traffic channel.
NOTE 3: When frequency hopping is used under static conditions, the traffic channel may fall on any of the ARFCNs defined in clause 6. When frequency hopping is used under non-static conditions any ARFCNs shall be chosen.
NOTE 4: The PSI1 message is included in the PACCH when the MS is in packet transfer mode. The PBCCH_CHANGE_MARK value in PSI1 is not changed. This, together with preventing cell reselection as per Note 1, ensures that the MS is highly unlikely to suspend the TBF (3GPP TS 04.60 subclause 5.5.1.4.2 Suspension of operation to receive system operation), and thus making the effect of TBF suspension statistically insignificant for the test result.
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched on an ARFCN in the Mid range. The power control parameter ALPHA (α) is set to 0. The SS shall transmit on the maximum number of receive timeslots. The SS commands the MS to transmit at maximum power.
Test procedure
For GMSK Modulation:
a) The SS transmits packets under static conditions, using MCS-4 coding at a level of 1 dB above the level given in conformance reference 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using MCS-4 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with MCS-4 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 5: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
d) Once the number of blocks transmitted with MCS-4 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels , the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using MCS-3 coding with RA/No FH, MCS-2 coding with HT/No FH and MCS-1 coding with TUhigh/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for MCS-4 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/MCS-1 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-1 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters
m) The SS repeats steps i) to l) under extreme test conditions using MCS-1 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/MCS-1 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
For 8-PSK Modulation:
a) The SS transmits packets under static conditions, using MCS-8 coding at a level of 1 dB above the level given in conformance reference 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using MCS-8 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with MCS-8 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 6: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
d) Once the number of blocks transmitted with MCS-8 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels, the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using MCS-9 with static condition, MCS-7 with TUhigh/FH, MSC-6 with HT/No FH and MSC-5 with RA/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for MCS-8 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/MCS-5 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-5 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) under extreme test conditions using MCS-5 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/MCS-5 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
14.18.1b.5 Test requirements
In step a) the Packet Downlink Ack/Nack as sent by the MS shall indicate every block transmitted by the SS with incorrect BCS as not acknowledged.
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
In step n) for both GMSK modulation and 8-PSK modulation the MS shall transmit no more than 25 times.
In the case when downlink power control is not used and the output power used on the transmitted blocks is not equal to (BCCH level – Pb) then the MS is not required to fulfil 3GPP TS 45.005 requirements for the first 25 blocks addressed to this MS (3GPP TS 45.008, subclause 10.2.2).
14.18.1c Minimum Input level for Reference Performance – in TIGHTER configuration
14.18.1c.1 Definition
The minimum input level is the signal level at the MS receiver input at which a certain BLER is met.
14.18.1c.2 Conformance requirement
For a MS indicating support for TIGHTER Capability (see 3GPP TS 24.008), the minimum input signal levels for which the reference performance shall be met are specified in table 1w, according to the propagation condition. The performance requirements for GSM 400 and GSM 700 systems are as for GSM 900 in table 1w, except that the GSM 400 MS speed is doubled from that of GSM 900, e.g. TU50 becomes TU100, and the GSM 700 MS speed is increased by a factor of 1.2, e.g. TU50 becomes TU60.
1. The block error rate (BLER) performance for PDTCH/MCS1 to 4 shall not exceed 10 % at input levels according to the table 14.18.1c-1; and for PDTCH/MCS5 to 9 shall not exceed 10 % or 30 % depending on Coding Schemes at input levels according to the table 14.18.1c-1.

Surrounding cell signal levels and cell reselection parameters are set so that the MS will not try a cell reselection.
NOTE 2: The ARFCN of any BCCH shall not be co-channel or on adjacent channels to the wanted traffic channel.
NOTE 3: When frequency hopping is used under static conditions, the traffic channel may fall on any of the ARFCNs defined in clause 6. When frequency hopping is used under non-static conditions any ARFCNs shall be chosen.

Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using MCS-4 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with MCS-4 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 5: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
d) Once the number of blocks transmitted with MCS-4 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels , the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using MCS-3 coding with RA/No FH, MCS-2 coding with HT/No FH and MCS-1 coding with TUhigh/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for MCS-4 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/MCS-1 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-1 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters
m) The SS repeats steps i) to l) under extreme test conditions using MCS-4 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/MCS-1 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
For 8-PSK Modulation:
a) The SS transmits packets under static conditions, using MCS-8 coding at a level of 1 dB above the level given in conformance reference 1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS Packet Downlink Ack/Nack as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using MCS-8 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in the table in conformance requirement 1. On the time slots not allocated to the MS, the SS transmits at a level of 20 dB above the level given in the table in conformance requirement 1. This implicitly tests adjacent time slot rejection.
c) The SS counts the number of blocks transmitted with MCS-8 and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 6: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can sent this message.
d) Once the number of blocks transmitted with MCS-8 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TUhigh/noFH and TUhigh/FH. For these tests with fading channels, the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using MCS-9 with static condition, MCS-7 with TUhigh/FH, MSC-6 with HT/No FH and MSC-5 with RA/No FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for MCS-8 coding only.
h) This step is only performed for a multislot MS. The SS establishes the normal test conditions with the exceptions in the parameter settings of Packet Downlink Assignment message:
• P0 = 14 dB;
• BTS_PWR_CTRL_MODE = Mode A;
• PR_MODE = B.
Furthermore, the SS has to set the PR fields in the MAC headers of each downlink RLC data block to correspond the applied downlink power level, as defined below. The SS repeats steps b) to d) with only one of the active timeslots at 1 dB above the level at which the reference sensitivity performance shall be met, and all other timeslots belonging to the same multislot configuration at a level of 6 dB above this timeslot.
i) The SS establishes the normal test conditions, and sets the fading function to HT/noFH. An uplink TBF shall be established.
j) The SS sets the value of the USF/MCS-5 such as to allocate the uplink to the MS, transmitting at a level of 1 dB above the level given in the table in conformance requirement 2.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-5 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) under extreme test conditions using MCS-9 coding.
n) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/MCS-5 to all values randomly, with the exception of the one allocated to the MS, transmitting at 3 dB below the level at which reference performance shall be met, and counts the number of times the MS transmits on the uplink. This is done for 2 000 blocks.
14.18.1c.5 Test requirements
In step a) the Packet Downlink Ack/Nack as sent by the MS shall indicate every block transmitted by the SS with incorrect BCS as not acknowledged.
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
In step n) for both GMSK modulation and 8-PSK modulation the MS shall transmit no more than 25 times.
In the case when downlink power control is not used and the output power used on the transmitted blocks is not equal to (BCCH level – Pb) then the MS is not required to fulfil 3GPP TS 45.005 requirements for the first 25 blocks addressed to this MS (3GPP TS 05.008, subclause 10.2.2).

14.18.1d.4 Method of test
Initial conditions
NOTE 1: The BA list sent on the EC-BCCH will indicate at least six surrounding cells with at least one near to each band edge. It is not necessary to generate any of these BCCHs but, if provided the signal strengths of BCCHs shall be in the range 15 dBVemf( ) to 35 dBVemf( ). Surrounding cell signal levels and cell reselection parameters are set so that the MS will not try a cell reselection.
NOTE 2: The ARFCN of any BCCH shall not be co-channel or on adjacent channels to the wanted traffic channel.
NOTE 3: When frequency hopping is used under static conditions, the traffic channel may fall on any of the ARFCNs defined in clause 6. When frequency hopping is used under non-static conditions any ARFCNs shall be chosen.
A downlink EC TBF is set up according to the generic procedure specified in clause 40 for packet switched on an ARFCN in the Mid range. The power control parameter ALPHA (α) is set to 0. The SS shall transmit on the maximum number of receive timeslots. The SS commands the MS to transmit at maximum power.
Test procedure
For GMSK Modulation:
a) The SS transmits packets under static conditions, using EC-PDTCH/MCS-1 coding at a level of 1 dB above the level given in table14.18.1d-1. Out of the 400 blocks transmitted by the SS, 20 blocks are sent with incorrect BCS, at (pseudo) random positions. The SS checks, for the blocks it transmitted with incorrect BCS, whether or not the MS EC Packet Downlink Ack/Nack, see TS 44.018 sub-clause 11.2.51, as sent by the MS indicates these blocks as not acknowledged.
b) The SS transmits packets under static conditions, with the MS commanded to hopping mode using the hopping sequence used in clause 6, and using EC-PDTCH/MCS-1 coding to the MS on all allocated timeslots, at a level of 1 dB above the level given in table 14.18.1d-1.
c) The SS counts the number of blocks transmitted with EC-PDTCH/MCS-1 and the number of these blocks not acknowledged based on the content of the EC Packet Downlink Ack/Nack Description information element (see 3GPP TS 44.060, subclause 11.2.51) in the EC Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
d) Once the number of blocks transmitted with EC-PDTCH/MCS-1 as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats step b) to d) with the following two fading conditions and hopping modes: TU1.2/noFH and TU1.2/FH in case ideal decorrelation can be ensured between the burst. For these tests with fading channels , the SS does not transmit on the timeslots not allocated to the MS.
f) The SS repeats steps b) to d) using EC-PDTCH/MCS-1/16 CC4 coding with TU1.2/No FH, EC-PDTCH/MCS-1/8 CC2 coding with TU50/No FH, EC-PDTCH/MCS-1/8 CC2 coding with TU1.2 No FH and EC-PDTCH/MCS-1/4 CC3 coding with TU1.2/FH. For these tests, the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to e) under extreme test conditions for EC-PDTCH/MCS-1 coding only.
14.18.1d.5 Test requirements
In step a) the Packet Downlink Ack/Nack as sent by the MS shall indicate every block transmitted by the SS with incorrect BCS as not acknowledged.
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
In the case when downlink power control is not used and the output power used on the transmitted blocks is not equal to (BCCH level – Pb) then the MS is not required to fulfil 3GPP TS 45.005 requirements for the first 25 blocks addressed to this MS (3GPP TS 45.008, subclause 10.2.2).

Initial conditions
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0.
The SS transmits EGPRS RLC data blocks containing random data. In addition to these data blocks, the SS produces an independent, uncorrelated interfering signal (I1).
Specific PICS statements:
- Support of DARP Phase 1 (TSPC_DARP_Phase1)
PIXIT Statements:

Test procedure
For GMSK Modulation:
a) The SS transmits packets on PDTCH using MCS-4 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) If the MS does not support DARP phase 1 the SS repeats step c) to e) with the TUhigh/noFH fading condition
g) The SS repeats the steps c) to e) for the coding schemes, MCS-2 with TUhigh/FH and for MCS-1 with RA/noFH and, if the MS does not support DARP phase 1, also the coding scheme MCS-3 with TUhigh/noFH.
h) The SS establishes the normal test conditions, and sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
i) The SS sets the value of the USF/MCS-4 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/MCS-4 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using MCS-8 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats step c) to e) with the TUhigh/noFH fading condition.
g) The SS repeats steps c) to e) for MCS-9 with TUlow/NoFH, MCS-7 with TUhigh/noFH, MCS-6 with TUhigh/FH and MSC-5 with RA/noFH.
h) The SS sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
i) The SS sets the value of the USF/MCS-9 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/MCS-9 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.

14.18.2a Co-channel rejection in EGPRS2A
14.18.2a.1 Definition
The co-channel rejection is a measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of an unwanted modulated signal, both signals being at the nominal frequency of the receiver. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
14.18.2a.2 Conformance requirement
1. The block error rate (BLER) performance for PDTCH/DAS 5 to 7 shall not exceed 10 % at input levels according to the table 14.18-5c; and for PDTCH/DAS 8 to 9 shall not exceed 10 % or 30 % depending on Coding Schemes at input levels according to the table 14.18-5d; and for PDTCH/DAS 10 to 12 shall not exceed 10 % or 30 % depending on Coding Schemes at input levels according to the table 14.18-5e.

14.18.2a.3 Test purpose
1. To verify that the MS does not exceed conformance requirement 1 for different coding schemes and under different propagation conditions with an allowance for the statistical significance of the test.
2. To verify that the MS does not exceed conformance requirement 2 under propagation condition TUhigh/noFH, with an allowance for the statistical significance of the test.
14.18.2a.4 Method of test
Initial conditions
For 8-PSK, 16QAM, and 32 QAM modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0.
The SS transmits EGPRS RLC data blocks containing random data. In addition to these data blocks, the SS produces an independent, uncorrelated interfering signal (I1).
Specific PICS statements:
-
PIXIT Statements:

Test procedure
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using DAS-7 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats step c) to e) with the TUhigh/noFH fading condition.
g) The SS repeats steps c) to e) for, DAS-6 with TUhigh/FH and DAS-5 with RA/noFH.
h) The SS sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
i) The SS sets the value of the USF/DAS-7 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/DAS-7 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
For 16-QAM Modulation:
a) The SS transmits packets on PDTCH using DAS-9 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats step c) to e) with the TUhigh/noFH fading condition.
g) The SS repeats steps c) to e) for, DAS-8 with TUhigh/FH
h) The SS sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
i) The SS sets the value of the USF/DAS-9 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/DAS-9 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
For 32-QAM Modulation:
a) The SS transmits packets on PDTCH using DAS-12 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats step c) to e) with the TUhigh/noFH fading condition.
g) The SS repeats steps c) to e) for, DAS-11 with TUhigh/FH and DAS-10 with RA/noFH.
h) The SS sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
i) The SS sets the value of the USF/DAS-12 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/DAS-12 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
14.18.2a.5 Test requirements
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, shall not exceed the conformance requirement.
14.18.2b Co-channel rejection – in TIGHTER configuration

14.18.2b.4 Method of test
Initial conditions
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0.
The SS transmits EGPRS RLC data blocks containing random data. In addition to these data blocks, the SS produces an independent, uncorrelated interfering signal (I1).

Test procedure
For GMSK Modulation:
a) The SS transmits packets on PDTCH using MCS-4 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 440.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats the steps c) to e) for the coding schemes, MCS-2 with TUhigh/FH and for MCS-1 with RA/noFH.
g) The SS establishes the normal test conditions, and sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
h) The SS sets the value of the USF/MCS-4 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
i) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
j) Once the number of USF/MCS-4 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using MCS-8 coding to the MS on all allocated timeslots.
b) The fading characteristic of the wanted signal and the interfering signal is TUlow, no FH applies.
c) The co-channel interference ratio is set to 1 dB above the ratio given in the table in conformance requirement 1. The interferer shall have the same frequency hopping sequence as the wanted signal, as well as be subject to the same fading profile.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats step c) to e) with the TUhigh/noFH fading condition.
g) The SS repeats steps c) to e) for MCS-9 with TUlow/NoFH, MCS-7 with TUhigh/noFH, MCS-6 with TUhigh/FH and MSC-5 with RA/noFH.
h) The SS sets the fading function to TUhigh/noFH. An uplink TBF shall be established.
i) The SS sets the value of the USF/MCS-9 such as to allocate the uplink to the MS, using a co-channel interference ratio of 1 dB above the ratio given in the table in conformance requirement 2.
j) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
k) Once the number of USF/MCS-9 allocating the uplink for the MS as counted in step j) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
14.18.2b.5 Test requirements
The block error ratio, as calculated by the SS for different channels and under the different propagation conditions, shall not exceed the conformance requirement.
14.18.2c Co-channel rejection in EGPRS2A with TIGHTER configuration
14.18.2c.1 Definition
The co-channel rejection is a measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of an unwanted modulated signal with additional TIGHTER requirements, both signals being at the nominal frequency of the receiver. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
14.18.2c.2 Conformance requirement
1. The block error rate (BLER) performance for PDTCH/DAS 5 to 7 shall not exceed 10 % at input levels according to the table 14.18-5c; and for PDTCH/DAS 8 to 9 shall not exceed 10 % or 30 % depending on Coding Schemes at input levels according to the table 14.18-5d; and for PDTCH/DAS 10 to 12 shall not exceed 10 % or 30 % depending on Coding Schemes at input levels according to the table 14.18-5e.

14.18.3.1 Definition
|
The adjacent channel selectivity is a measure of the capability of the receiver to receive wanted data packets without exceeding a given degradation due to the presence of an interfering signal (I1) in the adjacent channel. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
The adjacent channel can be the adjacent in the RF spectrum or in time. There are therefore two types of adjacent channel selectivity:
1) Adjacent RF channel selectivity which is specifically tested in this subclause.
2) Adjacent Time Slot selectivity, which is implicitly tested in test 14.18.2.

Initial conditions
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0. The SS transmits EGPRS RLC data blocks containing random data. In addition to the wanted test signal, the SS transmits an independent, uncorrelated interfering signal Standard Test Signal (I1). This unwanted signal is random, continuous and GMSK-modulated, and has no fixed relationship with the bit transitions of the wanted signal.
The fading characteristic of the wanted and the interfering signal is TUhigh/noFH
Test procedure
For GMSK Modulation:
a) The SS transmits packets on PDTCH using MCS-1 coding to the MS on all allocated timeslots.
b) The SS transmits the unwanted signal at a nominal frequency 200kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
c) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with the current coding scheme as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
f) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
g) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
h) The SS repeats steps b) to g) for each of the coding schemes MCS-2 to 4.
i) The SS repeats steps a) to g) under extreme test conditions for MCS-4 coding scheme only.
j) The SS establishes the normal test conditions. An uplink TBF shall be established.
k) The SS sets the value of the USF/MCS-1 such as to allocate the uplink to the MS.
l) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
m) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
n) Once the number of USF/MCS-1 allocating the uplink for the MS as counted in step m) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.
o) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set at to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
p) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
q) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 400 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
r) The SS repeats steps k) to q) under extreme test conditions for coding scheme USF/MCS-4.
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using MCS-5 coding to the MS on all allocated timeslots.
b) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
c) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with the current coding scheme as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.

14.18.3a Adjacent channel rejection in EGPRS2A configuration
14.18.3a.1 Definition
The adjacent channel selectivity is a measure of the capability of the receiver to receive wanted data packets without exceeding a given degradation due to the presence of an interfering signal (I1) in the adjacent channel. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
The adjacent channel can be the adjacent in the RF spectrum or in time. There are therefore two types of adjacent channel selectivity:
1) Adjacent RF channel selectivity which is specifically tested in this subclause.
2) Adjacent Time Slot selectivity, which is implicitly tested in test 14.18.2.

14.18.3a.4 Method of test
Initial conditions
For both 8-PSK, 16-QAM and 32-QAM modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0. The SS transmits EGPRS RLC data blocks containing random data. In addition to the wanted test signal, the SS transmits an independent, uncorrelated interfering signal Standard Test Signal (I1). This unwanted signal is random, continuous and GMSK-modulated, and has no fixed relationship with the bit transitions of the wanted signal.
The fading characteristic of the wanted and the interfering signal is TUhigh/noFH
Test procedure
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using DAS-5 coding to the MS on all allocated timeslots.
b) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
c) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 44.060, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with the current coding scheme as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
f) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.

i) The SS repeats steps a) to h) under extreme test conditions for coding scheme DAS-6 only.
j) The SS establishes the normal test conditions. An uplink TBF shall be established.

l) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
m) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
n) Once the number of USF/DAS-5 allocating the uplink for the MS as counted in step m) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.

14.18.3a.5 Test requirements
The block error ratio, as calculated by the SS for different channels with different coding schemes and under TUhigh propagation condition, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
Testing of the conformance requirement for USF/DAS (5-12)can be done either with fixed minimum number of samples or based on the statistical test method that lead to an early pass/fail decision with test time significantly reduced for MS with BLER not on the limit.
14.18.3a.5.1 Fixed limit test with minimum number of samples
The fixed testing of the conformance requirement is done using the minimum number of samples and the limit BLER given in table 14.18‑2.
14.18.3a.5.2 Statistical test with early pass / fail decision
Specific details on statistical testing of BER/BLER performance are defined in Annex 7.
Minimum test time due to fading conditions has to be considered before checking the conformance limits. The minimum test time for the specific fading condition are specified in the table 14.18.3a.5-1.

14.18.3b Adjacent channel rejection for packet channels in TIGHTER configuration
14.18.3b.1 Definition
The adjacent channel selectivity is a measure of the capability of the receiver to receive wanted data packets without exceeding a given degradation due to the presence of an interfering signal (I1) in the adjacent channel. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
The adjacent channel can be the adjacent in the RF spectrum or in time. There are therefore two types of adjacent channel selectivity:
1) Adjacent RF channel selectivity which is specifically tested in this subclause.
2) Adjacent Time Slot selectivity, which is implicitly tested in test 14.18.2.
14.18.3b.2 Conformance requirement
For a MS indicating support for TIGHTER Capability (see 3GPP TS 24.008), the requirements for adjacent channel performance for packet switched channels in the tables 2g, 2i, 2l, 2n, 2w and 2af, are also valid for GSM 400 with the exception that MS speed is doubled, e.g. TU50 becomes TU100. For GSM 700 the values in tables 2g, 2i, 2l, 2n, 2v, 2w and 2af, are valid with the exception that GSM 700 MS speed is increased by a factor of 1.2, e.g. TU50 becomes TU60. the requirements for adjacent channel performance for packet switched channels in table 2y and 2af are also valid for GSM 400 with the exception that MS speed is doubled, e.g. TU50 becomes TU100. For GSM 700 the values in table 2y and 2af are valid with the exception that GSM 700 MS speed is increased by a factor of 1.2, e.g. TU50 becomes TU60.
1. For GMSK modulation, under adjacent channel interference at 200 kHz above and below the wanted signal frequency and at the adjacent interference ratio (C/Ia1) specified in table 14.18.3b-1.

14.18.3b.4 Method of test
Initial conditions
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0. The SS transmits EGPRS RLC data blocks containing random data. In addition to the wanted test signal, the SS transmits an independent, uncorrelated interfering signal Standard Test Signal (I1). This unwanted signal is random, continuous and GMSK-modulated, and has no fixed relationship with the bit transitions of the wanted signal.
The fading characteristic of the wanted and the interfering signal is TUhigh/noFH
Test procedure
For GMSK Modulation:
a) The SS transmits packets on PDTCH using MCS-1 coding to the MS on all allocated timeslots.
b) The SS transmits the unwanted signal at a nominal frequency 200kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
c) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with the current coding scheme as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
f) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
g) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
h) The SS repeats steps b) to g) for each of the coding schemes MCS-2 to 4.
i) The SS repeats steps a) to g) under extreme test conditions for MCS-4 coding scheme only.
j) The SS establishes the normal test conditions. An uplink TBF shall be established.
k) The SS sets the value of the USF/MCS-1 such as to allocate the uplink to the MS.
l) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
m) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
n) Once the number of USF/MCS-1 allocating the uplink for the MS as counted in step m) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.
o) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set at to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
p) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
q) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 400 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
r) The SS repeats steps k) to q) under extreme test conditions for coding scheme USF/MCS-4.
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using MCS-5 coding to the MS on all allocated timeslots.
b) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
c) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
d) Once the number of blocks transmitted with the current coding scheme as counted in step c) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
e) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
f) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
g) The SS repeats steps c) and d) with the unwanted signal transmitted at a nominal frequency 400 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
h) The SS repeats steps b) to g) for each of the coding schemes MCS-6 to 8 and for the coding scheme MCS-9 with the TU low fading condition for both the wanted and the interfering signal.
i) The SS repeats steps a) to h) under extreme test conditions for coding scheme MCS-9 only.
j) The SS establishes the normal test conditions. An uplink TBF shall be established.
k) The SS sets the value of the USF/MCS-5 such as to allocate the uplink to the MS.
l) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
m) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
n) Once the number of USF/MCS-5 allocating the uplink for the MS as counted in step m) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
o) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 200 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
p) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 400 kHz above the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.
q) The SS repeats steps m) and n) with the unwanted signal transmitted at a nominal frequency 400 kHz below the nominal frequency of the wanted signal and its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.

14.18.3b.5 Test requirements
The block error ratio, as calculated by the SS for different channels with different coding schemes and under TUhigh propagation condition, under any combination of normal and extreme test voltages and ambient temperatures, shall not exceed the conformance requirement.
Testing of the conformance requirement for USF/MCS (1-9 )can be done either with fixed minimum number of samples or based on the statistical test method that lead to an early pass/fail decision with test time significantly reduced for MS with BLER not on the limit.
14.18.3b.5.1 Fixed limit test with minimum number of samples
The fixed testing of the conformance requirement is done using the minimum number of samples and the limit BLER given in table 14.18-2.
14.18.3b.5.2 Statistical test with early pass / fail decision
Specific details on statistical testing of BER/BLER performance are defined in Annex 7.
Minimum test time due to fading conditions has to be considered before checking the conformance limits. The minimum test time for the specific fading condition are specified in the table 14.18.3b-3.

14.18.3c Adjacent channel rejection in EGPRS2A configuration with TIGHTER configuration
14.18.3c.1 Definition
The adjacent channel selectivity is a measure of the capability of the receiver to receive wanted data packets without exceeding a given degradation due to the presence of an interfering signal (I1) in the adjacent channel. "Wanted signal" with additional TIGHTER requirements in this test is the signal generated by the transmitted RLC data blocks.
The adjacent channel can be the adjacent in the RF spectrum or in time. There are therefore two types of adjacent channel selectivity:
1) Adjacent RF channel selectivity which is specifically tested in this subclause.
2) Adjacent Time Slot selectivity, which is implicitly tested in test 14.18.2.

14.18.3c.4 Method of test
Initial conditions
For both 8-PSK, 16-QAM and 32-QAM modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0. The SS transmits EGPRS RLC data blocks containing random data. In addition to the wanted test signal, the SS transmits an independent, uncorrelated interfering signal Standard Test Signal (I1). This unwanted signal is random, continuous and GMSK-modulated, and has no fixed relationship with the bit transitions of the wanted signal.
The fading characteristic of the wanted and the interfering signal is TUhigh/noFH
Test procedure
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using DAS-5 coding to the MS on all allocated timeslots.
b) The SS transmits the unwanted signal at a nominal frequency 200 kHz above the nominal frequency of the wanted signal. Its amplitude is set to achieve the adjacent interference ratio 1dB above that specified in the conformance requirements.

NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.

14.18.3d Adjacent channel rejection in DLMC configuration
14.18.3d.1 Definition
The adjacent channel selectivity is a measure of the capability of the receiver to receive wanted data packets without exceeding a given degradation due to the presence of an interfering signal (I1) in the adjacent channel. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
The adjacent channel can be the adjacent in the RF spectrum or in time. There are therefore two types of adjacent channel selectivity:
1) Adjacent RF channel selectivity which is specifically tested in this subclause.
2) Adjacent Time Slot selectivity, which is implicitly tested in test 14.18.2.

14.18.3e Adjacent channel rejection in EC-GSM-IoT Configuration
14.18.3e.1 Definition
The adjacent channel selectivity is a measure of the capability of the receiver to receive wanted data packets without exceeding a given degradation due to the presence of an interfering signal (I1) in the adjacent channel. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
The adjacent channel can be the adjacent in the RF spectrum or in time. There are therefore two types of adjacent channel selectivity:
1) Adjacent RF channel selectivity which is specifically tested in this subclause.
2) Adjacent Time Slot selectivity, which is implicitly tested in test 14.18.2.
14.18.3e.2 Conformance requirement
1. For GMSK modulation, under adjacent channel interference at 200 kHz above and below the wanted signal frequency and at the adjacent interference ratio (C/Ia1) specified in table 14.18.3e.2-1.

1.2 For a TU1.2 faded wanted signal and a RA250 in case low band (or RA130 for high band) adjacent channel interferer, The block error rate (BLER) performance for EC-CCCH/D/32 (EC-PCH) shall not exceed 10 %; 3GPP TS 45.005, subclause 6.2.
1.3 For a TU1.2 faded wanted signal and a RA250 in case low band (or RA130 for high band) adjacent channel interferer, The block error rate (BLER) performance for EC-PACCH/D/16 shall not exceed 10 %; 3GPP TS 45.005, subclause 6.2.

14.18.3e.4 Method of test
Initial conditions
For GMSK, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the mid ARFCN range, power control level set to maximum power. The power control parameter ALPHA (α) is set to 0. The SS transmits EGPRS RLC data blocks containing random data. In addition to the wanted test signal, the SS transmits an independent, uncorrelated interfering signal Standard Test Signal (I1). This unwanted signal is random, continuous and GMSK-modulated, and has no fixed relationship with the bit transitions of the wanted signal.
The fading characteristic of the wanted signal is TU1.2/noFH and RA250/noFH in low band (or RA130/noFH for high band) for the interfering signal.

14.18.4.4 Method of test
|
NOTE: The measurements address the third order intermodulation, which represents the most serious case.
Initial conditions
For both GMSK and 8-PSK modulations, a downlink TBF is set up according to the generic procedure specified in clause 40 for packet switched with an ARFCN in the Mid ARFCN range, power control level set to maximum. The power control parameter ALPHA (α) is set to 0.
The SS transmits EGPRS RLC data blocks containing random data. The amplitude of the wanted signal is set to 4 dB above the reference sensitivity level with appropriate correction value as specified in table 14.18-3a for GMSK modulation and table 14.18-3b for 8-PSK modulation for PDTCH channel and in tables 14.18-4a for GMSK modulation and 14.18-4b for 8-PSK modulation for USF channel.
In addition to the static wanted test signal, the SS transmits two static interfering (unwanted) signals at the same time. There is no correlation in the modulation between the signals.
Test procedure
For GMSK modulation:
a) The SS transmits packets on PDTCH using MCS-4 coding to the MS on all allocated timeslots.
b) The first interfering signal is on a frequency equal to the centre frequency of an ARFCN four above the ARFCN of the wanted signal. This signal is static, continuous and unmodulated.
c) The second interfering signal is on an ARFCN eight above the ARFCN of the wanted signal. This signal is static, continuous and GMSK modulated by random data (I1).
The amplitude of both the interfering signals is set according to table 14.18-8.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats steps d) and e) with the two unwanted signals having frequencies corresponding to ARFCN four and eight below the ARFCN of the wanted signal.
g) The SS repeats steps a) to f) with the receiver operating on an ARFCN in the Low ARFCN.
h) The SS repeats steps a) to f) with the receiver operating on an ARFCN in the High ARFCN range.
i) The SS repeats steps a) to f) for each of the coding schemes MCS-1 to 3.
j) Steps a) to h) are repeated under extreme test conditions for MCS-4 only.

n) The second interfering signal is on an ARFCN eight above the ARFCN of the wanted signal. This signal is static, continuous and GMSK modulated by random data (I1).
The amplitude of both the interfering signals is set according to table 14.18-8.
o) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
p) Once the number of USF/MCS-4 allocating the uplink for the MS as counted in step o) reaches or exceeds the minimum number of blocks as given in table 14-18-2, the SS calculates the Block error ratio. The SS resets both counters.
q) The SS repeats steps o) and p) with the two unwanted signals having frequencies corresponding to ARFCN four and eight below the ARFCN of the wanted signal.
r) The SS repeats steps l) to q) with the receiver operating on an ARFCN in the Low ARFCN.
s) The SS repeats steps l) to q) with the receiver operating on an ARFCN in the High ARFCN range.
t) The SS repeats steps l) to s) under extreme test conditions for MCS-4.
For 8-PSK Modulation:
a) The SS transmits packets on PDTCH using MCS-9 coding to the MS on all allocated timeslots.
b) The first interfering signal is on a frequency equal to the centre frequency of an ARFCN four above the ARFCN of the wanted signal. This signal is static, continuous and unmodulated.
c) The second interfering signal is on an ARFCN eight above the ARFCN of the wanted signal. This signal is static, continuous and GMSK modulated by random data (I1).
The amplitude of both the interfering signals is set according to table 14.18-8.
d) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 04.60, 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
e) Once the number of blocks transmitted with the current coding scheme as counted in step d) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.
f) The SS repeats steps d) and e) with the two unwanted signals having frequencies corresponding to ARFCN four and eight below the ARFCN of the wanted signal.

b) The first interfering signal is on a frequency equal to the centre frequency of an ARFCN four above the ARFCN of the wanted signal. This signal is static, continuous and unmodulated.
c) The second interfering signal is on an ARFCN eight above the ARFCN of the wanted signal. This signal is static, continuous and GMSK modulated by random data (I1).

14.18.5.1 Definition
|
Blocking is a measure of the ability of the receiver to receive a modulated wanted input signal in the presence of an unwanted input signal, on frequencies other than those of the spurious responses or the adjacent channels, without exceeding a given degradation. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.

14.18.5.3 Test purpose
|
1. To verify that the in band blocking performance is met without exceeding the total number of allowed in band spurious responses. An allowance is made for the statistical significance of the test.
2. To verify that at selected out of band frequencies, the out of band blocking performance is met without exceeding the total number of allowed out of band spurious responses. An allowance is made for the statistical significance of the test.
NOTE: Not all of the possible out of band frequencies are tested as this results in excessive test time. However, the total number of out of band spurious responses, specified in 3GPP TS 05.05, is allowed to ensure a fair test of the MS.

14.18.5.4 Method of test
|
Initial conditions
A call is set up according to the generic call set up procedure, except the BCCH frequency list shall be empty, on a TCH with an arbitrary ARFCN in the range supported by the MS. The power control level is set to maximum power. The ARFCN of the BCCH shall be the same - or at an offset of +/- 2 channels, than that of the ARFCN for the TCH.
The SS transmits EGPRS RLC data blocks containing random data.
In addition to the wanted Test Signal, the SS transmit a static unmodulated continuous interfering signal (Standard Test Signal I0).
Test procedure
For the ACK/NACK test steps the maximum number of supported time slots shall be used, and for the USF test steps the maximum supported symmetrical UL slot configuration shall be used.
For GMSK Modulation:
a) The SS is set to produce a static GMSK wanted signal and a static interfering signal at the same time. The SS sets the amplitude of the wanted signal to 4 dB above the reference sensitivity level specified in table 14.18-3a for PDTCH channel and in table 14.18-4a for USF channel with correction values as specified in 3GPP TS 05.05 subclause 6.2.
b) The SS transmits packets on PDTCH using MCS-4 coding to MS on all allocated timeslots.
c) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ± 600 kHz are excluded.
NOTE: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
d) The frequencies at which the test is performed (adjusted to an integer multiple of 200 kHz channels most closely approximating the absolute frequency of the calculated blocking signal frequency) are the combined frequencies from i), ii) and iii) which follow:
i) The total frequency range formed by:
GSM 400 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 3,6 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 3,6 MHz).
GSM 700 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 7,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 7,5 MHz).
GSM 850 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 12,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 12,5 MHz).
P-GSM 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 12,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 12,5 MHz).
E-GSM 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 17,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 17,5 MHz).
DCS 1 800: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 37,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 37,5 MHz).
PCS 1 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 30 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 30 MHz).
and
the frequencies +100 MHz and -100 MHz from the edge of the relevant receive band.
Measurements are made at 200 kHz intervals.
ii) The three frequencies IF1, IF1 + 200 kHz, IF1 - 200 kHz.
iii) The frequencies:
mFlo + IF1;
mFlo - IF1;
mFR;
where m is all positive integers greater than or equal to 2 such that either sum lies in the range 100 kHz to 12,75 GHz.
The frequencies in step ii) and iii) lying in the range of frequencies defined by step i) above need not be repeated.
Where:
Flo - local oscillator applied to first receiver mixer
IF1 ... IFn - are the n intermediate frequencies
Flo, IF1, IF2 ... IFn - shall be declared by the manufacturer in the PIXIT statement
3GPP TS 51.010-1 annex 3.
e) The level of the unwanted signal is set according to table 14.18-9.

f) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 04.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
g) Once the number of blocks transmitted with the current coding scheme as counted in step f) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.
If a failure is indicated, it is noted and counted towards the allowed exemption total. In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
h) The SS sets the value of the USF/MCS-1 such as to allocate the uplink to the MS.
i) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.

j) The level of the unwanted signal is set according to table 14.18-9.
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-1 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
For 8-PSK Modulation:
a) The SS is set to produce a static 8-PSK wanted signal and a static interfering signal at the same time. The SS sets the amplitude of the wanted signal to 4 dB above the reference sensitivity level specified in table 14.18-3b for PDTCH channel and in table 14.18-4b for USF channel with correction values as specified in 3GPP TS 05.05 subclause 6.2;

where m is all positive integers greater than or equal to 2 such that either sum lies in the range 100 kHz to 12,75 GHz.
The frequencies in step ii) and iii) lying in the range of frequencies defined by step i) above need not be repeated.
Where:
Flo - local oscillator applied to first receiver mixer

NOTE 4: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.

k) The level of the unwanted signal is set according to table 14.18-9.

14.18.5.5 Test requirements
|
The block error ratio as calculated by the SS for different channels and coding schemes shall not exceed the conformance requirement. Testing the conformance requirement can be done either in the classical way with a fixed minimum number of samples (refer to section 14.18.5.5.2) or using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with performance not on the limit (refer to section 14.18.5.5.1). Both methods are based on a bad DUT factor M = 1.5.
This shall apply under normal test voltage and ambient temperature, and with the interfering signal at any frequency in the range specified.
The following exceptions are allowed:
GSM 400: A maximum of three failures in the band 457,6 MHz to 473,6 MHz for GSM450 and in the band 486,0 MHz to 502,0 MHz for GSM480

A maximum of 24 failures in the combined bands 100 kHz to 727 MHz and 782 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
GSM 810: A maximum of six failures in the frequency band 831 MHz to 886 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).

A maximum of 24 in the combined bands 100 kHz to 1 785 MHz and 1 920 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
PCS 1 900: A maximum of twelve failures in the band 1 910 MHz to 2 010 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 in the combined bands 100 kHz to 1 910 MHz and 2 010 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
If the number of failures does not exceed the maximum allowed figures stated above, the test of 14.18.5.4 is repeated at the frequencies at which the failures occurred. The level of the unwanted signal is set to 70 dBuVemf( ) and the performance requirement is once again that stated above.

14.18.5.5.1 Statistical testing of blocking and spurious response performance with early decision
|
For more information on statistical testing of blocking and spurious response performance, especially the definition of limit lines, refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass ≠ Ffail As the blocking test case comprises of many BLER tests the wrong decision risk for a fail decision of one single error rate test must be smaller than the wrong decision risk for a pass decision to avoid an increased probability of an erroneous fail decision.
Fpass = 0.2%
Ffail = 0.02%
Wrong decision probability D per test step:
Dpass ≠ Dfail
Dpass = 0.008%
Dfail = 0.0008%
Parameters for limit lines:
1. Dpass = 0.008% wrong decision probability per test step for early pass decision.
Dfail = 0.0008% wrong decision probability per test step for early fail decision.
2. M = 1.5 bad DUT factor
3. ne number of (error) events.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
For an early decision a minimum number of measured (error) events are necessary.
For an early pass decision ne ≥ 1
For an early fail decision ne ≥ 8
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The statistical testing of the conformance requirement is done using table 14.18.5-1.

14.18.5.5.2 Fixed testing of blocking and spurious response performance with minimum number of samples
|
The fixed testing of the conformance requirement is done using the minimum number of samples and the limit BLER given in table 14.18‑2.
14.18.5a Blocking and spurious response in EGPRS2A configuration
14.18.5a.1 Definition
Blocking is a measure of the ability of the receiver to receive a modulated wanted input signal in the presence of an unwanted input signal, on frequencies other than those of the spurious responses or the adjacent channels, without exceeding a given degradation. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
14.18.5a.2 Conformance requirement
1. The blocking characteristics of the receiver are specified separately for in-band and out-of-band performance as identified in 3GPP TS 45.005 subclause 5.1.
2. The block error rate (BLER) performance for PDTCH/DAS-5 to 12 shall not exceed 10 % depending on Coding Schemes and for USF/DAS-5 to 12 shall not exceed 1 % when the following signals are simultaneously input to the receiver; 3GPP TS 45.005, subclause 6.2:
- a useful signal at frequency f0, 3 dB above the reference sensitivity level specified in table 14.18.1a-1 for 8-PSK, 16QAM and 32QAM modulation for PDTCH channels; and in tables 14.18.1a-2 for 8-PSK 16QAM and 32QAM modulation for USF channel with correction values as specified in 3GPP TS 45.005 subclause 6.2;
- a continuous, static sine wave unwanted signal at a level as in the table 14.18-9a and 14.18.9b, and at a frequency (f) which is an integer multiple of 200 kHz.
with the following exceptions, called spurious response frequencies:
a) GSM 400: in band, for a maximum of three occurrences. 3GPP TS 45.005, subclause 5.1.
GSM 700, GSM 850 or GSM 900: in band, for a maximum of six occurrences (which if grouped shall not exceed three contiguous occurrences per group). 3GPP TS 45.005, subclause 5.1.
DCS 1 800 and PCS 1 900: in band, for a maximum of twelve occurrences (which if grouped shall not exceed three contiguous occurrences per group). 3GPP TS 45.005, subclause 5.1.
b) out of band, for a maximum of 24 occurrences (which if below f0 and grouped shall not exceed three contiguous occurrences per group). 3GPP TS 45.005, subclause 5.1.
where the above performance shall be met when the continuous sine wave signal (f) is set to a level of 70 dBµV (emf) (i.e. -43 dBm). 3GPP TS 45.005, subclause 5.1.
14.18.5a.3 Test purpose
1. To verify that the in band blocking performance is met without exceeding the total number of allowed in band spurious responses. An allowance is made for the statistical significance of the test.
2. To verify that at selected out of band frequencies, the out of band blocking performance is met without exceeding the total number of allowed out of band spurious responses. An allowance is made for the statistical significance of the test.
NOTE: Not all of the possible out of band frequencies are tested as this results in excessive test time. However, the total number of out of band spurious responses, specified in 3GPP TS 45.005, is allowed to ensure a fair test of the MS.
14.18.5a.4 Method of test
Initial conditions
A call is set up according to the generic call set up procedure, except the BCCH frequency list shall be empty, on a TCH with an arbitrary ARFCN in the range supported by the MS. The power control level is set to maximum power. The ARFCN of the BCCH shall be the same - or at an offset of +/- 2 channels, than that of the ARFCN for the TCH.
The SS transmits EGPRS RLC data blocks containing random data.
In addition to the wanted Test Signal, the SS transmit a static unmodulated continuous interfering signal (Standard Test Signal I0).
Test procedure
For the ACK/NACK test steps the maximum number of supported time slots shall be used, and for the USF test steps the maximum supported symmetrical UL slot configuration shall be used.
For 8-PSK Modulation:
a) The SS is set to produce a static 8-PSK wanted signal and a static interfering signal at the same time. The SS sets the amplitude of the wanted signal to 4 dB above the reference sensitivity level specified in table 14.18.1a-1 for PDTCH channel and in table 14.18.1a-2 for USF channel with correction values as specified in 3GPP TS 45.005 subclause 6.2;
b) The SS transmits packets on PDTCH using DAS-5 coding to MS on all allocated timeslots.
c) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ±600 kHz are excluded.
NOTE 1: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
d) The frequencies at which the test is performed (adjusted to an integer multiple of 200 kHz channels most closely approximating the absolute frequency of the calculated blocking signal frequency) are the combined frequencies from i), ii) and iii) which follow:
i) The total frequency range formed by:
GSM 400 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 3,6 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 3,6 MHz).

and Flo - (IF1 + IF2 + ... + IFn + 7,5 MHz).

and Flo - (IF1 + IF2 + ... + IFn + 37,5 MHz).
PCS 1 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 30 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 30 MHz).
and
the frequencies +100 MHz and -100 MHz from the edge of the relevant receive band.
Measurements are made at 200 kHz intervals.
ii) The three frequencies IF1, IF1 + 200 kHz, IF1 - 200 kHz.
iii) The frequencies:
mFlo + IF1;
mFlo - IF1;
mFR;
where m is all positive integers greater than or equal to 2 such that either sum lies in the range 100 kHz to 12,75 GHz.
The frequencies in step ii) and iii) lying in the range of frequencies defined by step i) above need not be repeated.
Where:
Flo - local oscillator applied to first receiver mixer
IF1 ... IFn - are the n intermediate frequencies
Flo, IF1, IF2 ... IFn - shall be declared by the manufacturer in the PIXIT statement
3GPP TS 51.010-1 annex 3.
e) The level of the unwanted signal is set according to table 14.18-9a and 14.18-9b.
f) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 44.060, 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 2: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
g) Once the number of blocks transmitted with the current coding scheme as counted in step f) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.

j) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ±600 kHz are excluded.
NOTE 3: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
k) The level of the unwanted signal is set according to table 14.18-9a and 14.18-9b.
l) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
m) Once the number of USF/DAS-7 allocating the uplink for the MS as counted in step l) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
For 16QAM Modulation:
a) The SS is set to produce a static 16QAM wanted signal and a static interfering signal at the same time. The SS sets the amplitude of the wanted signal to 4 dB above the reference sensitivity level specified in table 14.18.1a-1 for PDTCH channel and in table 14.18.1a-2 for USF channel with correction values as specified in 3GPP TS 45.005 subclause 6.2;
b) The SS transmits packets on PDTCH using DAS-8 coding to MS on all allocated timeslots.
c) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ±600 kHz are excluded.
NOTE 4: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.

NOTE 5: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
g) Once the number of blocks transmitted with the current coding scheme as counted in step f) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.

k) The level of the unwanted signal is set according to table 14.18-9a and 14.18-9b.
l) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
m) Once the number of USF/DAS-9 allocating the uplink for the MS as counted in step l) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
For 32QAM Modulation:
a) The SS is set to produce a static 32QAM wanted signal and a static interfering signal at the same time. The SS sets the amplitude of the wanted signal to 4 dB above the reference sensitivity level specified in table 14.18.1a-1 for PDTCH channel and in table 14.18.1a-2 for USF channel with correction values as specified in 3GPP TS 45.005 subclause 6.2;
b) The SS transmits packets on PDTCH using DAS-10 coding to MS on all allocated timeslots.
c) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ±600 kHz are excluded.
NOTE 7: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
d) The frequencies at which the test is performed (adjusted to an integer multiple of 200 kHz channels most closely approximating the absolute frequency of the calculated blocking signal frequency) are the combined frequencies from i), ii) and iii) which follow:
i) The total frequency range formed by:
GSM 400 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 3,6 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 3,6 MHz).
GSM 700 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 7,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 7,5 MHz).
GSM 850 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 12,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 12,5 MHz).
P-GSM 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 12,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 12,5 MHz).
E-GSM 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 17,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 17,5 MHz).
DCS 1 800: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 37,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 37,5 MHz).
PCS 1 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 30 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 30 MHz).
and
the frequencies +100 MHz and -100 MHz from the edge of the relevant receive band.
Measurements are made at 200 kHz intervals.
ii) The three frequencies IF1, IF1 + 200 kHz, IF1 - 200 kHz.
iii) The frequencies:
mFlo + IF1;
mFlo - IF1;
mFR;
where m is all positive integers greater than or equal to 2 such that either sum lies in the range 100 kHz to 12,75 GHz.
The frequencies in step ii) and iii) lying in the range of frequencies defined by step i) above need not be repeated.
Where:
Flo - local oscillator applied to first receiver mixer
IF1 ... IFn - are the n intermediate frequencies
Flo, IF1, IF2 ... IFn - shall be declared by the manufacturer in the PIXIT statement
3GPP TS 51.010-1 annex 3.
e) The level of the unwanted signal is set according to table 14.18-9a and 14.18-9b.
f) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 44.060, 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 8: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
g) Once the number of blocks transmitted with the current coding scheme as counted in step f) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
h) The SS sets the value of the USF/DAS-12 such as to allocate the uplink to the MS.
j) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ±600 kHz are excluded.
NOTE 9: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
k) The level of the unwanted signal is set according to table 14.18-9a and 14.18-9b.
l) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
m) Once the number of USF/DAS-12 allocating the uplink for the MS as counted in step l) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
14.18.5a.5 Test requirements
The block error ratio as calculated by the SS for different channels and coding schemes shall not exceed the conformance requirement. Testing the conformance requirement can be done either in the classical way with a fixed minimum number of samples (refer to section 14.18.5a.5.2) or using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with performance not on the limit (refer to section 14.18.5a.5.1). Both methods are based on a bad DUT factor M = 1.5.
This shall apply under normal test voltage and ambient temperature, and with the interfering signal at any frequency in the range specified.
The following exceptions are allowed:
GSM 400: A maximum of three failures in the band 457,6 MHz to 473,6 MHz for GSM450 and in the band 486,0 MHz to 502,0 MHz for GSM480
A maximum of 24 in the combined bands 100 kHz to 457,6 MHz and 473,6 MHz to 12,75 GHz for GSM 450 and in the combined bands 100 kHz to 486,0 MHz and 502,0 MHz to 12,75 GHz for GSM 480 (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
GSM 710: A maximum of six failures in the frequency band 678 MHz to 728 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).

GSM 750: A maximum of six failures in the frequency band 727 MHz to 782 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 failures in the combined bands 100 kHz to 727 MHz and 782 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
GSM 810: A maximum of six failures in the frequency band 831 MHz to 886 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 failures in the combined bands 100 kHz to 831 MHz and 886 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
GSM 850: A maximum of six failures in the frequency band 849 MHz to 914 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 failures in the combined bands 100 kHz to 849 MHz and 914 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
GSM 900: A maximum of six failures in the band 915 MHz to 980 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 in the combined bands 100 kHz to 915 MHz and 980 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
DCS 1 800: A maximum of twelve failures in the band 1 785 MHz to 1 920 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 in the combined bands 100 kHz to 1 785 MHz and 1 920 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
PCS 1 900: A maximum of twelve failures in the band 1 910 MHz to 2 010 MHz (which, if grouped, shall not exceed three 200 kHz channels per group).
A maximum of 24 in the combined bands 100 kHz to 1 910 MHz and 2 010 MHz to 12,75 GHz (which, if below FR and grouped, shall not exceed three 200 kHz channels per group).
If the number of failures does not exceed the maximum allowed figures stated above, the test of 14.18.5a.4 is repeated at the frequencies at which the failures occurred. The level of the unwanted signal is set to 70 dBuVemf( ) and the performance requirement is once again that stated above.
The number of Error Events recorded in this test shall not exceed the test limit error rate values given above, when using either the accelerated BLER method or the maximum number of samples.
No failures are allowed at this lower unwanted signal level.
14.18.5a.5.1 Statistical testing of blocking and spurious response performance with early decision
For more information on statistical testing of blocking and spurious response performance, especially the definition of limit lines, refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass ≠ Ffail As the blocking test case comprises of many BLER tests the wrong decision risk for a fail decision of one single error rate test must be smaller than the wrong decision risk for a pass decision to avoid an increased probability of an erroneous fail decision.
Fpass = 0.2%
Ffail = 0.02%
Wrong decision probability D per test step:
Dpass ≠ Dfail
Dpass = 0.008%
Dfail = 0.0008%
Parameters for limit lines:
1. Dpass = 0.008% wrong decision probability per test step for early pass decision.
Dfail = 0.0008% wrong decision probability per test step for early fail decision.
2. M = 1.5 bad DUT factor
3. ne number of (error) events.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
For an early decision a minimum number of measured (error) events are necessary.
For an early pass decision ne ≥ 1
For an early fail decision ne ≥ 8
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The statistical testing of the conformance requirement is done using table 14.18.5a‑1.

14.18.5a.5.2 Fixed testing of blocking and spurious response performance with minimum number of samples
The fixed testing of the conformance requirement is done using the minimum number of samples and the limit BLER given in table 14.18‑2.
14.18.5b Blocking and spurious response in DLMC configuration
14.18.5b.1 Definition
Blocking is a measure of the ability of the receiver to receive a modulated wanted input signal in the presence of an unwanted input signal, on frequencies other than those of the spurious responses or the adjacent channels, without exceeding a given degradation. "Wanted signal" in this test is the signal generated by the transmitted RLC data blocks.
14.18.5b.2 Conformance requirement
1. The blocking characteristics of the receiver are specified separately for in-band and out-of-band performance as identified in 3GPP TS 45.005 subclause 5.1.
2. In case of DLMC configuration, when MS is configured according to subclause 6.1a. The block error rate (BLER) performance for PDTCH/MCS1 to 4 shall not exceed 10 % and for USF/MCS1 to 4 shall not exceed 1 % when the following signals are simultaneously input to the receiver:- for GSM 850, GSM 900, DCS 1800 and PCS 1900 MS two useful signals, modulated with GMSK at frequencies fo and f1, located at
- the maximum supported DLMC carrier frequency spacing as defined in table 6a-1 when the blocking signal is located in the out-of-band frequency range defined in tables 5.1-1a, 5.1-1c, 5.1-1d and 5.1-1e.
- the maximum supported DLMC carrier frequency spacing and all lower carrier frequency spacings according to table 5.1-1i when the blocking signal is located in the in-band frequency range defined in tables 5.1-1a, 5.1-1c, 5.1-1d and 5.1-1e.
and at a signal level X dB above the input levels in table 1a, adjusted by the correction factors of table 6.2‑4, where X is specified in table 5.1‑5c;
In addition, for an MS indicating support for non-contiguous intra-band reception, and in case of DLMC configuration, the reference performance as specified in table 6.2-5 apply with the two useful signals at frequencies fo and f1 located at a larger frequency spacing than the maximum supported DLMC carrier frequency spacing.
‑ a blocking signal that is either
- a continuous, static sine wave signal at a frequency (f) which is an integer multiple of 200 kHz, when located between the useful signals, or when located in the out-of-band frequency range, and at a signal level as in table 5.1-5c or
- a static signal at a frequency (f) modulated with 5 MHz W-CDMA according to 3GPP TS 25.101 annex C.4, when located outside the useful signals and
- within the in-band frequency region, at an offset between the centre frequency of the blocking signal and the useful signal of 2,7 MHz or more in steps of 5 MHz up to the edges of the in-band frequency band, and
- at a signal level as in table 5.1‑5c.
with the following exceptions, called spurious response frequencies:
a) GSM 900 MS and GSM 850 MS in band, for a maximum of one occurrence;
DCS 1 800 and PCS 1 900 MS in band, for a maximum of two occurrences;
b) out of band, for a maximum of 24 occurrences (which if grouped shall not exceed three contiguous occurrences per group).
where the above performance shall be met when the blocking signal (f) is set to a level of 57+X dBµV (emf) (-56+X dBm) in the inband frequency range and 70 dBµV (emf) (‑43 dBm) in the out-of-band frequency range.
When more than one useful signal frequency is considered, the maximum number of allowed occurrences for the spurious response frequencies applies separately to each useful signal frequency.
In case of DLMC configuration, requirements for inter-band reception are only defined in the out-of-band frequency region for band combinations (GSM 850, PCS1900) and (GSM 900, DCS 1800). In this case, the requirements for each frequency band apply using one useful signal in each band.
An MS indicating support for DLMC shall in addition to DLMC specific performance requirements, comply with the requirements in Table 5.1-2a and Table 5.1-4.
NOTE: For testing effort reasons, in case of DLMC configuration, and a MS indicating support for DLMC inter-band reception, it may be considered sufficient to perform the test in the out-of-band frequency range only for the inter-band reception configuration.

14.18.5b.3 Test purpose
1. To verify that the in-band blocking performance is met without exceeding the total number of allowed in-band spurious responses. An allowance is made for the statistical significance of the test.
2. To verify that at selected out of band frequencies, the out of band blocking performance is met without exceeding the total number of allowed out of band spurious responses. An allowance is made for the statistical significance of the test.
NOTE: Not all of the possible out of band frequencies are tested as this results in excessive test time. However, the total number of out of band spurious responses, specified in 3GPP TS 45.005, is allowed to ensure a fair test of the MS.
14.18.5b.4 Method of test
Initial conditions
A call is set up according to the generic call set up procedure, except the BCCH frequency list shall be empty, on a TCH with an arbitrary ARFCN in the range supported by the MS. The power control level is set to maximum power. The ARFCN of the BCCH shall be the same - or at an offset of +/- 2 channels, than that of the ARFCN for the TCH.
The SS transmits EGPRS RLC data blocks containing random data.
In addition to the wanted Test Signals, the SS transmit a static unmodulated continuous interfering signal (Standard Test Signal I0).Or a static signal modulated with 5 MHz W-CDMA according to 3GPP TS 25.101 annex C.4
Test procedure
For the ACK/NACK test steps the maximum number of supported time slots shall be used, and for the USF test steps the maximum supported symmetrical UL slot configuration shall be used.
For GMSK Modulation:
a) The SS is set to produce 2 static GMSK wanted signals and a static interfering signal at the same time.
The two useful signals, modulated with GMSK at frequencies fo and f1, located at
- the maximum supported DLMC carrier frequency spacing as defined in 3GPP TS 45.005 table 6a-1 when the blocking signal is located in the out-of-band frequency range defined in 3GPP TS 45.005 tables 5.1-1a, 5.1-1c, 5.1-1d and 5.1-1e.
- the maximum supported DLMC carrier frequency spacing and all lower carrier frequency spacings according to3GPP TS 45.005 table 5.1-1i when the blocking signal is located in the in-band frequency range defined in 3GPP TS 45.005 tables 5.1-1a, 5.1-1c, 5.1-1d and 5.1-1e.
and at a signal level X+1 dB above the input levels in table 14.18.3a, where X is specified in 3GPP TS 45.005 table 5.1‑5c for PDTCH channel and signal level X+1 dB above the input levels in table 14.18-4a for USF channel with correction values as specified in 3GPP TS 45.005 subclause 6.2.b) The SS transmits packets on PDTCH using MCS-4 coding to MS on all allocated timeslots.
c) The unwanted signal is of frequency FB. That is either
- a continuous, static sine wave signal at a frequency (f) which is an integer multiple of 200 kHz, when located between the useful signals, or when located in the out-of-band frequency range, and at a signal level as in table 14.18.5b-1, or
- a static signal at a frequency (f) modulated with 5 MHz W-CDMA according to 3GPP TS 25.101 annex C.4, when located outside the useful signals and
- within the in-band frequency region, at an offset between the centre frequency of the blocking signal and the useful signal of 2,7 MHz or more in steps of 5 MHz up to the edges of the in-band frequency band, and at a signal level as in table 14.18.5b-1
It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ± 600 kHz are excluded.
NOTE: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
d) The frequencies at which the test is performed (adjusted to an integer multiple of 200 kHz channels most closely approximating the absolute frequency of the calculated blocking signal frequency) are the combined frequencies from i), ii) and iii) which follow:
i) The total frequency range formed by:
GSM 850 the frequencies between Flo + (IF1 + IF2 + ... + IFn + 12,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 12,5 MHz).
P-GSM 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 12,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 12,5 MHz).
E-GSM 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 17,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 17,5 MHz).
DCS 1 800: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 37,5 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 37,5 MHz).
PCS 1 900: the frequencies between Flo + (IF1 + IF2 + ... + IFn + 30 MHz)
and Flo - (IF1 + IF2 + ... + IFn + 30 MHz).
and
the frequencies +100 MHz and -100 MHz from the edge of the relevant receive band.
Measurements are made at 200 kHz intervals.
ii) The three frequencies IF1, IF1 + 200 kHz, IF1 - 200 kHz.
iii) The frequencies:
mFlo + IF1;
mFlo - IF1;
mFR;
where m is all positive integers greater than or equal to 2 such that either sum lies in the range 100 kHz to 12,75 GHz.
The frequencies in step ii) and iii) lying in the range of frequencies defined by step i) above need not be repeated.
Where:
Flo - local oscillator applied to first receiver mixer
IF1 ... IFn - are the n intermediate frequencies
Flo, IF1, IF2 ... IFn - shall be declared by the manufacturer in the PIXIT statement

NOTE 1: f refers to the interfering blocker signal, and fo and f1 refer to the wanted signals being considered.
NOTE 2: For definition of small MS, see subclause 1.1.
NOTE 3: X is the increase level above input level for reference performance as defined in subclause 5.1.2.
f) The SS counts the number of blocks transmitted with current coding scheme and the number of these blocks not acknowledged based on the content of the Ack/Nack Description information element (see 3GPP TS 44.60, subclause 12.3) in the Packet Downlink Ack/Nack as sent from the MS to the SS on the PACCH.
NOTE 1: Due to the error rates related to the USF, the MS is likely to occasionally miss its USF for transmitting the Packet Downlink Ack/Nack. As this requirement is not verified in this part of the test, the SS then again assigns uplink resources so the MS can send this message.
g) Once the number of blocks transmitted with the current coding scheme as counted in step f) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters.
If a failure is indicated, it is noted and counted towards the allowed exemption total. In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
h) The SS sets the value of the USF/MCS-4 such as to allocate the uplink to the MS.
i) The unwanted signal is of frequency FB. It is applied in turn on the subset of frequencies calculated at step d) in the overall range 100 kHz to 12,75 GHz, where FB is an integer multiple of 200 kHz.
However, frequencies in the range FR ±600 kHz are excluded.
NOTE 2: Allowance must be made for possible spurious signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3, 4, 5, etc.
j) The level and configuration of the unwanted signal is set according to step c).
k) The SS counts the number of times the USF is allocated to the MS, and the number of times the MS does not transmit while being allocated the uplink.
l) Once the number of USF/MCS-4 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14.18-2, the SS calculates the Block error ratio. The SS resets both counters. If a failure is indicated, it is noted and counted towards the allowed exemption total.
In the case of failures discovered at the predicted frequencies at steps d i), ii) or iii) the test is repeated on the adjacent channels ±200 kHz away. If either of these two frequencies fail then the next channel 200 kHz beyond is also be tested. This process is repeated until all channels constituting the group of failures is known.
14.18.5b.5 Test requirements
The block error ratio as calculated by the SS for different channels and coding schemes shall not exceed the conformance requirement. Testing the conformance requirement can be done either in the classical way with a fixed minimum number of samples (refer to section 14.18.5b.5.2) or using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with performance not on the limit (refer to section 14.18.5b.5.1). Both methods are based on a bad DUT factor M = 1.5.
This shall apply under normal test voltage and ambient temperature, and with the interfering signal at any frequency in the range specified.
The following exceptions are allowed:
GSM 900 MS and GSM 850: MS in band, for a maximum of one occurrence;
DCS 1 800 and PCS 1 900: MS in band, for a maximum of two occurrences;
All Bands: out of band, for a maximum of 24 occurrences (which if grouped shall not exceed three contiguous occurrences per group).where the above performance shall be met when the blocking signal (f) is set to a level of 57+X dBµV (emf) (-56+X dBm) in the inband frequency range and 70 dBµV (emf) (‑43 dBm) in the out-of-band frequency range.
When more than one useful signal frequency is considered, the maximum number of allowed occurrences for the spurious response frequencies applies separately to each useful signal frequency. The number of Error Events recorded in this test shall not exceed the test limit error rate values given above, when using either the accelerated BLER method or the maximum number of samples.
No failures are allowed at this lower unwanted signal level.
14.18.5b.5.1 Statistical testing of blocking and spurious response performance with early decision
For more information on statistical testing of blocking and spurious response performance, especially the definition of limit lines refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass ≠ Ffail As the blocking test case comprises of many BLER tests the wrong decision risk for a fail decision of one single error rate test must be smaller than the wrong decision risk for a pass decision to avoid an increased probability of an erroneous fail decision.
Fpass = 0.2%
Ffail = 0.02%
Wrong decision probability D per test step:
Dpass ≠ Dfail
Dpass = 0.008%
Dfail = 0.0008%
Parameters for limit lines:
1. Dpass = 0.008% wrong decision probability per test step for early pass decision.
Dfail = 0.0008% wrong decision probability per test step for early fail decision.
2. M = 1.5 bad DUT factor
3. ne number of (error) events.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
For an early decision a minimum number of measured (error) events is necessary.
For an early pass decision ne ≥ 1
For an early fail decision ne ≥ 8
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The statistical testing of the conformance requirement is done using table 14.18.5b-2.

14.18.6.4 Test Method
|
Initial Conditions
The MS is assumed to be EGPRS attached. The power control parameter ALPHA (α) is set to 0.
The SS establishes a downlink TBF on one timeslot.
The SS commands the MS to request an establishment of the TBF Uplink and to create a channel loop back after demodulation and before decoding. This is achieved by the EGPRS Switched Radio Loopback Mode (3GPP TS 04.14/44.014, subclause 5.5)
Test Procedure
For GMSK Modulation:
a) The SS shall transmit the pseudo-random data using the standard GMSK-modulated test signal in the Mid ARFCN range and the input level at the receiver input shall be 20 dB above the Reference Sensitivity Level.
b) The SS compares the data that it sends to the MS with the data which is looped back from the receiver after demodulation and before decoding.
The SS tests the bit error ratio for the data bits, by examining sequences of at least the minimum number of samples specified in the test requirements. The number of error events is recorded.
c) Step b) is repeated with the input level at the receiver input increased to 73 dBVemf().
d) Step b) is repeated with the input level at the receiver input increased to the following values:
For GSM 400, GSM 700, T-GSM 810, GSM 850 and GSM 900: 98 dBVemf().
For DCS 1 800 and PCS 1 900: 90 dBVemf().
e) The SS fading function is set to EQ.
f) Step b) is repeated with the input level at the receiver input set to 20dB above the reference sensitivity level() and then increased to 73 dBVemf().
g) Steps a) to f) are repeated under extreme test conditions.
For 8PSK Modulation:
a) The SS shall transmit the pseudo-random data using the standard 8PSK-modulated test signal in the Mid ARFCN range and the input level at the receiver input shall be -82 dBm, which level is subject to adjustment according to correction table in subclause 6.2. of 3GPP TS 05.05/45.005. For an EGPRS MS that only supports GMSK modulation in the uplink, a GMSK-modulated signal will be used for UL transmission.
b) The SS compares the data that it sends to the MS with the data which is looped back from the receiver after demodulation and before decoding.
The SS tests the bit error ratio for the data bits, by examining sequences of at least the minimum number of samples specified in the test requirements. The number of error events is recorded.
c) Step b) is repeated with the input level at the receiver input increased to 73 dBVemf().
d) Step b) is repeated with the input level at the receiver input increased to 87 dBVemf().
e) Steps a) to d) are repeated under extreme test conditions.
For 8PSK Modulation with random frequency offset:
a) The SS shall transmit the pseudo-random data using the standard 8PSK-modulated test signal in the Mid ARFCN range and the input level at the receiver input shall be -82 dBm, which level is subject to adjustment according to correction table in subclause 6.2. of 3GPP TS 05.05/45.005. The 8-PSK modulated test signal is randomly offset, on a burst-by-burst basis, by a frequency offset of +/- 0,1ppm. For each burst, the sign of the frequency offset is chosen according to a 511-bit pseudo-random sequence, defined in ITU-T Recommendation O.153. For an EGPRS MS that only supports GMSK modulation in the uplink, a GMSK-modulated signal will be used for UL transmission.
b) The SS compares the data that it sends to the MS with the data which is looped back from the receiver after demodulation and before decoding.
The SS tests the bit error ratio for the data bits, by examining sequences of at least the minimum number of samples specified in the test requirements. The number of error events is recorded.
c) Step b) is repeated with the input level at the receiver input increased to 73 dBµVemf().
d) Step a) to c) are repeated under extreme test conditions.

14.18.7.4 Method of test
|
The SS establishes a downlink TBF in Incremental Redundancy RLC mode, beginning on a Mid ARFCN Range, under the conditions defined in the conformance requirement. The downlink data transfer is preceded with random payload data according to the Incremental Redundancy RLC mode procedures using MCS-9. The throughput between LLC and RLC/MAC layer is determined by the SS on the basis of the amount of successfully delivered LLC data, i.e. the amount of data bits in acknowledged RLC data blocks in the correct order without gaps representing LLC or higher layer data. The long-term throughput is determined until at least 6000 RLC data blocks have been send from RLC/MAC layer to the LLC layer within the MS. The test is repeated in Low and High ARFCN range.
If the END_OF_WINDOW bit in the ack/nack message is not set, the SS shall poll the MS for the next partial bitmap irrespective of the polling period.
If the MS is setting the MS OUT OF MEMORY BIT to 1 in the EGPRS Packet Downlink ACK/NACK message the SS should take care that only NACKED RLC data blocks are retransmitted with MCS 9 and if the MS sets again the MS OUT OF MEMORY BIT to 0 the SS can continue transmitting also new data with MCS 9.
Initial conditions
The SS establishes a downlink EGPRS TBF in Incremental Redundancy RLC mode according to the generic procedures defined in sect. 50, on a Mid ARFCN Range. For the TBF, the SS allocates the maximum number of timeslots according to the multislot capability of the MS under test, applies MCS-9 as the Modulation and Coding Scheme and the maximum RLC downlink window size the number of used time slots allows for the data transfer. The SS commands the MS to use maximum transmit power in the uplink, decreases the transmit power to –96 dBm in the downlink and preserves the fading conditions as static. The power control parameter ALPHA (α) is set to 0.
Procedure
a) Using MSC-9 with Puncturing Scheme 1 (PS1), the SS continues the EGPRS TBF in the downlink by transmitting RLC data blocks with valid Block Sequence Numbers (BSN) within the RLC downlink window of maximum size according to MS's multislot class, and polls the MS for acknowledgements after every polling period of 32 RLC data blocks.
b) The SS updates it's associated acknowledge state array V(B) according to the ack/nack bitmap in the EGPRS Downlink Ack/Nack message transmitted by the MS as a response to polling and shifts the RLC downlink window accordingly.
c) While continuing the transmission of further RLC data blocks with PS1, the SS retransmits, after a delay that corresponds to a round trip time of 120ms, all unacknowledged RLC data blocks with PS2 starting from the oldest unacknowledged RLC blocks.
d) The SS repeats the steps a) to c). For retransmissions of RLC data blocks that have already been retransmitted with PS2, the SS applies PS3 for such blocks and further again PS1 and PS2 in cyclic manner if necessary.
e) Steps a) to d) are repeated until at least 6000 RLC data blocks are transmitted from RLC to LLC layer within the MS, but never more then 18000 RLC data blocks from SS to MS.
NOTE: If the MS needs more than 18000 RLC data blocks received to send 6000 RLC blocks up to the LLC layer it will never fulfil the conformance requirements.
f) The SS calculates the data throughput per time slot between RLC/MAC and LLC layers on the basis of successfully transmitted LLC-data during steps a) to e). For this the lower end of the RLC downlink window can be used to measure the progress of the transmission in terms of amount of data passed on to the LLC.
If n is the number of timeslots, x the position of the lower end of the RLC downlink window, and t is the duration from the beginning of the transmission of RLC data blocks to reaching the stop condition, then the average throughput per timeslot is (x · 592 bit)/(n·t).
g) Steps a) to f) are repeated at Low and High ARFCN ranges.
Test requirements
The long-term throughput per time slot as a result of step f) of the test procedure shall equal or exceed 20kbps on low, mid and high ARFCN range.

Initial conditions
The SS establishes a downlink TBF in Incremental Redundancy RLC mode according to the generic procedures defined in sect. 50, on a Mid ARFCN Range. For the TBF, the SS allocates the maximum number of timeslots according to the multislot capability of the MS under test, applies the applicable Modulation and Coding Scheme according to MS capability, see table 14.18-1. The SS commands the MS to use maximum transmit power in the uplink, decreases the transmit power to tbd dBm in the downlink and preserves the fading conditions as static. The power control parameter ALPHA (α) is set to 0.
Specific PICS statements:
Procedure
a) Using the applicable MCS according to MS capability, see table 14.18-1, with Puncturing Scheme 1 (PS1), the SS continues the TBF in the downlink by transmitting RLC data blocks with valid Block Sequence Numbers (BSN) within the RLC downlink window, and polls the MS for acknowledgements after every polling period of 8 RLC data blocks.
b) The SS updates its associated acknowledge state array V(B) according to the ack/nack bitmap in the EC Downlink Ack/Nack message transmitted by the MS as a response to polling and shifts the RLC downlink window accordingly.
c) While continuing the transmission of further RLC data blocks with PS1, the SS retransmits, after a delay that corresponds to a round trip time of 120ms, all unacknowledged RLC data blocks with PS2 starting from the oldest unacknowledged RLC blocks.
d) The SS repeats the steps a) to c). For retransmissions of RLC data blocks using MCS-9 that have already been retransmitted with PS2, the SS applies PS3 for such blocks and further again PS1 and PS2 in cyclic manner if necessary. For retransmissions of RLC data blocks using MCS-4 that have already been retransmitted with PS2 the SS applies PS1, and then PS2 in a cyclic manner if necessary.
e) Steps a) to d) are repeated until at least 6000 RLC data blocks are transmitted from RLC to LLC layer within the MS, but never more then 18000 RLC data blocks from SS to MS.
NOTE: If the MS needs more than 18000 RLC data blocks received to send 6000 RLC blocks up to the LLC layer it will never fulfil the conformance requirements.
f) The SS calculates the data throughput per time slot between RLC/MAC and LLC layers on the basis of successfully transmitted LLC-data during steps a) to e). For this the lower end of the RLC downlink window can be used to measure the progress of the transmission in terms of amount of data passed on to the LLC.
If n is the number of timeslots, x the position of the lower end of the RLC downlink window, and t is the active time duration of allocated radio blocks carrying RLC data blocks before reaching the stop condition, then the average throughput per timeslot is:
- For MCS-4: (x · 352 bit)/(n·t).
g) Steps a) to f) are repeated at Low and High ARFCN ranges.
Test requirements
The long-term throughput per time slot as a result of step f) of the test procedure shall equal or exceed 6 kbps on low, mid and high ARFCN range.
