14.10.8.1 Definition
|
When a traffic channel supporting a WB-AMR speech codec is activated, the Codec Mode Request is sent by MS in band every other speech frame to indicate to the Network the recommended codec mode of the ACS to use on the downlink.

14.10.8.2 Conformance Requirement
|
For TU3 channel conditions with ideal frequency hopping without DTX activated in GSM900 and GSM850, the MS shall produce Codec Mode Requests with the following accuracy:
- When a carrier to interferer ratio 4 dB higher than a defined upper threshold is applied to the antenna connector, the MS shall request a higher mode with a probability exceeding 90%. This shall be measured immediately after a settling-time of 200 ms.
- When a carrier to interferer ratio 4 dB lower than a defined lower threshold is applied to the antenna connector, the MS shall request a lower mode with a probability exceeding 90%. This shall be measured immediately after a settling-time of 200 ms.
If required, the above test levels shall be reduced by the normalization factor defined in sub-clause 3.3.1 to account for potential improved receiver performances.
For other frequency bands, the propagation profile should be adjusted to: TU1.5 for DCS1800 and PCS1900, TU6 for GSM400 and TU3.6 for GSM700.
NOTE 1: Ideal frequency hopping assumes perfect decorrelation between bursts. For the propagation profile TU3, this is not easily achievable due to the high number of hopping frequencies required. Therefore, performance tests should be performed under ideal frequency hopping conditions for the following propagation profiles: TU50 for GSM900 and GSM850, TU25 for DCS1800 and PCS1900, TU100 for GSM400, and TU60 for GSM700.
3GPP TS 45.009 subclause 3.3.3.3
For T-GSM 810 the requirements for GSM 900 shall apply, apart for those parameters for which a separate requirement exists.

14.10.8.3 Test Purpose
|
1. To verify that the MS does not exceed conformance requirement (for producing codec request) under TUHigh and frequency hopping propagation conditions without DTX with an allowance for the statistical significance of the test.
2. To implicitly verify the correct implementation of the WB-AMR Thresholds and Hysteresis parameters received in either an ASSIGNMENT COMMAND or MODE MODIFY procedure, or through an AMR_CONFIG_REQ or THRESH_REQ message carried in a RATSCCH.
NOTE: This would normally be performed as a signalling test, however due to the complex layer 1 requirements it is verified here. Any future modification or Change Request on this section should take into account this additional test objective.

14.10.8.4.1 Initial conditions
|
A call is set up according to the generic call set up procedure on a TCH/WFS with a hopping pattern in the Mid ARFCN range and covering at least 10 frequencies not exceeding 5 MHz. DTX shall not be activated. Power control level shall be set to maximum power.
The initial configuration indicates the use of the 12.65 mode of AMR only.
The SS transmits Standard Test Signal C1 on the traffic channel.
In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).
- The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. Initially, the unwanted signal is switched off.
- The fading characteristic of the wanted and the interfering signal is TUHigh.
NOTE 1: The fading characteristics shall be TU50 for GSM900, T-GSM 810 and GSM850, TU25 for DCS1800 and PCS1900, TU100 for GSM400, and TU60 for GSM700.

14.10.8.4.2 Procedure
|
STEP 1
1a) The SS uses a Channel Mode Modify procedure to change the active codec set to the following set:
Codec Mode
TCH/WFS in kbit/s
CODEC_MODE_3
12,65
CODEC_MODE_2
8,85
CODEC_MODE_1
6,6
With Initial Codec Mode unspecified, thus the default ICM rule being used and the following decision thresholds and hysteresis values:
MC'/MR'
THR_MC_Dn(MC)/
THR_MR_Dn(MR)
THR_MC_Up(MC)/
THR_MR_Up(MR)
CODEC_MODE_3
18.5 dB
+
CODEC_MODE_2
12.5 dB
20.5 dB
CODEC_MODE_1
14.5 dB
The SS uses the expected Initial Codec Mode (default rule) after sending the mode modify message and commands the MS through the CMC field to use the Initial Codec Mode as well. The SS waits for the MS to change the uplink codec to the expected Initial Codec Mode (default rule).
1b) The SS then sends an AMR_CONF_REQ through a RATSCCH message commanding the MS to use the following ACS:
Codec Mode
TCH/WFS in kbit/s
CODEC_MODE_3
12,65
CODEC_MODE_2
8,85
CODEC_MODE_1
6,6
With the Initial Codec Mode set to the 12.65 kbit/s mode and the following decision thresholds and hysteresis values:
MC'/MR'
THR_MC_Dn(MC)/
THR_MR_Dn(MR)

Thr3d = 12.5 dB
+
CODEC_MODE_2
Thr2d = 6.5 dB
Thr2u = 14.5 dB
CODEC_MODE_1
Thr1u = 8.5 dB
The SS switches the downlink codec to the Initial Codec Mode 12 frames after sending the AMR_CONF_REQ message and commands the MS through the CMC field to use the requested Initial Codec Mode. The SS waits for the MS to change the uplink codec to the expected Initial Codec Mode, 12 frames after receiving the ACK_OK message.
The SS waits until the MS indicates in the CMR that the 12.65 kbit/s is the recommended downlink codec mode.
If the MS never reaches that point then the test is failed.
The downlink radio environment is altered so that the carrier to interference ratio is set to 4 dB above the highest of the upwards thresholds Thr2u. The SS waits 500ms.
1c) The downlink radio environment is altered so that the carrier to interference ratio is reduced to 4 dB below the highest of the downwards thresholds Thr1d. The SS increments the counter for ‘C/I decreases below thresholds’.
1d) The SS checks the CMR received from the MS 200ms after the carrier to interference has been altered. If the CMR indicates that the MS recommends to use the 8.85 kbit/s or a lower codec mode in the downlink, then the SS should increment the successful C/I decrease event counter. Otherwise, the SS should increment the unsuccessful C/I decrease event counter.
1e) The SS switches the downlink codec mode to 8.85 kbit/s and waits for 0.5s.
1f) The downlink radio environment is altered so that the carrier to interference ratio is reduced to 4 dB below the lowest of the downwards thresholds Thr2d. The SS increments the counter for ‘C/I decreases below thresholds’.
1g) The SS checks the CMR received from the MS 200ms after the carrier to interference has been altered. If the CMR indicates that the MS recommends to use the 6.6 kbits/s codec mode in the downlink, then the SS should increment the successful C/I decrease event counter. Otherwise, the SS should increment the unsuccessful C/I decrease event counter.
1h) The SS switches the downlink codec mode to 6.6 kbit/s and waits for 0.5s.
1i) The downlink radio environment is altered so that the carrier to interference ratio is increased to 4dB above the lowest of the upwards thresholds Thr1u. The SS increments the counter for ‘C/I increases above thresholds’.
1j) The SS checks the CMR received from the MS 200ms after the carrier to interference has been altered. If the CMR indicates that the MS recommends to use the 8.85 kbit/s or a higher codec mode in the downlink, then the SS should increment the successful C/I increase event counter. Otherwise, the SS should increment the unsuccessful C/I increase event counter.
1k) The SS switches the downlink codec mode to 8.85 kbit/s and waits for 0.5s.
1l) The downlink radio environment is altered so that the carrier to interference ratio is increased to 4 dB above the highest of the upwards thresholds Thr2u. The SS increments the counter for ‘C/I increases above thresholds’.
1m) The SS checks the CMR received by the MS 200ms after the carrier to interference has been altered. If the CMR indicates that the MS recommends to use 12.65 kbit/s in the downlink, then the SS should increment the successful C/I increase event counter. Otherwise, the SS should increment the unsuccessful C/I increase event counter.
1n) The SS switches the downlink codec mode to 12.65 kbit/s and waits for 0.5s.

14.10.9.2 Conformance Requirement
|
3GPP TS 45.009 subclause 3.3.3.3:
For TU3 channel conditions with ideal frequency hopping without DTX activated in GSM900 and GSM850, the MS shall produce Codec Mode Requests with the following accuracy:
- When a carrier to interferer ratio 4 dB higher than a defined upper threshold is applied to the antenna connector, the MS shall request a higher mode with a probability exceeding 90%. This shall be measured immediately after a settling-time of 200 ms.
- When a carrier to interferer ratio 4 dB lower than a defined lower threshold is applied to the antenna connector, the MS shall request a lower mode with a probability exceeding 90%. This shall be measured immediately after a settling-time of 200 ms.
If required, the above test levels shall be reduced by the normalization factor defined in sub-clause 3.3.1 to account for potential improved receiver performances.
For other frequency bands, the propagation profile should be adjusted to: TU1.5 for DCS1800 and PCS1900, TU6 for GSM400 and TU3.6 for GSM700.
NOTE 1: Ideal frequency hopping assumes perfect decorrelation between bursts. For the propagation profile TU3, this is not easily achievable due to the high number of hopping frequencies required. Therefore, performance tests should be performed under ideal frequency hopping conditions for the following propagation profiles: TU50 for GSM900 and GSM850, TU25 for DCS1800 and PCS1900, TU100 for GSM400, and TU60 for GSM700.
NOTE 2: Receivers with improved performance may exceed the minimum requirements reflected by the normalisation factor defined in sub-clause 3.3.1. The normalisation factor, reflecting the improved performance, may depend on the carrier to interference ratio (C/I). Therefore, the conformance test of these receivers may require normalisation factors to be provided for each nominal C/I of the test.
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.

NOTE: The C/I values used throughout this test have been carefully selected to ensure no values above 16dB are signalled, low C/I values will not conflict with the synchronisation requirements in TS 45.010, and also to ensure the C/I values are shared between upward and downward applications. Any future modification or Change Request on this section should take into account these aspects.

1m) The SS checks the CMR received by the MS 200ms after the carrier to interference has been altered.

|
14.11.1.1.4.2 Procedure
|
a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).
The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.
The fading characteristic of the wanted and the interfering signal is TUHigh.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.1-2 or 14.11.1-3.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the number of residual bit error events for the bits of the class II, by examining at least the minimum number of samples of consecutive bits of class II. Bits are only taken from those frames not signalled as erased.
f) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.
Maximum/Minimum Duration of Test
Maximum: 10 minutes (GSM850), 10 minutes (GSM900), 10 minutes (DCS1800), 10 minutes (PCS1900).
Minimum: 4 minutes (GSM850), 4 minutes (GSM900), 2 minutes (DCS1800), 2 minutes (PCS1900).

14.11.1.1.5 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7 (A7.1.3.2)
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure Annex 7 figure A7.1.3.1.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error)
For an early fail decision ne ≥ 7
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in tables 14.11.1-2 or 14.11.1-3.

A call is set up according to the generic call set up procedure on a TCH/FS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal).
The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).
14.11.1.1a.4.2 Procedure
a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).
The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.
The fading characteristic of the wanted and the interfering signal is TUHigh.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.1.1a-2 or 14.11.1.1a-3.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the number of residual bit error events for the bits of the class II, by examining at least the minimum number of samples of consecutive bits of class II. Bits are only taken from those frames not signalled as erased.
f) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.
Maximum/Minimum Duration of Test
Maximum: 10 minutes (GSM850), 10 minutes (GSM900), 10 minutes (DCS1800), 10 minutes (PCS1900).
Minimum: 4 minutes (GSM850), 4 minutes (GSM900), 2 minutes (DCS1800), 2 minutes (PCS1900)
14.11.1.1a.5 Test requirement
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7 (A7.1.3.2)
Before limit checking is valid the minimum test time due to fading needs to be considered:

a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).
The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.
The fading characteristic of the wanted and the interfering signal is TUHigh.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14-63 or 14-64.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 10,2 kbit/s and steps b) to e) are repeated.
g) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,95 kbit/s and steps b) to e) are repeated.
h) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.
i) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.
j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.
k) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.
l) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.

14.11.2.1.5 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.2.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error)
For an early fail decision ne ≥ 7
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in tables 14-63 or 14-64.

14.11.2.1a DARP Phase 1 Speech bearer test TCH/AFS DTS-1 in TIGHTER configuration
14.11.2.1a.1 Definition
The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver with additional TIGHTER requirements to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.
14.11.2.1a.2 Conformance requirement
1. A MS indicating support for TIGHTER capability (see 3GPP TS 24.008) shall fulfil the additional requirements in table 2ad for co channel interference (C/Ic), table 2af for adjacent channel (200 kHz) interference (C/Ia1), and the additional requirements in table 2ae for wanted signals on GMSK modulated channels for the test scenarios defined in annex L. The reference performance shall be:
- For speech channels (TCH/FS, TCH/HS, TCH/EFS, TCH/AFSx, TCH/AHSx, TCH/WFSx ) FER: £ 1 %
2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition to table 6.3-6, for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ad, 2ae, and 2af at the corresponding interference ratio C/Ic, C/I1, and C/Ia1, respectively.
3GPP TS 45.005, subclause 6.3
14.11.2.1a.3 Test purpose
To verify that the MS does not exceed the first conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.
To verify that the MS does not exceed the second conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.
14.11.2.1a.4 Method of test
14.11.2.1a.4.1 Initial conditions
A call is set up according to the generic call set up procedure on a TCH/AFS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The multirate configuration indicates the use of a codec set limited to 12,2 kbit/s.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.
The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).
14.11.2.1a.4.2 Procedure
a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).
The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.
The fading characteristic of the wanted and the interfering signal is TUHigh.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.2.1a-2 or 14.11.2.1a-3.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 10,2 kbit/s and steps b) to e) are repeated.
g) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,95 kbit/s and steps b) to e) are repeated.
h) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.
i) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.
j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.
k) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.
l) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated
Maximum/Minimum Duration of Test
Maximum: 75 minutes (GSM850), 75 minutes (GSM900), 75 minutes (DCS1800), 75 minutes (PCS1900).
Minimum: 27 minutes (GSM850), 26 minutes (GSM900), 13 minutes (DCS1800), 12 minutes (PCS1900).
14.11.2.1a.5 Test requirement
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Before limit checking is valid the minimum test time due to fading needs to be considered:

14.11.2.2.4.1 Initial conditions
|
A call is set up according to the generic call set up procedure on a TCH/AFS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The multirate configuration indicates the use of a codec set limited to 12,2 kbit/s.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.
The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.2.2.4.2 Procedure
|
a) In addition to the wanted signal, the SS produces one further interfering signal to produce scenario DTS-4.
A signal of type I5 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.2.2-2 or 14-11.2.2-3.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.
Maximum/Minimum Duration of Test
Maximum: 19 minutes (GSM850), 19 minutes (GSM900), 19 minutes (DCS1800), 19 minutes (PCS1900).
Minimum: 7 minutes (GSM850), 6 minutes (GSM900), 3 minutes (DCS1800), 3 minutes (PCS1900).

14.11.2.2.5 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error)
For an early fail decision ne ≥ 7
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in tables 14.11.2.2-2 or 14.11.2.2-3.

14.11.2.3.4.2 Procedure
|
a) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-2.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.2.3-2 or 14.11.2.3-3, and sets the fading characteristic of the signal to TUHigh..
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.
g) The SS discontinues all interfering signals.
h) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-3.
A signal of type I4 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one lower than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.
i) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,95 kbit/s and steps b) to e) are repeated.
j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.
k) The SS discontinues all interfering signals.
l) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-5.
A signal of type I5 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

14.11.2.3.5 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error)
For an early fail decision ne ≥ 7
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in tables 14.11.2.3-2 or 14.11.2.3-3.

14.11.2.3a DARP Phase 1 Speech bearer test TCH/AFS DTS-2/3/5 in TIGHTER configuration
14.11.2.3a.1 Definition
The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver with additional TIGHTER requirements to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.
14.11.2.3a.2 Conformance requirement
1. A MS indicating support for TIGHTER capability (see 3GPP TS 24.008) shall fulfil the additional requirements in table 2ad for co channel interference (C/Ic), table 2af for adjacent channel (200 kHz) interference (C/Ia1), and the additional requirements in table 2ae for wanted signals on GMSK modulated channels for the test scenarios defined in annex L. The reference performance shall be:
- For speech channels (TCH/FS, TCH/HS, TCH/EFS, TCH/AFSx, TCH/AHSx, TCH/WFSx ) FER: £ 1 %
2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition to table 6.3-6, for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ad, 2ae, and 2af at the corresponding interference ratio C/Ic, C/I1, and C/Ia1, respectively.
3GPP TS 45.005, subclause 6.3
14.11.2.3a.3 Test purpose
To verify that the MS does not exceed the first conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.
To verify that the MS does not exceed the second conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L. The reference performance shall be:
- For speech channels (TCH/FS, TCH/AFSx, TCH/AHSx) FER: 1 %
2. The values in table 2o are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2o at the corresponding C/I1.

14.11.3.1.4.1 Initial conditions
|
A call is set up according to the generic call set up procedure on a TCH/AHS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The multirate configuration indicates the use of a codec set limited to 7,95 kbit/s.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.
The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.3.1.4.2 Procedure
|
a) In addition to the wanted signal, the SS produces one further interfering signal to produce scenario DTS-1.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.3.1-2 or 14.11.3.1-3.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib and II, by examining at least the minimum number of samples of consecutive bits of class Ib and II. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully if it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.
g) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.
h) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.
i) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.
m) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.
Maximum/Minimum Duration of Test
Maximum: 56 minutes (GSM850), 56 minutes (GSM900), 56 minutes (DCS1800), 56 minutes (PCS1900).
Minimum: 41 minutes (GSM850), 38 minutes (GSM900), 19 minutes (DCS1800), 18 minutes (PCS1900).

14.11.3.1.5 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.2.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error)
For an early fail decision ne ≥ 7
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in tables 14.11.3.1-2 or 14.11.3.1-3.

14.11.3.1a DARP Phase 1 Speech bearer test TCH/AHS DTS-1 in TIGHTER configuration
14.11.3.1a.1 Definition
The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver with additional TIGHTER requirements to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.
14.11.3.1a.2 Conformance requirement
1. A MS indicating support for TIGHTER capability (see 3GPP TS 24.008) shall fulfil the additional requirements in table 2ad for co channel interference (C/Ic), table 2af for adjacent channel (200 kHz) interference (C/Ia1), and the additional requirements in table 2ae for wanted signals on GMSK modulated channels for the test scenarios defined in annex L. The reference performance shall be:
- For speech channels (TCH/FS, TCH/HS, TCH/EFS, TCH/AFSx, TCH/AHSx, TCH/WFSx ) FER: £ 1 %
2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition to table 6.3-6, for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ad, 2ae, and 2af at the corresponding interference ratio C/Ic, C/I1, and C/Ia1, respectively.
3GPP TS 45.005, subclause 6.3
14.11.3.1a.3 Test purpose
To verify that the MS does not exceed the first conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.
To verify that the MS does not exceed the second conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.
14.11.3.1a.4 Method of test
14.11.3.1a.4.1 Initial conditions
A call is set up according to the generic call set up procedure on a TCH/AHS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The multirate configuration indicates the use of a codec set limited to 7,95 kbit/s.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.
The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).
14.11.3.1a.4.2 Procedure
a) In addition to the wanted signal, the SS produces one further interfering signal to produce scenario DTS-1.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.3.1a-2 or 14.11.3.1a-3.
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib and II, by examining at least the minimum number of samples of consecutive bits of class Ib and II. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully if it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.
g) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.
h) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.
i) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.
j) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.
Maximum/Minimum Duration of Test
Maximum: 56 minutes (GSM850), 56 minutes (GSM900), 56 minutes (DCS1800), 56 minutes (PCS1900).
Minimum: 41 minutes (GSM850), 38 minutes (GSM900), 19 minutes (DCS1800), 18 minutes (PCS1900).
14.11.3.1a.5 Test requirement
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Before limit checking is valid the minimum test time due to fading needs to be considered:

14.11.3.3.4.1 Initial conditions
|
A call is set up according to the generic call set up procedure on a TCH/AHS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The multirate configuration indicates the use of a codec set limited to 7,4 kbit/s.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.
The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.3.3.4.2 Procedure
|
a) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-2.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.3.3-2 or 14.11.3.3-3, and sets the fading characteristic of the signal to TUHigh..
c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.
d) The SS determines the number of residual bit error events for the bits of the class Ib and II, by examining at least the minimum number of samples of consecutive bits of class Ib and II. Bits are only taken from those frames not signalled as erased.
e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully if it is not signalled as erased.
f) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.
g) The SS discontinues all interfering signals.
h) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-3.
A signal of type I4 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one lower than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.
i) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.
j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.
Maximum/Minimum Duration of Test
Maximum: 38 minutes (GSM850), 38 minutes (GSM900), 38 minutes (DCS1800), 38 minutes (PCS1900).
Minimum: 27 minutes (GSM850), 26 minutes (GSM900), 13 minutes (DCS1800), 12 minutes (PCS1900).

14.11.3.3.5 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error)
For an early fail decision ne ≥ 7
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in tables 14.11.3.3-2 or 14.11.3.3-3.

14.12.1.1.4.2 Procedure
|
a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).
The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.
The fading characteristic of the wanted and the interfering signal is TUHigh.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14-12.1.1.4.2 (GSM 900 / 850) and table 14-12.1.1.4.3 (DCS 1800 / 1900).
c) The SS sends a Layer 3 message which does not require a Layer 3 response from the MS. Each repeated L2 frame indicates a frame erasure event.
d) The SS determines the number of frame erasure events during at least the minimum number of samples of FACCH/F frames.
NOTE: These frames will not be consecutive but it is expected that the statistical significance of the tests will not be unduly degraded.

14.12.1.1.4.3 Test requirements
|
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7 (A7.1.3.2)
Wrong decision risk F for one single error rate test:
Fpass = Ffail = F and F = 0.2%
Wrong decision probability D per test step:
Dpass = Dfail = D and D = 0.0085%
Parameters for limit lines:
1. D = 0.000085 wrong decision probability per test step.
2. M = 1.5 bad DUT factor
3. ne number of (error) events. This parameter is the x‑ordinate in figure 14‑1.
4. ns number of samples. The error rate is calculated from ne and ns.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:
Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.
If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.
For an early decision a minimum number of (error) events is necessary.
For an early pass decision ne ≥ 1 (inclusive artificial error).
For an early fail decision ne ≥ 7.
When the target test time has been reached the test is finished and a pass/fail decision can be made.
The error rate measured in this test shall be tested according to the values given in table 14-12.1.1.4.2

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.
14.12.1.2a.2 Conformance requirement

- For signalling channels (FACCH/F, FACCH/H, SDCCH) FER: 5 %
2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ae corresponding interference ratio C/I1.
14.12.1.2a.3 Test purpose
To verify that the MS does not exceed the first conformance requirement for FACCH/F under propagation condition TUhigh with an allowance for the statistical significance of the test.
To verify that the MS does not exceed the second conformance requirement for FACCH/F under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.12.1.2a.4.1 Initial conditions
A call is set up according to the generic call set up procedure on a TCH/F with an ARFCN in the mid ARFCN range. The power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.
The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal).
14.12.1.2a.4.2 Procedure
a) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-2.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.
b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.12.1.2a.4.3-2 (GSM 900 / 850) and table 14.12.1.2a.4.3-4 (DCS 1800 / 1900).
c) The SS sends a Layer 3 message which does not require a Layer 3 response from the MS. Each repeated L2 frame indicates a frame erasure event.

NOTE: These frames will not be consecutive but it is expected that the statistical significance of the tests will not be unduly degraded.
e) The SS discontinues all interfering signals.
f) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-3.
A signal of type I4 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.
A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.
A signal of type I1 using an ARFCN one lower than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.
A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.
g) The SS sets the level of the wanted signal to that indicated by Clev in table 14.12.1.2a.4.3-3 (GSM 900 / 850) and table 14.12.1.2a.4.3-5 (DCS 1800 / 1900).
h) The SS sends a Layer 3 message which does not require a Layer 3 response from the MS. Each repeated L2 frame indicates a frame erasure event.
i) The SS determines the number of frame erasure events during at least the minimum number of samples of FACCH/F frames.
NOTE: These frames will not be consecutive but it is expected that the statistical significance of the tests will not be unduly degraded.
14.12.1.2a.4.3 Test requirements
Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.
For more information on statistical testing of BER/BLER performance, especially the definitions of limit lines refer to Annex 6.2.
Limit checking
Before limit checking is valid the minimum test time due to fading needs to be considered:

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 a 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 GPRS 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 14.16-1.

14.16.1.3 Test purpose
|
NOTE: This test is performed under STATIC propagation conditions to allow implicit testing of the ability of the MS to hop over the full band. The tests under dynamic propagation conditions are better suited to test the minimum input level for reference BLER performance conformance but cannot test hopping over the full band due to limited bandwidth of available fading simulators.
1. To verify that that the MS sends a Packet Not Acknowledge in the Packet Downlink Ack/Nack in case of a the Block Check Sequence indicating a Block Error.
2. To verify that the MS does not exceed conformance requirement 1 for CS-3 and CS-4 under STATIC, TUhigh, HT and RA 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 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.

14.16.1.4.1 Initial conditions
|
NOTE 1: The BA list sent on the BCCH and SACCH 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, the traffic channel may fall on any of the ARFCNs defined in clause 6.
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.
A call is set up according to the generic call set up procedure for packet switched on an ARFCN in the Mid range, on the maximum number of receive timeslots, with the MS transmitting at maximum power. The power control parameter ALPHA (α) is set to 0.
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 3GPP TS 04.14 (subclause 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.

14.16.1.4.2 Procedure
|
a) The SS transmits packets under Static propagation conditions, using CS-3 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 CS-3 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 CS-3 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.
d) Once the number of blocks transmitted with CS-3 as counted in step c) 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.
e) The SS repeats step b) to d) with the following four fading conditions and hopping modes: TUhigh/noFH, TUhigh/FH, HT/noFH and RA/noFH. 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 CS-4 coding with the following three fading conditions: Static/FH, TUhigh/noFH and TUhigh/FH. For these tests with fading channels , the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to f) under extreme test conditions.
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 dBm;
• 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.
j) The SS sets the value of the USF/CS-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/CS-1 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14.16-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) using USF/CS2 coding.
NOTE: Since coding for USF-bits is identical for CS2, CS3, and CS4, it’s not required to perform the step for CS3 or CS4.
n) The SS repeats steps i) to m) under extreme test conditions.
o) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/CS-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.

14.16.1.5 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 o) 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).
NOTE: This is stated in the Rel 99 version of 3GPP TS 05.08.

The minimum input level is the signal level at the MS receiver input at which a certain BLER is met.
14.16.1a.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 input levels according to the table below.

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 05.05, 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. This requirement shall be met for all input levels up to -40 dBm.
3GPP TS 05.05, subclause 6.4
3GPP TS 45.05 subclause 2:
For T-GSM 810 the requirements for GSM 900 shall apply, apart for those parameters for which a separate requirement exists.
14.16.1a.3 Test purpose
NOTE: This test is performed under STATIC propagation conditions to allow implicit testing of the ability of the MS to hop over the full band. The tests under dynamic propagation conditions are better suited to test the minimum input level for reference BLER performance conformance but cannot test hopping over the full band due to limited bandwidth of available fading simulators.
1. To verify that that the MS sends a Packet Not Acknowledge in the Packet Downlink Ack/Nack in case of a the Block Check Sequence indicating a Block Error.
2. To verify that the MS does not exceed conformance requirement 1 for CS-3 and CS-4 under STATIC, TUhigh, HT and RA 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 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.
14.16.1a.4 Method of test
14.16.1a.4.1 Initial conditions
NOTE 1: The BA list sent on the BCCH and SACCH 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, the traffic channel may fall on any of the ARFCNs defined in clause 6.
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.
A call is set up according to the generic call set up procedure for packet switched on an ARFCN in the Mid range, on the maximum number of receive timeslots, with the MS transmitting at maximum power. The power control parameter ALPHA (α) is set to 0.
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 3GPP TS 04.14 (subclause 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.
14.16.1a.4.2 Procedure
a) The SS transmits packets under Static propagation conditions, using CS-3 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 CS-3 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 CS-3 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.
d) Once the number of blocks transmitted with CS-3 as counted in step c) 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.
e) The SS repeats step b) to d) with the following four fading conditions and hopping modes: TUhigh/noFH, TUhigh/FH, HT/noFH and RA/noFH. 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 CS-4 coding with the following three fading conditions: Static/FH, TUhigh/noFH and TUhigh/FH. For these tests with fading channels , the SS does not transmit on the timeslots not allocated to the MS.
g) The SS repeats steps b) to f) under extreme test conditions.
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 dBm;
• 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.
j) The SS sets the value of the USF/CS-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/CS-1 allocating the uplink for the MS as counted in step k) reaches or exceeds the minimum number of blocks as given in table 14.16-2, the SS calculates the Block error ratio. The SS resets both counters.
m) The SS repeats steps j) to l) using USF/CS2 coding.
NOTE: Since coding for USF-bits is identical for CS2, CS3, and CS4, it’s not required to perform the step for CS3 or CS4.
n) The SS repeats steps i) to m) under extreme test conditions.
o) The SS establishes normal test condition and a static channel. The SS sets the value of the USF/CS-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.
14.16.1a.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 o) 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).
NOTE: This is stated in the Rel 99 version of 3GPP TS 05.08.
