1. In an uplink EGPRS TBF, if a compressed Reported Bitmap is received by the mobile station, the bitmap shall first be decompressed.
2. The uncompressed bitmap shall then be treated as follows:
1) Firstly, if the BOW bit is set in the Reported Bitmap, then this bitmap acknowledges all blocks between V(A) and (SSN- 2) modulo SNS, and the corresponding elements in V(B) shall be set to the value ACKED. Also a bitmap value of '0' is assumed at the bit position corresponding to (SSN-1) modulo SNS which corresponds to V(Q).
2) Then, for each bit in the uncompressed bitmap whose corresponding BSN value is within the transmit window, if the bit contains the value '1', the corresponding element in V(B) indexed relative to SSN shall be set to the value ACKED. If the bit contains the value '0', the element in V(B) shall be set to the value NACKED. A bit within the uncompressed bitmap whose corresponding BSN is not within the transmit window, shall be ignored.
3) If the EOW bit is set, assume a bitmap value of '0' for all RLC blocks with a BSN value higher than the last entry in the bitmap but less than V(S) (i.e. [ V(R) - 1 < BSN < V(S)] modulo SNS).
4) If the RLC transmitter is on the mobile station side, the bit contains the value '0' and the RLC data block was recently (re)transmitted and thus can not be validly negatively acknowledged in this particular Packet Ack/Nack message, the element in V(B) shall not modified.

When a PACKET UPLINK ACK/NACK message is received the MS shall retransmit the RLC blocks which are set to NACKED in V(B) and new RLC data blocks as far as the transmit window (if advanced) allows.
2. If a compressed reported bitmap is received, the bitmap shall first be decompressed according to Subclause 9.1.10. The uncompressed bitmap shall then be treated as follows:
3. Firstly, if the BOW bit is set in the Reported Bitmap, then this bitmap acknowledges all blocks between V(A) and (SSN- 2) modulo SNS, and the corresponding elements in V(B) shall be set to the value ACKED. Also a bitmap value of '0' is assumed at the bit position corresponding to (SSN-1) modulo SNS which corresponds to V(Q).

Then, for each bit in the uncompressed bitmap whose corresponding BSN value is within the transmit window, if the bit contains the value '1', the corresponding element in V(B) indexed relative to SSN shall be set to the value ACKED. If the bit contains the value '0', the element in V(B) shall be set to the value NACKED. A bit within the uncompressed bitmap whose corresponding BSN is not within the transmit window, shall be ignored. If the EOW bit is set, assume a bitmap value of '0' for all RLC blocks with a BSN value higher than the last entry in the bitmap but less than V(S) (i.e. [ V(R) - 1 < BSN < V(S)] modulo SNS). If the RLC transmitter is on the mobile station side, the bit contains the value '0' and the RLC data block was recently (re)transmitted and thus can not be validly negatively acknowledged in this particular Packet Ack/Nack message, the element in V(B) shall not modified. Similarly, if the RLC transmitter is on the network side and the RLC data block cannot be validly negatively acknowledged in this particular Packet Ack/Nack message the element in V(B) shall not be modified.

1. In RLC acknowledged mode, each RLC endpoint transmitter shall have an associated acknowledge state array (V(B)).
2. The transmitter shall transmit the oldest RLC data block whose corresponding element in V(B) indexed relative to V(A) has the value NACKED. As each RLC data block is transmitted the corresponding element in V(B) is set to the value PENDING_ACK.
3. Depending on the modulation and coding scheme, one or two RLC data blocks are contained in one RLC/MAC block. For MCS-7, MCS-8, MCS-9 there are two RLC data blocks in one RLC/MAC block.
4. A re-segment bit is included within each PACKET UPLINK ACK/NACK, PACKET UPLINK ASSIGNMENT and PACKET TIMESLOT RECONFIGURE message. For initial transmissions of new RLC blocks the channel coding commanded is applied. The re-segment bit is used to set the ARQ mode to type I or type II (incremental redundancy) for uplink TBFs.
5. For retransmissions, setting the re-segment bit to 1 (type I ARQ) requires the mobile station to use an MCS within the same family as the initial transmission and the payload may be split.
6. If the RLC data block to be transmitted is split over two radio blocks, both radio blocks shall be transmitted
7. RLC data blocks initially transmitted with MCS4, MCS-5, MCS-6, MCS-7, MCS-8 or MCS- 9, can optionally be retransmitted with MCS-1, MCS-2 and MCS-3 respectively, using two radio blocks. In this case, the split block field in the header shall be set to indicate that the RLC data block is split, and the order of the two parts.

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. The EGPRS Channel Coding Command IE indicates MCS-4 in the Packet Uplink Assignment message.
After BS_CV_MAX block periods the SS sends a Packet Uplink Ack/Nack message to negatively acknowledge some RLC data blocks. In the message EGPRS Channel Coding Command IE is set to MCS-1 and Re-segment IE should be set to '1'B.
The MS shall retransmit the NACKED RLC data blocks using MSC-1 in splitted radio blocks. Observe the uplink RLC data block header. Both of split blocks shall be received, the first one shall contain a SPB field equals to '10'B while the second shall be '11'B.

1. Each RLC data block contains a block sequence number (BSN) field that is 11 bits in length. At the time that an in‑sequence RLC data block is designated for transmission, the value of BSN is set equal to the value of the send state variable V(S).
2. The transfer of RLC data blocks in the RLC acknowledged mode uses retransmissions of RLC data blocks. The transmitting side numbers the RLC data blocks via the block sequence number (BSN). The BSN is used for retransmission and for reassembly. The receiving side sends PACKET Ack/Nack messages in order to request retransmission of RLC data blocks.
3. In case two RLC data blocks are sent within a RLC/MAC block, BSN2 is relative to BSN1, provided the difference between the second block number and the first block modulo SNS is less than Window Size (WS).
4. Second block sequence number = [BSN1 + BSN2] modulo SNS.

1. The mobile station shall send the Countdown Value (CV) in each uplink RLC data block to indicate to the network the absolute BSN (BSN') of the last RLC data block that will be sent in the uplink TBF. The CV shall be calculated as follows.
where:
- TBC = total number of RLC data blocks that will be transmitted in the TBF;
- BSN' = absolute block sequence number of the RLC data block, with range from 0 to (TBC - 1);
- NTS = number of timeslots assigned to the uplink TBF in the assignment message, with range 1 to 8;
- the function round() rounds upwards to the nearest integer;
- BS_CV_MAX is a parameter broadcast in the system information;
• the division operation is non-integer and results in zero only for (TBC - BSN' - 1) = 0;
• K = 2 when commanded MCS is MCS-7, MCS-8 or MCS-9, otherwise K=1.
2. If the mobile station receives a change in the Channel Coding Command in a PACKET UPLINK ACK/NACK message during the countdown procedure, the mobile station shall act upon the new Channel Coding Command. The mobile station shall then recalculate the CV values for any untransmitted RLC data blocks using the new RLC data block size.
In EGPRS TBF mode, a MS may choose an alternate MCS than the one commanded, for the initial transmission of the last RLC data blocks of the TBF under the following conditions:
- The alternate MCS is more robust than the commanded MCS;
- The alternate MCS has already been commanded by the network during the TBF or was available for selection by the MS during the TBF according to the MCS selection rules for retransmissions; and
- The TBF requires no more radio blocks for initial transmission of the RLC data blocks using the alternate MCS than would be required when using the commanded MCS.

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. The EGPRS Channel Coding Command IE indicates MCS-8 in the Packet Uplink Assignment message.
After BS_CV_MAX block periods the SS sends a Packet Uplink Ack/Nack message to negatively acknowledge some RLC data blocks. In the message EGPRS Channel Coding Command IE is set to MCS-6 or MCS-3 and Resegment IE should be set to '1'.
The MS shall then retransmit the NACKED RLC data blocks using MCS-6 or MCS-3. The SS verifies that the first 6 octets in the retransmitted RLC data blocks are padding octets and the CPS field in the RLC/MAC header indicates padding.
Maximum Duration of Test

1. In EGPRS TBF mode, RLC data blocks that are transmitted for the first time shall be transmitted with the MCS commanded, except if the commanded mode is MCS-5-7, in which case the data block shall be transmitted with MCS-5, or if the commanded mode is MCS-6-9, in which case the data block shall be transmitted with MCS-6. In EGPRS TBF mode, a MS may choose an alternate MCS than the one commanded, for the initial transmission of the last RLC data blocks of the TBF under the following conditions:
- the alternate MCS is more robust than the commanded MCS;
- the alternate MCS has already been commanded by the network during the TBF or was available for selection by the MS during the TBF according to the MCS selection rules for retransmissions; and
- the TBF requires no more radio blocks for initial transmission of the RLC data blocks using the alternate MCS than would be required when using the commanded MCS.
A re-segment bit is included within each PACKET UPLINK ACK/NACK, PACKET UPLINK ASSIGNMENT and PACKET TIMESLOT RECONFIGURE messages. For initial transmissions of new RLC blocks the channel coding commanded is applied. The resegment bit is used to set the ARQ mode to type I or type II (incremental redundancy) for uplink TBFs. For retransmissions, setting the resegment bit to '1' (type I ARQ) requires the mobile station to use an MCS within the same family as the initial transmission and the payload may be split (refer to table 1).

Test Procedure
The MS is made to transmit RLC data blocks. The SS negatively acknowledges RLC data blocks and commands the MS to use a different MCS (EGPRS Channel Coding Command). The MS retransmits the negatively acknowledged RLC data blocks and uses the commanded MCS by taking into acount the scheme specified in table 1 (see above).
Test Procedure is repeated for k = 1 to 9 with:
k=1: MCS-9 to be used at step 1,
k=2: MCS-8 to be used at step 1,
k=3: MCS-7 to be used at step 1,
k=4: MCS-6 to be used at step 1,
k=5: MCS-5 to be used at step 1,
k=6: MCS-4 to be used at step 1,
k=7: MCS-3 to be used at step 1,
k=8: MCS-2 to be used at step 1,
k=9: MCS-1 to be used at step 1.
MS NOT capable of 8PSK in Uplink should run only k=6 to 9 for step1-4 then step 30-51 with in step 30 SS acknowledging blocks BSN 0 to BSN 4 instead of only BSN 4

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. The EGPRS Channel Coding Command IE in the Packet Uplink Assignment message is set according to the execution counter K described as below.
After BS_CV_MAX block periods the SS sends a Packet Uplink Ack/Nack message to negatively acknowledge some RLC data blocks. In the message EGPRS Channel Coding Command IE is set to a different MCS and Resegment IE should be set to '0'.
The MS shall then retransmit the negatively acknowledged RLC data blocks using the MCS specified in table 8.1.1.2, 3GPP TS 04.60.
Test procedure is repeated for K = 1 to 9 with:
K=1: MCS-9 to be used at step 1,
K=2: MCS-8 to be used at step 1,
K=3: MCS-7 to be used at step 1,
K=4: MCS-6 to be used at step 1,
K=5: MCS-5 to be used at step 1,
K=6: MCS-4 to be used at step 1,
K=7: MCS-3 to be used at step 1,
K=8: MCS-2 to be used at step 1,
K=9: MCS-1 to be used at step 1.
MS NOT capable of 8PSK in Uplink should run only k=6 to 9 for step1-4 then step 31-52 with in step 31 SS acknowledging blocks BSN 0 to BSN 4 instead of only BSN 4
Maximum Duration of Test

1. The mobile station shall send the Countdown Value (CV) in each uplink RLC data block to indicate to the network the absolute BSN (BSN') of the last RLC data block that will be sent in the uplink TBF. The CV shall be calculated as follows.
where:
- TBC = total number of RLC data blocks that will be transmitted in the TBF;
• BSN' = absolute block sequence number of the RLC data block, with range from 0 to (TBC - 1);
• NTS = number of timeslots assigned to the uplink TBF in the assignment message, with range 1 to 8;
• K = 2 when commanded MCS is MCS-7, MCS-8 or MCS-9 otherwise K=1
- the function round() rounds upwards to the nearest integer;
- BS_CV_MAX is a parameter broadcast in the system information;
- the division operation is non-integer and results in zero only for (TBC - BSN' - 1) = 0.
2. If the mobile station receives a change in the Channel Coding Command in a PACKET UPLINK ACK/NACK message during the countdown procedure, the mobile station shall act upon the new Channel Coding Command. The mobile station shall then recalculate the CV values for any untransmitted RLC data blocks using the new RLC data block size.

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. MCS-6 is commanded. Total number of Data Blocks is taken to be a minimum of 20 blocks.
SS acknowledges all the Data Blocks upon reception.
SS monitors the CV of the data blocks sent.
SS sends a PACKET UL ACK/NACK message acknowledging the RLC data block with CV =14
The Mobile might send a new Data Block with MCS-6 with CV=13 which could have been stored in the Transmit buffer.
SS notes the BSN of the last data block, received with MCS6 as BSN_A and the CV as CV_A.
SS verifies that
TBC is recalculated upon MCS change by checking that CV=15 till BSN=BSN_A+2*CV_A-15 or BSN=BSN_A+2*CV_A-16 for further data blocks received after the Coding scheme change.
SS verifies that CV decreases progressively in further blocks.

If the window size is larger than the number of bits available for the bitmap, then one-dimensional run length coding (based on ITU-T T.4) is carried out starting at SSN.
If a compressed reported bitmap is received, the bitmap shall first be decompressed
Firstly, if the BOW bit in PACKET UPLINK/DOWNLINK ACK/NACK has the value "1", then the bitmap acknowledges all blocks between V(A) and (SSN- 2) (modulo SNS), and the corresponding elements in V(B) shall be set to the value ACKED. Also a bitmap value of '0' is assumed at the bit position corresponding to (SSN-1) modulo SNS which corresponds to V(Q).
Then, for each bit in the uncompressed bitmap whose corresponding BSN value is within the transmit window, if the bit contains the value '1', the corresponding element in V(B) indexed relative to SSN shall be set to the value ACKED. If the bit contains the value '0', the element in V(B) shall be set to the value NACKED. A bit within the uncompressed bitmap whose corresponding BSN is not within the transmit window, shall be ignored.
If the EOW bit in the PACKET UPLINK/DOWNLINK ACK/NACK has the value "1", , then bimap value '0' shall be assumed for all RLC blocks with a BSN value higher than the last entry in the bitmap but less than V(S) (ie. [ V(R) - 1 < BSN < V(S)] modulo SNS).

For EGPRS uplink TBFs, the network may select any composition of the Packet Ack/Nack message to send to the MS. SSN is determined by the receiver as a function of ES/P, V(Q) and PBSN.
If the receiving side is the network, the network may select any SSN within the receive window.
The BOW (begin of window) bit shall be set if SSN = [V(Q) + 1] modulo SNS, the EOW (end of window) bit shall be set if [V(R) -1] modulo SNS is explicitly included in the bitmap.
For uplink TBFs, the reported bitmap is sent using the PACKET UPLINK ACK/NACK message corresponding to the used RB size.
Firstly, if the BOW bit in PACKET UPLINK/DOWNLINK ACK/NACK has the value "1", then the bitmap acknowledges all blocks between V(A) and (SSN- 2) (modulo SNS), and the corresponding elements in V(B) shall be set to the value ACKED. Also a bitmap value of '0' is assumed at the bit position corresponding to (SSN-1) modulo SNS which corresponds to V(Q).
If the EOW bit in the PACKET UPLINK/DOWNLINK ACK/NACK has the value "1", , then bimap value '0' shall be assumed for all RLC blocks with a BSN value higher than the last entry in the bitmap but less than V(S) (ie. [ V(R) - 1 < BSN < V(S)] modulo SNS).

Test Procedure
The EGPRS capable MS is made to transmit EGPRS RLC Data Blocks in RLC acknowledged mode. Coding Scheme MCS-2 and Window Size 192 is commanded. PRE_EMPTIVE_TX is set to 1.
After receiving RLC Data block with BSN=150, SS wait for BS_CV_MAX Block periods and send PACKET UPLINK ACK/NACK with BOW=0 and EOW=0. SSN is 81 and the bitmap negatively acknowledges all blocks from BSN 81 till BSN 90 and positively acknowledges data blocks with BSN 91 till BSN 139.
SS verifies that the MS retransmit BSN 81 till BSN 90 and then transmit new data blocks. After receiving data block with BSN=160, SS wait for BS_CV_MAX Block periods and send PACKET UPLINK ACK/NACK with BOW=1 and EOW=0. SSN is set to 11 and the bitmap acknowledges data blocks with BSN 11 till BSN 75 and negatively acknowledging BSN 10, and 76 till 80.
SS verifies that MS retransmits data block with BSN 10, and BSN 76 till 80 and then continue transmitting new data blocks.
After receiving data block with BSN=170, SS wait for BS_CV_MAX Block periods and send PACKET UPLINK ACK/NACK with BOW=0 and EOW=1. SSN is 140 and the bitmap negatively acknowledges all blocks from BSN 140 till 150 and the bitmap acknowledges data blocks from BSN=151 till 170.
SS verifies that MS retransmits data blocks from BSN =140 till 150 and then continue with transmission of new data blocks.

53.1.1.25.1 Conformance requirement
|
For EGPRS the window size (WS) shall be set by the network according to the number of timeslots allocated in the direction of the TBF (uplink or downlink). The allowed window sizes are given in Table 9.1.9.2.1.
MS shall support the maximum window size corresponding to its multislot capability.The selected WS shall be indicated within PACKET UL/DL ASSIGNMENT and PACKET TIMESLOT RECONFIGURE using the coding defined in Table 9.1.9.2.1.
Once a window size is selected for a given MS, it may be changed to a larger size but not to a smaller size, in order to prevent dropping data blocks from the window.
NOTE: If a TBF is reallocated so that the number of allocated timeslots is reduced, the RLC window size may become larger than the maximum window size for the new resources.

Test Procedure
An uplink TBF allocating two timeslots is established. EGPRS Window Size is commanded to be 256 (the maximum according to the number of timeslots allocated to the TBF).
SS allocates uplink resources to the MS for transferring data in the uplink. After receiving RLC data block with BSN=191, SS sends a Packet Timeslot Reconfigure message to the MS reallocating the number of timeslots for the uplink TBF to 1.
SS allocates resources to the MS to transmit in the uplink. SS verifies that MS sends new data block with BSN=192. SS verify that MS continue to respect the initial Window Size commanded in Step 1 by checking that MS transmits new data blocks till BSN=255 and then retransmit data block with BSN=0
Maximum Duration of Test
10 minutes.

Test Procedure
The SS establishes an Uplink TBF. Uplink EGPRS Window size is commanded to be 192. When Uplink TBF is in progress, SS sends a PACKET TIMESLOT RECONFIGURE message to the MS, establishing a downlink TBF. Downlink Window Size IE is omitted from the message.
SS sends an EGPRS Downlink Data block with BSN=1 and polls the MS for acknowledgement. SS verifies that MS correctly acknowledges BSN=1.
SS sends another data block with BSN=64 and polls the MS for acknowledgement. SS verifies that MS acknowledges the data block with BSN=1 and that MS includes bitmap information only for BSN =1
SS sends a Downlink Assignment to the MS reconfiguring the Downlink Window Size to 96. SS sends some data to the MS.
SS sends a a PACKET TIMESLOT RECONFIGURE message to the MS, reconfiguring the PDCH.
Downlink Window Size IE is not included in the message.
SS sends a data block with BSN=95 and polls the MS for acknowledgement. SS verifies that MS correctly acknowledges reception of BSN=95 and that the bitmap includes information of data blocks from BSN=1 till BSN=95.

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF, setting WS = N < N' (the maximum possible legal WS value) in the PACKET DOWNLINK ASSIGNMENT message. The SS sends a RLC data block with BSN = N and polls for acknowledgement. MS shall send a Packet Downlink Ack/Nack message acknowledging no block. The MS is then triggered to transfer 440 octets of user data. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT. The SS sends an RLC data block with BSN = N-1 and polls for acknowledgement. The MS shall send a Packet Downlink Ack/Nack message acknowledging the BSN = N - 1 block.
During the downlink and uplink TBF’s, The SS sends a PACKET TIMESLOT RECONFIGURE message with WS = N'. The SS sends an RLC data block with BSN = N' and polls for acknowledgement. The MS shall send a Packet Downlink Ack/Nack message without acknowledging the BSN = N' block. The SS sends a RLC data block with BSN = N'-1 and poll for acknowledgement. The MS shall send a Packet Downlink Ack/Nack message acknowledging the BSN = N'-1 block.
Maximum Duration of Test
30 minutes.

Test Procedure
The SS establishes an acknowledge mode downlink EGPRS TBF with the MS:
1. Set the window size to the maximum value according to the number of timeslots assigned to TBF.
2. Make the FRB length shorter than the possible RB size, set the BSN sequence for transmit like 0, 2, 4, 6, 8, …, (max value of windows size), all with even values.
3. The SS sends those RLC data blocks with expected BSNs and polls the MS for the First Partial Bitmap in the last block.
4. Check the BOW bit of EGPRS PACKET DOWNLINK ACK/NACK should be '1' and the Report Bitmap should be a correct Report Bitmap.
5. The SS polls the MS for the Next Partial Bitmap.
6. Check the BOW bit of EGPRS PACKET DOWNLINK ACK/NACK should be '0' and the Report Bitmap should be a correct Report Bitmap.
7. The SS sends all of missed RLC data blocks to the MS.
Maximum Duration of Test
