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.

2. First, a Full Received Bitmap (FRB) is built from the receive state array V(N) by extracting the part between V(Q) and V(R) similar to the GPRS case: it is assigned the elements whose indices in the receive state array V(N) at the receiver range from [V(Q)+ 1] modulo SNS to [V(R) -1] modulo SNS. This global number of elements is less than WS. For each bit in the bitmap, the bit is assigned the value '1' if the corresponding element in V(N) indexed relative to SSN has the value RECEIVED. The bit is assigned the value '0' if the element in V(N) has the value INVALID.
3. The BOW bit shall be set if SSN = [V(Q) + 1] modulo SNS, the EOW bit shall be set if [V(R) -1] modulo SNS is explicitly included in the bitmap.
4. If V(Q) equals V(R), then SSN shall be set to the value SSN = [V(Q) + 1] modulo SNS, BOW bit shall be set to the value '1', EOW shall be set to the value '1' and the reported bitmap size shall equal 0 bits.

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 53.1.2.9.1 Conformance requirements | 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.

Test Procedure
SS establishes a downlink TBF allocating two timeslots. Downlink EGPRS Window Size is commanded to be 256 (the maximum according to the number of timeslots allocated to the TBF).
SS sends EGPRS RLC data block with BSN=1 on one assigned timeslot and BSN=191 in the other assigned timeslot to the MS, polling the MS for acknowledgement in the last block.
SS verifies that MS sends EGPRS PACKET DOWNLINK ACK/NACK message, positively acknowledging BSN=1 and BSN=191 and negatively acknowledging BSN=0 and all other data blocks from BSN=2 till BSN=190.
SS sends a PACKET DOWNLINK ASSIGNMENT message addressing the MS, changing the number of allocated downlink timeslots to 1.
SS sends an EGPRS RLC data block with BSN=255 on the new assigned PDCH, polling the MS for acknowledgement
SS verifies that MS sends EGPRS PACKET DOWNLINK ACK/NACK message in the assigned block period and that the received bitmap positively acknowledges blocks with BSN=1, BSN=191 and BSN=255 and negatively acknowledges BSN=0 and all blocks from BSN=2 till BSN=190 and BSN=192 till BSN=254.
