58c.1 Concurrent EGPRS2 TBF

58c.1.1a Concurrent EGPRS2A TBF using RTTI Latency reduction

58c.1.1a.1 Conformance Requirement

If a mobile station is assigned concurrent TBFs, these shall be in the same TBF mode.

A TBF in EGPRS mode operates using one of four groups of modulation and coding schemes:

– EGPRS-GMSK only (applicable to uplink TBFs only): this comprises MCS-1 to MCS-4

– EGPRS: this comprises MCS-1 to MCS-9

– EGPRS2-A: for uplink TBFs, this comprises MCS-1 to MCS-6 and UAS-7 to UAS-11; for downlink TBFs, this comprises MCS-1 to MCS-4, MCS-6 (only for retransmissions of blocks originally transmitted using EGPRS), MCS-7, MCS-8 and DAS-5 to DAS-12

– EGPRS2-B: for uplink TBFs, this comprises MCS-1 to MCS-4 and UBS-5 to UBS-12; for downlink TBFs, this comprises MCS-1 to MCS-4, MCS-6 to MCS-9, DAS-5, DAS-6, DAS-8, DAS-9, DAS-11 and DBS-5 to DBS-12.

The group of modulation and coding schemes to be used on a PDTCH associated with a TBF is indicated in the assignment message.

The use of the EGPRS2-A group for uplink or downlink is only supported by MSs which are capable of EGPRS2-A or EGPRS2-B in that direction.

If a mobile station indicates support of Reduced Latency (see 3GPP TS 24.008), it may be assigned TBFs with FANR activated (see sub-clause 9.1.14), either in BTTI configuration or in RTTI configuration. The network shall ensure that, if a mobile station is assigned a TBF with FANR activated, FANR shall be activated for all concurrent TBFs assigned to that mobile station.

GPRS, EGPRS and EGPRS2 capable mobile stations can be multiplexed dynamically on the same PDCH.

– For a mobile station supporting EGPRS2-A in the downlink, the network may use either GMSK, 8-PSK, 16-QAM or 32-QAM modulation with normal symbol rate, i.e. CS-1 to CS-4, MCS-0, MCS-1 to MCS-9 or DAS-5 to DAS-12 in those blocks.

Test Procedure

An EGPRS2A MS receives a PACKET DOWNLINK ASSIGNMENT message on its PACCH allocating resources for carrier 1. SS transmits downlink RLC data blocks. MS responds by sending a PACKET DOWNLINK ACK/NACK. MS then triggered to perform uplink data transfer in EGPRS2A to establish a concurrent uplink TBF. MS sends uplink data blocks and SS acknowledges. SS then send a PACKET TIMSLOT RECONFIGURE message to MS and to change the TTI configuration to RTTI in RTTI USF mode. A new EGPRS2A channel coding scheme is chosen for downlink. MS sends and receives data in new RTTI configuration. The uplink data transfer is completed.

58c.2.2a Acknowledged Mode/ Uplink TBF/ Retransmission/ Split RLC Data Block, in EGPRS2-A

58c.2.2a.1 Conformance requirements

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. In EGPRS2-A uplink, depending on the modulation and coding one to three RLC data blocks are contained in one RLC/MAC block as follows:

– One RLC data block per RLC/MAC block: MCS-1, MCS-2, MCS-3, MCS-4, MCS-5 and MCS-6.

– Two RLC data blocks per RLC/MAC block: UAS-7, UAS-8 and UAS-9.

– Three RLC data blocks per RLC/MAC block: UAS-10 and UAS-11.

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, UAS-7, UAS-8, UAS-9, UAS-10 or UAS-11, 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.

A TBF in EGPRS mode operates using one of four groups of modulation and coding schemes:

– EGPRS-GMSK only (applicable to uplink TBFs only): this comprises MCS-1 to MCS-4

– EGPRS: this comprises MCS-1 to MCS-9

A RESEGMENT bit is included within each PACKET UPLINK ACK/NACK, PACKET UPLINK ASSIGNMENT, MULTIPLE TBF UPLINK ASSIGNMENT, PACKET TIMESLOT RECONFIGURE, MULTIPLE TBF TIMESLOT RECONFIGURE or PACKET CS RELEASE INDICATION 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 8.1.1.1). For retransmissions, setting the RESEGMENT bit to ‘0’ (type II ARQ) requires the mobile station to use an MCS within the same family as the initial transmission without splitting the payload even if the network has commanded it to use MCS‑1, MCS‑2 or MCS‑3 for subsequent RLC blocks (refer to table 8.1.1.2), see note. In RLC unacknowledged mode, RESEGMENT bit shall be ignored and default value 0 should be used.

58c.2.5a Acknowledged Mode/ Uplink TBF/ Recalculation of CV on MCS change for EGPRS2A

58c.2.5a.1 Conformance requirements

1. The mobile station shall send the Countdown Value (CV) in each uplink RLC data block to indicate the current number of remaining RLC data blocks for the uplink TBF. The CV shall be calculated as follows:

where:

TBC = total number of RLC data blocks currently to 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 when operating in BTTI configuration. In RTTI configuration this parameter shall be equal to the number of assigned uplink PDCH pairs, with the range 1 to 4.

K =2 when commanded MCS is MCS-7, MCS-8, MCS-9, UAS-7, UAS-8, UAS-9, UBS-7 or UBS-8
3 when commanded UAS-10, UAS-11, UBS-9 or UBS-10
4 when commanded UBS-11 or UBS-12 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.

The countdown procedure starts when RLC data blocks include CV values different from ’15’. When the mobile station transmits the last RLC data block currently in the send buffer for the TBF (i.e. the RLC data block with BSN’ = TBC – 1), the RLC data block shall have CV set to the value ‘0’.

When an EGPRS or EGPRS2 RLC/MAC block for data transfer consists of two or more RLC data blocks, a CV value is calculated for each block and the CV of the RLC/MAC header refers to the last RLC data block.

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 for any untransmitted RLC data block 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. UAS-10 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 or CV =13 and ordering a change of MCS to MCS-5.

The Mobile might send a new Data Block with UAS-10 which could have been stored in the Transmit buffer.

SS notes the BSN of the last RLC data block, received with UAS-10 as BSN2. SS verifies that CV=15 till BSN=BSN2+3*CV1-15, BSN2+3*CV1-16 or BSN=BSN2+3*CV1-17 (MS can select alternate MCS)

where CV1 = CV in the last radio block received with UAS-10

SS verifies that CV decreases progressively in further blocks.

58c.2.7a EGPRS Acknowledged mode / Uplink TBF / Retransmission/ UAS or MCS Selection with Re-segmentation, in EGPRS2A

58c.2.7a.1 Conformance requirements

In EGPRS TBF mode, RLC data blocks that are transmitted for the first time shall be transmitted with the commanded MCS, 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 the case of a Downlink Dual Carrier configuration the commanded MCS shall apply to both of the carriers. 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.

For a TBF with FANR activated, if the commanded MCS is MCS-9 (respectively MCS-4), the initial transmission of the RLC data block(s) shall be done with MCS-8 (respectively MCS-3) if a PAN field is included in the radio block.

When EMST is used, the commanded MCS shall apply to the RLC entity on the TBF identified by the TFI included in the header of the RLC/MAC block.

NOTE: This bit is particularly useful for networks with uplink IR capability since it allows combining on retransmissions.

Test Procedure

The EGPRS2A 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 UAS or MCS and Resegment IE should be set to ‘0’.

The MS shall then retransmit the negatively acknowledged RLC data blocks using the UAS or MCS specified in table 8.1.1.3, 3GPP TS 44.060.

Test procedure is repeated for K = 1 to 7 with:

K = 1: UAS-11 to be used at step 1,

K = 2: UAS-10 to be used at step 1,

K = 3: UAS-9 to be used at step 1,

K = 4: UAS-8 to be used at step 1,

58c.3.4a Acknowledged Mode / Downlink TBF / Retransmission / Padding in EGPRS2-A

58c.3.4a.1 Conformance requirements

According to the link quality, an initial Modulation and Coding Scheme (MCS) is selected for an RLC block (see note). For the retransmissions, the same or another MCS from the same family of MCSs may be selected. E.g. if MCS-7 is selected for the first transmission of an RLC block, any MCS of the family B may be used for the retransmissions. Further, RLC data blocks initially transmitted with MCS-4, MCS-5, MCS-6, MCS-7, MCS-8 or MCS-9, may be retransmitted with MCS-1, MCS-2 or MCS-3 as appropriate, by sending the different parts of the RLC data block in different 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. For blocks initially transmitted with MCS-8 which are retransmitted using MCS-6 or MCS-3, padding of the first six octets shall be applied before each RLC data block, and the CPS field shall be set to indicate that this has been done (see an informative example in annex J).

Test Procedure

The SS initiates the establishment of a downlink EGPRS2-A TBF, setting window size to the largest value WS corresponding the number of timeslots assigned to TBF.

The SS sends two EGPRS2-A RLC radio blocks with BSN=0 BSN=1 and BSN=4 BSN=5 using DAS-9. In the last block FBI is set to 1 and the MS is polled for Acknowledgement.

The MS shall send a EGPRS Packet Downlink Ack/Nack type 2 message acknowledging BSNs 0,1,4 and 5 and negatively acknowledging BSN=2 and BSN=3. SS verifies that FAI is set to 0.

The SS sends EGPRS RLC data block with BSN=2 using DAS-6, setting first 6 octets of the data block to padding, and setting CPS field to indicate the same and polls the MS for acknowledgement.

The MS shall send EGPRS Packet Downlink Ack/Nack type 2 message acknowledging BSNs 0,1,2,4 and 5 and negatively acknowledging BSN=3. SS verifies that FAI is set to 0.

The SS sends first part of BSN=3 using MCS-3 with first six octets of the data block set to padding and polls the MS for acknowledgement. CPS is set correctly in the data block header to indicate that the block is first part of split block and that the data block is padded.

The MS shall send EGPRS Packet Downlink Ack/Nack message acknowledging BSNs 0,1,2,4 and 5 and negatively acknowledging BSN=3. SS verifies that FAI is set to 0.

The SS sends second part of BSN=3 using MCS-3 and polls the MS for acknowledgement. CPS is set correctly in the data block header to indicate that the block is second part of split block and that the data block is not padded.

The MS shall send EGPRS Packet Downlink Ack/Nack Type 2 message acknowledging BSNs 0 to 5. SS verifies that FAI is set to 1.

58c.3.5a Acknowledged Mode / Downlink TBF / First Partial Bitmap and Next Partial Bitmap in EGPRS2-A

58c.3.5a.1 Conformance requirements

1. In EGPRS downlink TBFs, an additional poll bit is added to the S/P field in every downlink RLC block so that the network can request the following:

– First Partial Bitmap (FPB) segment with SSN = (V(Q) + 1) mod 2048 where SSN denotes the Starting Sequence Number.

– Next Partial Bitmap (NPB) segment with SSN = (PBSN + 1) mod 2048 where PBSN denotes a Partial Bitmap Sequence Number variable stored at the receiver.

2. SSN is determined by the receiver as a function of ES/P, V(Q) and PBSN. The FPB and NPB are specific instances of the EGPRS Ack/Nack Description Information Element within the EGPRS PACKET DOWNLINK ACK/NACK message, EGPRS PACKET DOWNLINK ACK/NACK TYPE 2 message. The mobile station shall respond to ES/P field according to table 9.1.8.2.1.1 (non-MBMS). For a mobile station with one or more downlink TBFs using EGPRS2, the mobile station shall send the EGPRS PACKET DOWNLINK ACK/NACK TYPE 2 message. Otherwise, the mobile station shall send the EGPRS PACKET DOWNLINK ACK/NACK message.

3. Based on PBSN, V(Q) and the ES/P field set by the network, SSN and PBSN shall be determined according to table 9.1.8.2.2.1. For EGPRS2, SSN and PBSN shall be determined based on PBSN, V(Q) and CES/P fields according to table 9.1.8.2.2.2. For EGPRS2 the Combined EGPRS Supplementary/Polling field describes the feedback request and specifies a single uplink block in which the mobile station shall transmit a PACKET CONTROL ACKNOWLEDGEMENT message, a PACCH block see table 9.1.8.2.1.3. The single uplink block is defined by a delay relative to the first TDMA frame (N) of the downlink block containing the CES/P value. If ordered to send a EGPRS PACKET DOWNLINK ACK/NACK message or EGPRS PACKET DOWNLINK ACK/NACK TYPE 2 message, a mobile station with one or more downlink TBFs using EGPRS2 shall send the EGPRS PACKET DOWNLINK ACK/NACK TYPE 2 message. Otherwise, the mobile station shall send the EGPRS PACKET DOWNLINK ACK/NACK message.

Test Procedure

The SS establishes a downlink EGPRS2-A TBF setting EGPRS window size to 256, FANR disabled and in BTTI mode.

The SS sends a series of RLC data blocks with BSN=0, 1…5, CES/P = ‘000’B using DAS-7 coding scheme.

The SS sends a RLC data block with BSN=21, CES/P = ‘001’B and using DAS7. MS responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message with CQR and FPB within radio period (N+8 or N+9) mode 2715648.

The SS sends a RLC data block with BSN=32, CES/P = ‘010’B and using DAS-5. MS responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message with CQR and FPB within radio period (N+13) mode 2715648.

The SS sends a RLC data block with BSN=22, CES/P = ‘011’B and using DAS-6. MS doesn’t responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message.

The SS sends a RLC data block with BSN=24, CES/P = ‘100’B and using DAS-5. MS doesn’t responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message.

The SS sends a RLC data block with BSN=26, CES/P = ‘101’B and using DAS-7. MS responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message with CQR and NPB within radio period (N+8 or N+9) mode 2715648.

The SS sends a RLC data block with BSN=29, CES/P = ‘110’B and using DAS-5. MS responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message with CQR and NPB within radio period (N+13) mode 2715648.

The SS sends a RLC data block with BSN=31, CES/P = ‘111’B and using DAS-5. MS responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message with CQR and NPB within radio period (N+8 or N+9) mode 2715648.

The SS sends RLC data blocks with BSN=256, 116,241. CES/P = ‘000’B using DAS-5 coding scheme

The SS sends a RLC data block with BSN=237, CES/P = ‘111’B and using DAS-5. MS responds back with EGPRS PACKET DOWNLINK ACK/NACK TYPE2 message with no channel quality report and NPB within radio period (N+8 or N+9) mode 2715648.

Maximum Duration of Test
