57.1.3.1 Conformance requirements
|
In dual transfer mode an intracell change of channel can be requested by upper layers for changing the channel type, or decided by the RR sub layer, e.g. for an internal handover or for the reallocation of all the resources of the mobile station. The purpose is to modify completely the physical channel configuration of the mobile station without frequency redefinition or change in synchronization while staying in the same cell.
Upon receipt of the DTM ASSIGNMENT COMMAND message, the mobile station initiates a local end release of link layer connections, disconnects the physical channels, commands the switching to the assigned channel and initiates the establishment of lower layer connection (this includes the activation of the channel, their connection and the establishment of the main signalling link).
NOTE: This conformance requirement was taken from Rel-5 specifications, but it is also a requirement on R99 and Rel-4 MS.

Test Procedure
Once the MS is in DTM, the SS attempts to modify the resources of the MS. The SS allocates the MS a different timeslot configuration, in the same frequency band, on the current cell. The re-allocation of the MS resources is realised by the MS receiving a DTM ASSIGNMENT COMMAND from the SS. On receipt of the DTM ASSIGNMENT COMMAND message, the MS initiates a local end release of link layer connections, disconnects the physical channels. After the MS has switched to the assigned channel, the MS initiates the establishment of lower layer connection, the activation of the channel and the establishment of the main signalling link. The MS returns an ASSIGNMENT COMPLETE message on the new signalling link.
MS supporting DTM/EGPRS shall complete testing for k=1, and indicating support of single slot DTM/EGPRS shall complete testing for k=2.

Test Procedure
An MS, in dedicated mode, is triggered to initiate uplink data transfer. The MS sends a DTM REQUEST message to the SS requesting uplink resources. The SS assigns the required resources and waits until approximately half the uplink data has been passed to the SS before instructing the MS to release the CS resources. The SS initiates the signalling required to release the channel by sending a DISCONNECT message to the MS. The MS responds to the DISCONNECT message with a RELEASE message, to which the SS responds with a RELEASE COMPLETE and then a CHANNEL RELEASE message. Once the resources have been cleared the MS requests the establishment of an uplink TBF and completes the data transmission.
MS supporting DTM/EGPRS shall complete testing for k=1 and MSs indicating support of single slot DTM/EGPRS shall additionally complete testing for k=2.

Default Initial conditions:
All default conditions, message contents and macros are defined in section 40 and section 50. If a mobile station indicates support of Reduced Latency, then an additional default initial condition used for Latred testcases in this clause is as follows. This condition is not necessary for a mobile station that does not support Reduced Latency but supports FANR only.
- Unless otherwise stated in the test case, the REDUCED_LATENCY_ACCESS bit in GPRS Cell Options is set to 1 to indicate latency reduction support by the simulator.

58a.1.1.1 Conformance Requirements
|
1. 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. If a mobile station indicates support of FANR (see 3GPP TS 24.008) and it does not indicate support of Reduced Latency, it may be assigned TBFs with FANR activated (see sub-clause 9.1.14) in BTTI configuration only.
2. The Fast Ack/Nack reporting procedure (FANR) allows to piggy-back, within EGPRS RLC/MAC blocks for data transfer sent in one direction, the acknowledgement status of data blocks relative to a TBF in the opposite direction.
3. If an uplink TBF is established or reconfigured with FANR activated (see sub-clauses 11.2.29, 11.2.29a, 11.2.31, and 11.2.31a), the mobile station shall monitor for the presence of a PAN field for this TBF on all downlink PDCHs on which it shall monitor the USF for this TBF... The network may encode the PAN field according to the SSN-based encoding defined in subclause 9.1.8 or the time-based encoding defined in subclause 9.1.15. The specific encoding selected by the network is notified to the mobile station at TBF establishment/reconfiguration.
4. When the SSN-based encoding is used (see sub-clause 9.1.14.1), the Piggy-backed Ack/Nack (PAN) field consists of a beginning of window (BOW), a short starting sequence number (ShortSSN), a reported bitmap (RB) and a temporary flow identifier (TFI) fields. In the downlink direction, the TFI field shall always include a valid value.
5. If included in a PAN field, the TFI identifies the Temporary Block Flow (TBF) being acknowledged.

Test Procedure
The MS is triggered to transfer 440 octets of user data. An uplink TBF is established. During the uplink TBF the SS negatively acknowledges one of the MS's uplink RLC data blocks using a PAN field which addresses the MS via it's TFI included in the header of a downlink data block sent on the assigned PDTCH. It is checked that the MS re-transmits the negatively acknowledged uplink RLC data block. The re-transmitted uplink RLC data block is then positively acknowledged by the SS. During the uplink TBF the SS includes a PAN field in a downlink data block sent on the assigned PDTCH which would otherwise negatively acknowledge one of the MS's uplink RLC data blocks were it not for the fact that the TFI in the PAN field addresses another MS. It is checked that the MS does not re-transmit the uplink RLC data block. The uplink RLC data block is then positively acknowledged by the SS. The uplink TBF is completed during which it is checked that the MS does not repeat any of the previously positively acknowledged uplink RLC data blocks.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

58a.1.2.1 Conformance Requirements
|
1. 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. If a mobile station indicates support of FANR (see 3GPP TS 24.008) and it does not indicate support of Reduced Latency, it may be assigned TBFs with FANR activated (see sub-clause 9.1.14) in BTTI configuration only. 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.
2. If an uplink TBF is established or reconfigured with FANR activated (see sub-clauses 11.2.29, 11.2.29a, 11.2.31, and 11.2.31a), the mobile station shall monitor for the presence of a PAN field for this TBF on all downlink PDCHs on which it shall monitor the USF for this TBF... If the presence of a PAN field is indicated in the header of an EGPRS RLC/MAC block for data transfer received on these PDCHs, the mobile station shall decode the PAN field also in the blocks addressed to other mobile stations. The network may encode the PAN field according to the SSN-based encoding defined in subclause 9.1.8 or the time-based encoding defined in subclause 9.1.15. The specific encoding selected by the network is notified to the mobile station at TBF establishment/reconfiguration.
3. When the SSN-based encoding is used (see sub-clause 9.1.14.1), the Piggy-backed Ack/Nack (PAN) field consists of a beginning of window (BOW), a short starting sequence number (ShortSSN), a reported bitmap (RB) and a temporary flow identifier (TFI) fields. In the downlink direction, the TFI field shall always include a valid value.
4. If included in a PAN field, the TFI identifies the Temporary Block Flow (TBF) being acknowledged.

Test Procedure
The MS is triggered to transfer 440 octets of user data. An uplink TBF is established. A concurrent downlink TBF is established. During the concurrent uplink and downlink TBFs, the SS negatively acknowledges one of the MS's uplink RLC data blocks using a PAN field which addresses the MS via it's TFI included in the header of a downlink data block addressed to another MS sent on the assigned PDTCH. It is checked that the MS re-transmits the negatively acknowledged uplink RLC data block. The re-transmitted uplink RLC data block is then positively acknowledged by the SS. During the concurrent uplink and downlink TBFs, the SS includes a PAN field in a downlink data block addressed to the MS sent on the assigned PDTCH which would otherwise negatively acknowledge one of the MS's uplink RLC data blocks were it not for the fact that the TFI in the PAN field addresses another MS. It is checked that the MS does not re-transmit the uplink RLC data block. The uplink RLC data block is then positively acknowledged by the SS. The downlink TBF is completed. The uplink TBF is completed during which it is checked that the MS does not repeat any of the previously positively acknowledged uplink RLC data blocks.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

58a.1.3.1 Conformance Requirements
|
1. 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. If a mobile station indicates support of FANR (see 3GPP TS 24.008) and it does not indicate support of Reduced Latency, it may be assigned TBFs with FANR activated (see sub-clause 9.1.14) in BTTI configuration only.
2. The Fast Ack/Nack reporting procedure (FANR) allows to piggy-back, within EGPRS RLC/MAC blocks for data transfer sent in one direction, the acknowledgement status of data blocks relative to a TBF in the opposite direction.
3. If an uplink TBF is established or reconfigured with FANR activated (see sub-clauses 11.2.29, 11.2.29a, 11.2.31, and 11.2.31a), the mobile station shall monitor for the presence of a PAN field for this TBF on all downlink PDCHs on which it shall monitor the USF for this TBF... The network may encode the PAN field according to the SSN-based encoding defined in subclause 9.1.8 or the time-based encoding defined in subclause 9.1.15. The specific encoding selected by the network is notified to the mobile station at TBF establishment/reconfiguration.
4. When the Time-based encoding is used (see sub-clause 9.1.14.1), the Piggy-backed Ack/Nack (PAN) field consists of a 20 bits reported bitmap, as described in sub-clause 9.1.15, plus 5 bits set to '0.

Test Procedure
The MS is triggered to transfer 1000 octets of user data. An uplink TBF is established using an EGPRS coding scheme that requires the transmission of two RLC data blocks per EGPRS uplink radio block. During the uplink TBF the SS negatively acknowledges both RLC data blocks containned within one uplink EGPRS data block sent by the MS using a PAN field in the time based format included in a downlink data block sent on the assigned PDTCH. It is checked that the MS re-transmits both negatively acknowledged RLC data blocks. The re-transmitted RLC data blocks are then positively acknowledged by the SS. During the uplink TBF the SS negatively acknowledges the first of two RLC data blocks containned within one uplink EGPRS data block sent by the MS using a PAN field in the time based format included in a downlink data block sent on the assigned PDTCH. It is checked that the MS re-transmits the negatively acknowledged RLC data block. The re-transmitted RLC data block is then positively acknowledged by the SS. During the uplink TBF the SS negatively acknowledges the second of two RLC data blocks containned within one uplink EGPRS data block sent by the MS using a PAN field in the time based format included in a downlink data block sent on the assigned PDTCH. It is checked that the MS re-transmits the negatively acknowledged RLC data block. The re-transmitted RLC data block is then positively acknowledged by the SS. The uplink TBF is completed during which it is checked that the MS does not repeat any of the previously positively acknowledged uplink RLC data blocks.

Test Procedure
The MS is triggered to transfer 440 octets of user data. An uplink TBF in RTTI mode on a single PDCH pair is established if the MS indicates support of Reduced Latency. If the MS indicates support of FANR then an uplink TBF in BTTI mode on a single PDCH is established. A concurrent downlink TBF using two PDCH (BTTI mode) or two PDCH pairs (RTTI mode), one being the same as the slot or pair used for the uplink TBF, is established. During the concurrent uplink and downlink TBFs, the SS inserts a PAN field in the SSN based format into a downlink data block transmitted on the PDCH or PDCH pair not associated with the uplink TBF but which is associated with the downlink TBF. The PAN field would otherwise negatively acknowledge one of the MS's uplink RLC data blocks and has the TFI set to the same value as assigned to the MS for it’s uplink TBF. It is checked that the MS does not re-transmit the otherwise negatively acknowledged uplink RLC data block. The uplink RLC data block is then positively acknowledged by the SS using a PAN field in the SSN based format which addresses the MS via it’s assigned uplink TFI sent on the PDCH or PDCH pair associated with the uplink TBF. The downlink TBF is completed. The uplink TBF is completed during which it is checked that the MS does not repeat any previously positively acknowledged uplink RLC data block.

58a.1.6.1 Conformance requirements
|
1. The presence of the PAN field, is signalled by the PAN indicator bit in the RLC/MAC header. When this bit is set the receiver shall use the corresponding Puncturing Scheme variant of the CPS indicated in the RLC/MAC header to decode the RLC data field.
2. For an EGPRS TBF with FANR activated, a Radio Block for data transfer consists of one RLC/MAC header, one or two RLC data block(s) and, optionally, one PAN field. It is always carried by four normal bursts. The interleaving depends on the MCS used.
3. For a TBF with FANR activated, the network may poll the mobile station to trigger the FANR procedure. In case the mobile station has at least one concurrent TBF in the uplink, the mobile station transmits, in a reserved radio block which is allocated together with polling, a radio block for data transfer including a PAN field with ack/nack information.
4. If a mobile station indicates support of Reduced Latency (see 3GPP TS 24.008), it may be assigned TBFs with FANR activated, either in BTTI configuration or in RTTI configuration. If a mobile station indicates support of FANR (see 3GPP TS 24.008), it may be assigned TBFs with FANR activated (see sub-clause 9.1.14) in BTTI configuration only. 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.
5. 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.

1. To verify that mobile station uses the received PAN field correctly for different mobile coding and puncturing schemes.
2. To verify that the MS includes the PAN field in uplink data blocks coded using different commanded MCS when polled for PAN by the network.
3. To verify that initial transmission of RLC data block(s) by MS, when PAN field is included in the radio block, shall be done with MCS-8 (respectively MCS-3) when commanded MCS is MCS-9 (respectively MCS-4).

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF, with FANR activated in the PACKET DOWNLINK ASSIGNMENT message. The MS is then triggered to transfer 5300 octets of user data, MCS-1 is used both for uplink and downlink.
After 3 uplink data blocks SS includes PAN field in the downlink data block. One uplink data block from MS is negatively acknowledged and two data blocks are positively acknowledged. MS re-transmits the negatively acknowledged data block. SS includes PAN field in the downlink data block and acknowledges the re-transmitted data block.
SS skips sending of two downlink data blocks and polls MS for acknowledgement of downlink data blocks sent. MS includes PAN field in the uplink data block and it is checked that the correct data blocks have been acknowledged.
SS re-transmits negatively acknowledged downlink data blocks and polls MS for acknowledgement of downlink data blocks sent. MS includes PAN field in the uplink data block and it is checked that the correct data blocks have been acknowledged.
Test procedure is repeated for all supported mobile coding schemes.
Maximum Duration of Test
15 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

Test Procedure
The MS is triggered to transfer 1000 octets of user data. An uplink TBF using MCS-9 on an RTTI configuration is established, if the MS indicates support of Reduced Latency. If the MS indicates support of FANR then an uplink TBF using MCS-9 on an BTTI configuration is established. A concurrent downlink TBF is established. During the concurrent uplink and downlink TBFs, the SS negatively acknowledges one of the MS's uplink RLC data blocks using a PAN field included in the header of a downlink data block. It is checked that the MS re-transmits the negatively acknowledged uplink RLC data block using MCS-6 and includes the requested PAN field in the uplink data block. The re-transmitted uplink RLC data block is then positively acknowledged by the SS. The commanded MCS is changed to MCS-4. During the concurrent uplink and downlink TBFs, the SS negatively acknowledges one of the MS's uplink RLC data blocks using a PAN field included in the header of a downlink data block. It is checked that the MS re-transmits the negatively acknowledged uplink RLC data block using MCS-1 and includes the requested PAN field in the case where re-segmentation is allowed or alternatively using MCS-4 without including the requested PAN field in the case where re-segmentation is not allowed. The re-transmitted uplink RLC data block is then positively acknowledged by the SS. The downlink TBF is completed. The uplink TBF is completed during which it is checked that the MS does not repeat any of the previously positively acknowledged uplink RLC data blocks.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (re-segmentation allowed), 2 (re-segmentation not allowed) for all MSs.

Test Procedure
The MS is triggered to transfer 1000 octets of user data. An uplink TBF is established. During the uplink TBF, the SS negatively acknowledges one of the MS's uplink RLC data blocks that it has previously positively acknowledged using a PAN field included in the header of a downlink data block. It is checked that the MS does not re-transmit the erroneously negatively acknowledged uplink RLC data block. During the uplink TBF, the SS positively acknowledges an uplink RLC data block that has not yet been transmitted at the same time as negatively acknowledging a transmitted uplink data block which has not previously been positively or negatively acknowledged using a PAN field included in the header of a downlink data block. It is checked that the MS does not re-transmit the negatively acknowledged uplink RLC data block. The uplink TBF is completed during which it is checked that the MS does not repeat any of the previously positively acknowledged uplink RLC data blocks.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF with FANR activated in the PACKET DOWNLINK ASSIGNMENT message. The MS is then triggered to transfer 440 octets of user data. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT message. The SS sends a downlink data block addressed to the MS the header of which polls the MS for PAN but which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. The SS verifies that the MS inserts a PAN field in the subsequently received uplink data block that indicates non-receipt of the downlink data blocks implied by the out of sequence BSNs.The downlink and the uplink data transfer is completed.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.

1. The Fast Ack/Nack reporting procedure (FANR) refers to the possibility to include, in a radio block for data transfer sent in one direction, piggy-backed ack/nack information relative to a TBF with FANR activated in the other direction.
2. For a TBF with FANR activated, the network may poll the mobile station to trigger the FANR procedure. In case the mobile station has at least one concurrent TBF in the uplink, the mobile station transmits, in a reserved radio block which is allocated together with polling, a radio block for data transfer including a PAN field with ack/nack information. Additionally, if enabled at TBF establishment/reconfiguration, the mobile station may initiate the FANR procedure in an event-based manner. Whenever an out-of-sequence condition is detected, or the RLC/MAC header of a radio block for data transfer is correctly received but the RLC data part is corrupted, the mobile station piggy-backs a PAN field with ack/nack information in a radio block for data transfer sent in (one of) the mobile station’s concurrent TBF(s) with FANR activated in the uplink.

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF with EVENT_BASED_FANR specified in the PACKET DOWNLINK ASSIGNMENT message. The MS is then triggered to transfer 440 octets of user data. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENTmessage. The SS sends a downlink data block which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. The SS verifies that the MS inserts a PAN field in the subsequently received uplink data block that indicates non-receipt of the downlink data blocks implied by the out of sequence BSNs. Negatively acknowledged data blocks are retransmitted.The downlink and uplink data transfer is completed.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

For EGPRS when FANR is activated or 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 or (applicable only if FANR is activated) a radio block containing a PAN field to the network, 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.
The CES/P field is used to indicate what fields the next uplink radio block reserved by this field shall contain (see further clause 9). 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. The procedures defined for transmission of a PACCH block to the network as described in sub-clause 10.4.5 shall apply.

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF with FANR activated in the PACKET DOWNLINK ASSIGNMENT message. The MS is then triggered to transfer 1000 octets of user data. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT message. While the uplink TBF is ongoing, the SS polls the MS using the CES/P field in the header of the downlink data blocks for each of the CES/P values 001 to 111.It is checked that the MS sends the correct response (according to the table in 44.060 Section 10.4.4b) to the polling in the indicated reserved block.
Following completion of the uplink TBF, the SS polls the MS using the CES/P field in the header of the downlink data blocks for each of the CES/P values 011 and 100.It is checked that the MS sends the correct response (according to the table in 44.060 Section 10.4.4b) to the polling in the indicated reserved block. Downlink data transfer is completed.
Maximum Duration of Test
20 minutes.

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF with FANR activated in the PACKET DOWNLINK ASSIGNMENT message. The MS is then triggered to transfer 1000 octets of user data, MCS-1 is used. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT message. The SS sends a downlink data block addressed to the MS the header of which polls the MS for PAN but which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. The SS verifies that the MS inserts a PAN field in the subsequently received uplink data block that indicates non-receipt of the downlink data blocks implied by the out of sequence BSNs. The user is made to initiate the establishment of a mobile originated circuit switched call. The SS sends a downlink data block addressed to the MS the header of which polls the MS for PAN but which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. The SS verifies that the MS sends PACKET CS REQUEST in the subsequently received uplink data block. The SS waits for 0.75 seconds. In the next subsequent downlink data block the MS is polled for PAN once again. The SS verifies that the MS inserts a PAN field in the subsequently received uplink data block that indicates non-receipt of the downlink data blocks implied by the out of sequence BSNs. In the next subsequent downlink data block the MS is polled once again for PAN. The SS verifies that the MS sends PACKET CS REQUEST in the subsequently received uplink data block. The SS responds with IMMEDIATE ASSIGNMENT REJECT encapsulated in the PACKET CS COMMAND. The downlink and the uplink data transfer is completed.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

The SS sends a downlink data block addressed to the MS the header of which polls the MS for PAN but which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. The SS verifies that the MS sends PACKET CELL CHANGE NOTIFICATION in the subsequently received uplink data block. The SS waits for 0.3 seconds. In the next subsequent downlink data block the MS is polled for PAN once again. The SS verifies that the MS inserts a PAN field in the subsequently received uplink data block that indicates non-receipt of the downlink data blocks implied by the out of sequence BSNs. SS resends those data blocks that were negatively acknowledged in the previous poll results. In the next subsequent downlink data block the MS is polled once again for PAN. The SS verifies that the MS sends PACKET CELL CHANGE NOTIFICATION in the subsequently received uplink data block. The SS responds with PACKET CELL CHANGE ORDER message for CellB. Now MS send CHANNEL REQUEST in the CellB. SS responds with Immediate Assignment Reject. The MS sends PACKET CELL CHANGE FAILURE in the old CellA and completes the downlink and uplink data transfer.

58a.1.17.1 Conformance Requirements
|
1. The Fast Ack/Nack reporting procedure (FANR) refers to the possibility to include, in a radio block for data transfer sent in one direction, piggy-backed ack/nack information relative to a TBF with FANR activated in the other direction.
12. If the RLC endpoint transmitter is the network and the mobile station has at least one concurrent TBF in the uplink direction, the network may poll the mobile station to trigger the FANR procedure. In this case the mobile station shall answer in a reserved radio block period which is allocated with the polling as described in sub-clause 8.1.2.2.
23. In the case where the network polls (for a PAN) and the mobile station does not have any EGPRS RLC/MAC blocks for data transfer in the uplink direction or it does not have any TBF assigned in the uplink direction, the mobile station shall transmit a EGPRS PACKET DOWNLINK ACK/NACK, EGPRS PACKET DOWNLINK ACK/NACK TYPE 2 message containing NPB, see sub-clause 10.4.4b.
3. A mobile station that detects a missing/erroneous RLC data block for a downlink TBF with FANR activated (see 3GPP TS 44.060) shall be ready to send an uplink RLC/MAC block for data transfer with a PAN or an EGPRS PACKET DOWNLINK ACK/NACK or EGPRS PACKET DOWNLINK ACK/NACK TYPE 2 message (in the case that there is no uplink RLC data ready for transmission) reflecting the missing/erroneous block in the TDMA frame indicated in Table 6.11.5.2 where N = the last TDMA frame of the downlink block in which the MS detected the problem.

1. To verify that the mobile station shall respond to polling (for a PAN) from the network by including a PAN field in a radio block belonging to a concurrent uplink TBF when a concurrent uplink TBF is established and uplink data is due to be sent.
2. To verify that the mobile station shall respond to polling for PAN by sending an EGPRS PACKET DOWNLINK ACK/NACK message containing NPB when no concurrent uplink TBF is established.
3. To verify that when responding to polling for PAN the MS adheres to the PAN reaction time requirement when a missing or erroneous data block has been detected.

Test Procedure
The SS initiates the establishment of a downlink EGPRS TBF, with FANR activated in the PACKET DOWNLINK ASSIGNMENT message. The MS is then triggered to transfer 440 octets of user data. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT message. The SS sends a downlink data block addressed to the MS the header of which polls the MS for PAN but which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. SS skips two DOWNLINK Data blocks. Then network Polls (for a PAN) the MS with CES/P in the EGPRS downlink data block. The SS verifies that the MS inserts a PAN field in the header of the subsequently received uplink data block that indicates non-receipt of the downlink data blocks implied by the out of sequence BSNs. The SS checks that the uplink data block is received within the specified PAN reaction time UPLINK RLC DATA BLOCK correctly. The Uplink data transfer is completed. SS skips one more DOWNLINK DATA BLOCKS. The network polls(for a PAN) and the MS respond in the EGPRS PACKET DOWNLINK ACK/NACK message with valid NPB. The SS sends a downlink data block addressed to the MS the header of which is correctly encoded and which polls the MS for PAN but which has a corrupted RLC data part. The SS verifies that the MS sends an EGPRS PACKET DOWNLINK ACK/NACK message that indicates non-receipt of the corrupted downlink data block. The SS checks that the EGPRS PACKET DOWNLINK ACK/NACK message is received within the specified PAN reaction time. The SS transmits the previously negatively acknowledged downlink data blocks. The SS transmits a final downlink data block addressing the MS which polls the MS for PAN. The SS checks that the MS acknowledges all of the transmitted data blocks.
Maximum Duration of Test
10 minutes.
Expected Sequence
The test case is repeated for k =1 (RTTI, single UL/DL pair), 2 (BTTI plus FANR, single UL/DL slot) for all MSs indicating support of Reduced Latency.
The test case is repeated for k =2 (BTTI plus FANR, single UL/DL slot) only for all MSs indicating support of FANR.

The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT message. The SS sends a downlink data block addressed to the MS which has a BSN that is out of sequence by two BSNs with the last downlink data block addressing the MS. The SS grants the MS it's assigned USF in a subsequent downlink data block such that the resultant uplink data block occurs at the defined PAN reaction time. It is checked that the MS includes the PAN field in the uplink data block and that the PAN field indicates non-receipt of the missing data blocks. The SS sends the negatively acknowledged data blocks to the MS. The SS grants the MS it's assigned USF in a subsequent downlink data block such that the resultant uplink data block occurs at the defined PAN reaction time. It is checked that the PAN field is not included in the resultant uplink data block. The SS sends a downlink data block addressed to the MS the header of which is correctly encoded but which has a corrupted RLC data part.

Test Procedure
The MS is triggered to transfer 1000 octets of user data. An uplink TBF with FANR on an RTTI configuration is established, if MS indicates support of Reduced Latency. If the MS indicates support of FANR, then an uplink TBF with FANR on an BTTI configuration is established. A concurrent downlink TBF with event based FANR is established. During the concurrent uplink and downlink TBFs, the SS includes the PAN field in a downlink data block which negatively acknowledges uplink data blocks sent by the MS. It is checked that the MS does not re-transmit the negatively acknowledged data blocks. All subsequent uplink data blocks are positively acknowledged by the SS by inserting PAN fields into downlink data blocks as appropriate. During the concurrent uplink and downlink TBFs, the SS omits transmission of selected downlink data blocks. Allowing for the PAN reaction time, it is checked that the MS does not include the PAN field requesting re-transmission of the missing data blocks in its subsequent uplink data blocks. During the concurrent uplink and downlink TBFs, the SS transmits downlink data blocks which have correctly encoded RLC/MAC headers but which have a corrupted RLC data part. Allowing for the PAN reaction time, it is checked that the MS does not include the PAN field requesting re-transmission of the corrupted data blocks in subsequent uplink data blocks. The downlink TBF is completed. The uplink TBF is completed.

1. Whenever the mobile station detects an assigned USF value on a monitored downlink PDCH or PDCH-pair, the mobile station shall transmit either a single RLC/MAC block or a sequence of four RLC/MAC blocks on the same PDCH or corresponding PDCH-pair for that TBF except if that TBF is running in extended uplink TBF mode, in which case the mobile station may transmit RLC/MAC block(s) for other TBFs assigned on the same PDCH or corresponding PDCH-pair (see sub-clause 9.3.1b.2). The time relation between an uplink block, which the mobile station shall use for transmission, and the occurrence of the USF value is defined in 3GPP TS 45.002. The number of RLC/MAC blocks to transmit is controlled by the USF_GRANULARITY parameter characterising the uplink TBF.
2. For an uplink TBF in RTTI configuration that receives the USFs in BTTI USF mode:
- An assigned USF received on the first PDCH of a monitored downlink PDCH-pair allocates resources for one or four uplink RTTI radio blocks in the first two TDMA frames of the following basic radio block period(s) on the corresponding uplink PDCH-pair, depending on the value of USF_GRANULARITY.
- An assigned USF received on the second PDCH of a monitored downlink PDCH-pair allocates resources for one or four uplink RTTI radio blocks in the second two TDMA frames of the following basic radio block period(s) on the corresponding uplink PDCH-pair, depending on the value of USF_GRANULARITY.

58a.2.1.2 Test Purposes
|
To verify:
1. The MS is able to operate in RTTI configuration when receiving the USF in BTTI USF mode.
2. When the mobile station receives an assigned USF on the first PDCH of the downlink PDCH-pair, it transmits uplink radio blocks in the first two TDMA frames of the following radio block period on the corresponding PDCH-pair.
3. When the mobile station receives an assigned USF on the second PDCH of the downlink PDCH-pair, it transmits uplink radio blocks in the last two TDMA frames of the following radio block period on the corresponding PDCH-pair.

Test Procedure
The SS orders the MS to have two-phase access. In PACKET UPLINK ASSIGNMENT an RTTI TBF comprising corresponding uplink and downlink PDCH-pairs is assigned to the MS. (USF_GRANURALITY is set to 1 block.) The SS sends the assigned USF on one of the PDCH of the corresponding downlink PDCH-pair assigned to the MS and checks that one RLC/MAC data block is sent in the appropriate two TDMA frames of the next radio block period. The SS assigns the USF assigned to the MS again. The check is repeated. The procedure continues until the MS completes the packet data transfer.

58a.2.2.1 Conformance Requirement
|
Whenever the mobile station detects an assigned USF value on a monitored downlink PDCH or PDCH-pair, the mobile station shall transmit either a single RLC/MAC block or a sequence of four RLC/MAC blocks on the same PDCH or corresponding PDCH-pair for that TBF except if that TBF is running in extended uplink TBF mode, in which case the mobile station may transmit RLC/MAC block(s) for other TBFs assigned on the same PDCH or corresponding PDCH-pair (see sub-clause 9.3.1b.2). The time relation between an uplink block, which the mobile station shall use for transmission, and the occurrence of the USF value is defined in 3GPP TS 45.002. The number of RLC/MAC blocks to transmit is controlled by the USF_GRANULARITY parameter characterising the uplink TBF.
For an uplink TBF in RTTI configuration that receives the USFs in RTTI USF mode:
- An assigned USF received on a monitored downlink PDCH-pair in the first reduced radio block period of a given basic radio block period allocates resources for one or four uplink RTTI radio blocks in the second reduced radio block period starting in the same basic radio block period and continuing with the second reduced radio block period in the following basic radio block periods on the corresponding uplink PDCH-pair, depending on the value of USF_GRANULARITY.
- An assigned USF received on a monitored downlink PDCH-pair in the second reduced radio block period of a given basic radio block period allocates resources for one or four uplink RTTI radio blocks in the first reduced radio block period starting in the next basic radio block period and continuing with the first reduced radio block period in the following basic radio block periods on the corresponding uplink PDCH-pair, depending on the value of USF_GRANULARITY.
On a downlink PDCH-pair assigned to a TBF in RTTI configuration with RTTI USF mode, downlink RLC/MAC control blocks shall always be encoded using either coding scheme CS-1 or coding scheme MCS-0; an MS can differentiate CS-1 blocks from MCS-0 blocks by examining the stealing bits.
