58a.2.1 Uplink RTTI TBF/ Default PDCH pair configuration/ Dynamic Allocation / BTTI USF Mode

58a.2.1.1 Conformance Requirements

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 Uplink RTTI TBF/ default PDCH pair configuration/Dynamic Allocation/ RTTI USF Mode

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.

3. When the mobile station receives an assigned USF on a monitored downlink PDCH-pair in the second reduced radio block period of a given basic radio block period it transmits 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.

Test Procedure

The MS is triggered to perform uplink packet transfer. In the PACKET UPLINK ASSIGNMENT message sent during the subsequent two phase access procedure, an RTTI mode TBF (using a single PDCH pair) using RTTI USF mode with USF GRANULARITY set to 1 block is allocated. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using CS-1 occurring in the first two TDMA frames of a given basic radio block period. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using CS-1 occurring in the last two TDMA frames of a given basic radio block period. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using MCS-0 occurring in the first two TDMA frames of a given basic radio block period. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using MCS-0 occurring in the last two TDMA frames of a given basic radio block period. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. Using a PACKET UPLINK ASSIGNMENT message, the SS re-assigns the MS the same PDTCH pair as before but changes the USF GRANULARITY to 4 blocks. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using CS-1 occurring in the first two TDMA frames of a given basic radio block period. The SS checks that the MS sends four uplink data blocks in the corresponding reduced uplink data blocks. The SS acknowledges the received data blocks. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using CS-1 occurring in the last two TDMA frames of a given basic radio block period. The SS checks that the MS sends four uplink data blocks in the corresponding reduced uplink data blocks. The SS acknowledges the received data blocks. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using MCS-0 occurring in the first two TDMA frames of a given basic radio block period. The SS checks that the MS sends four uplink data blocks in the corresponding reduced uplink data blocks. The SS acknowledges the received data blocks. The SS grants the MS the assigned USF in a reduced radio block period using a downlink control block encoded using MCS-0 occurring in the last two TDMA frames of a given basic radio block period. The SS checks that the MS sends four uplink data blocks in the corresponding reduced uplink data blocks. The SS acknowledges the received data blocks. The uplink data transfer is completed.

58a.2.5.2 Test Purposes

To verify:

1. When using BTTI USF mode, if the MS is granted the allocated USF in basic radio block period B(n) on the first of the two downlink timeslots corresponding to an uplink PDCH pair, the MS shall transmit an uplink radio block in reduced radio block period B(n+1)a occurring in the first two TDMA frames of basic radio block period B(n+1)on the uplink PDTCH pair

2. When using BTTI USF mode, if the MS is granted the allocated USF in basic radio block period B(n) on the second of the two downlink timeslots corresponding to an uplink PDCH pair, the MS shall transmit an uplink radio block in reduced radio block period B(n+1)b occurring in the last two TDMA frames of basic radio block period B(n+1) on the uplink PDTCH pair.

3. When using RTTI USF mode, if the MS is granted the allocated USF in reduced radio block period B(n)a occurring in the first two TDMA frames of basic radio block B(n) on the downlink timeslots corresponding to an uplink PDCH pair, the MS shall transmit an uplink radio block in reduced radio block period B(n)b occurring in the last two TDMA frames of basic radio block period B(n) on the uplink PDTCH pair.

4. When using RTTI USF mode, if the MS is granted the allocated USF in reduced radio block period B(n)b occurring in the last two TDMA frames of basic radio block B(n) on the downlink timeslots corresponding to an uplink PDCH pair, the MS shall transmit an uplink radio block in reduced radio block period B(n+1)a occurring in the first two TDMA frames of basic radio block period B(n+1) on the uplink PDTCH pair.

Test Procedure

The MS is triggered to perform uplink packet transfer. In the PACKET UPLINK ASSIGNMENT message sent during the subsequent two phase access procedure, an RTTI mode TBF (using a single PDCH pair) using BTTI USF mode (USF GRANULARITY set to 1 block) is allocated. The SS sends the assigned USF on the first of the two corresponding downlink PDCHs. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS sends the assigned USF on the second of the two corresponding downlink PDCHs. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS checks on each timeslot that the MS does not respond to USF grants using the USF allocated to the other timeslot. Using a PACKET UPLINK ASSIGNMENT message, the SS changes the USF mode (from BTTI mode to RTTI USF mode). The SS grants the MS the assigned USF in a reduced radio block period occurring in the first two TDMA frames of a given basic radio block period. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS grants the MS the assigned USF in a reduced radio block period occurring in the last two TDMA frames of a given basic radio block period. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS checks that the MS no longer responds to the USFs previously allocated in BTTI USF mode. Using a PACKET TIMESLOT RECONFIGURE message, the SS changes the USF mode (from RTTI mode to BTTI USF mode). The SS sends the assigned USF on the first of the two corresponding downlink PDCHs. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS sends the assigned USF on the second of the two corresponding downlink PDCHs. The SS checks that the MS sends one uplink data block in the corresponding reduced uplink data block. The SS acknowledges the received data block. The SS checks that the MS does not respond to USF grants using the USF previously allocated in RTTI USF mode. The uplink data transfer is completed.

58a.2.6 Uplink RTTI TBF / One Phase Access Request by Reduced Latency MS / CCCH Case / Contention Resolution

58a.2.6.1 Conformance requirements

EGPRS TBF mode capable mobile stations shall monitor the GPRS Cell Options IE on the BCCH (SI13) for the cell’s EGPRS capability and, if the mobile station is also Reduced Latency capable, the cell’s Reduced Latency Access capability. In the GPRS Cell Options IE it is also indicated if the EGPRS PACKET CHANNEL REQUEST message is supported in the cell and if Reduced Latency Access is supported in the cell. The following table specifies which message and which establishment cause shall be used by an EGPRS mobile station when accessing an EGPRS capable cell depending on the purpose of the packet access procedure, and mobile station’s and cell’s capabilities; this table covers the case where PBCCH is not present in the cell (see 3GPP TS 44.060 for the case where PBCCH is present in the cell).

Purpose of the packet

EGPRS PACKET CHANNEL REQUEST supported in the cell

EGPRS PACKET CHANNEL

REQUEST not supported in the cell

User data transfer –

requested RLC mode = acknowledged (Reduced Latency supported by MS)

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request by Reduced Latency MS’ (NOTE 2)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

NOTE 2: The One phase Access Request by Reduced Latency MS shall be used by the mobile station supporting reduced latency if Reduced Latency Access is supported by the network.

In the case of an uplink EGPRS TBF assignment in RTTI configuration where an IMMEDIATE ASSIGNMENT message is sent in response to a one phase access with access type indicating "One Phase Access Request by Reduced Latency MS" as defined in 3GPP TS 44.060, the assigned timeslots of the uplink PDCH pair(s) and the corresponding downlink PDCH pair (as defined in 3GPP TS 44.060) associated with each assigned uplink PDCH pair are indicated by a combination of the TN given by the Packet Channel Description information element and information in the EGPRS Packet Uplink Assignment construction of the IA Rest Octets information element as described in sub-clause 10.5.2.16.

The contention resolution is successfully completed on the mobile station side when the mobile station receives a PACKET UPLINK ACK/NACK message addressing the mobile station with the TFI value associated with the uplink TBF and including the same TLLI value that the mobile station has included in the RLC header of the first RLC data blocks, or alternatively, in EGPRS TBF mode, a PACKET UPLINK ASSIGNMENT message addressing the mobile station with the TFI value associated with the uplink TBF and including the same TLLI value that the mobile station included in the RLC header of the first RLC data blocks. The mobile shall then stop timer T3166 and counter N3104.

Upon contention resolution during one phase access, the mobile station shall start transmitting RLC data blocks without the TLLI field as follows:

– For a TBF operating in RTTI configuration, no later than the next occurrence of block B((x+2) mod 12)_b where block Bx_a is the radio block containing the contention resolution message or no later than the next occurrence of block B((x+3) mod 12)_a where block Bx_b is the radio block containing the contention resolution message (see 3GPP TS 45.002 [10] for an explanation of RTTI radio block indexing applicable to the RTTI configuration).

Test Procedure

The MS is triggered to initiate uplink data transfer. Following reception of the EGPRS PACKET CHANNEL REQUEST message, the SS assigns an uplink TBF in RTTI mode on a single PDTCH pair using an IMMEDIATE ASSIGNMENT message. The SS checks that the MS includes the TLLI in the initial uplink data blocks received on the assigned resources. The SS sends a PACKET UPLINK ASSIGNMENT message allocating the same uplink resources as in the previous IMMEDIATE ASSIGNMENT message, but including the contention resolution TLLI. The SS checks that the MS ceases to include the TLLI in the header of the subsequent uplink data blocks within the reaction time defined. The uplink TBF is completed.

Test Procedure

The assigned downlink resources are reassigned so that the downlink TBF uses a single PDCH pair on contiguous timeslots different to those used by the corresponding downlink PDCH pair of the uplink TBF. The assigned uplink resources (uplink PDCH pair and corresponding downlink PDCH pair) remain unchanged. The MS includes a Channel Quality Report IE in EGPRS PACKET DOWNLINK ACK/NACK message. It is checked that the MS responds to polling for downlink ack/nack on the new downlink PDCH pair. It is checked that the MS responds to USF grant on the downlink PDCH pair corresponding to the uplink PDCH pair. It is checked that the MS reports on the correct _TNx.

The assigned downlink resources are reassigned so that the downlink TBF uses a single PDCH pair on non-contiguous timeslots different to those used by the corresponding downlink PDCH pair of the uplink TBF.

58a.2.8 Downlink RTTI TBF / default PDCH pair configuration/CCCH case

58a.2.8.1 Conformance requirements

The network initiates the packet downlink assignment procedure by sending an IMMEDIATE ASSIGNMENT message in unacknowledged mode on the CCCH timeslot corresponding to CCCH group the mobile station belongs to.

On receipt of an IMMEDIATE ASSIGNMENT message or, in case of a two-message assignment, a matching pair of IMMEDIATE ASSIGNMENT messages, the mobile station stops monitoring downlink CCCH and switches to the assigned PDCH and starts listening for downlink RLC/MAC blocks identified by the assigned TFI; it starts timer T3190.

In case RTTI configuration is supported by the network and the mobile station and a downlink TBF operating in RTTI configuration is assigned, the following parameters shall be provided by the network in the assignment message (e.g. PACKET DOWNLINK ASSIGNMENT, MULTIPLE TBF DOWNLINK ASSIGNMENT, PACKET TIMESLOT RECONFIGURE, MULTIPLE TBF TIMESLOT RECONFIGURE or PACKET CS RELEASE INDICATION).

– a Temporary Flow Identity (TFI). The TFI applies to all radio blocks transferred in regards to the downlink Temporary Block Flow (TBF);

– one or more downlink PDCH-pairs to be used for the downlink transfer;

58a.2.9 Concurrent RTTI TBFs / Explicit PDCH Pair Configuration

58a.2.9.1 Conformance Requirement

If the default single carrier PDCH pair configuration is indicated, then the assignment is for resources on a subset of the PDCH pairs comprising timeslots 0 and 1, 2 and 3, 4 and 5, and 6 and 7 in both the uplink and on the downlink. If the default dual carrier PDCH pair configuration is indicated, then the assignment is for resources on a subset of the PDCH pairs comprising timeslots 0 and 1, 2 and 3, 4 and 5, and 6 and 7 on both carriers in both the uplink and on the downlink. Otherwise, the assignment is for resources on a subset of the PDCH pairs as specified in the Downlink_PDCH_Pairs_C1, Downlink_PDCH_Pairs_C2, Uplink_PDCH_Pairs_C1 and Uplink_PDCH_Pairs_C2 bitmaps.

If the mobile station is currently in packet transfer mode with one or more RTTI TBFs ongoing, then the network may indicate in the assignment message that the PDCH pair configuration is ‘Unchanged’. In this case, the PDCH pair configuration described in the most recently received assignment message (for this mobile station) previous to this message applies.

For an uplink PDCH pair using timeslots i and j, where j > i , the corresponding downlink PDCH pair is:

– the one using timeslots i and j; else, if no such PDCH pair is specified

– the one using timeslots i-1 and i; else, if no such PDCH pair is specified

– the one using timeslots i-2 and i; else, if no such PDCH pair is specified

– the one using timeslots i-3 and i if such a PDCH pair exists.

In case the uplink TBF operates in RTTI configuration then the network shall transmit all PACCH messages on the corresponding downlink PDCH-pair associated with the lowest numbered assigned uplink PDCH-pair. Additionally, for the concurrent TBF case, the network may transmit PACCH messages on any of the PDCH-pairs assigned that are common to the downlink and uplink PDCH-pair assignments.

Test Procedure

The MS is triggered to perform uplink packet transfer. An RTTI mode uplink TBF using RTTI USF mode on a single PDCH pair having contiguous timeslots is assigned. It is checked that the MS responds to USF grant on the corresponding downlink PDCH pair. A downlink RTTI mode TBF using a single PDCH pair having the same timeslots as the corresponding downlink PDCH pair of the uplink PDCH pair is assigned. It is checked that the MS responds to polling for PAN on the assigned downlink PDCH pair. The assigned downlink resources are reassigned so that the downlink TBF uses a single PDCH pair on contiguous timeslots different to those used by the corresponding downlink PDCH pair of the uplink TBF. The assigned uplink resources (uplink PDCH pair and corresponding downlink PDCH pair) remain unchanged. It is checked that the MS responds to polling for downlink ack/nack on the new downlink PDCH pair. It is checked that the MS responds to USF grant on the downlink PDCH pair corresponding to the uplink PDCH pair. The assigned downlink resources are reassigned so that the downlink TBF uses a single PDCH pair on non-contiguous timeslots different to those used by the corresponding downlink PDCH pair of the uplink TBF. The assigned uplink resources (uplink PDCH pair and corresponding downlink PDCH pair) remain unchanged. It is checked that the MS responds to polling for downlink ack/nack on the new downlink PDCH pair. It is checked that the MS responds to USF grant on the downlink PDCH pair corresponding to the uplink PDCH pair. The assigned downlink resources are reassigned so that the downlink TBF uses a single PDCH pair on contiguous timeslots. At the same time the uplink resources are reassigned to use a single PDCH pair on non-contiguous timeslots that are different to those used by the corresponding uplink pair of the assigned downlink PDCH pair. It is checked that the MS responds to polling for downlink ack/nack on the new downlink PDCH pair at which time the downlink TBF is terminated. It is checked that the MS responds to USF grant on the downlink PDCH pair corresponding to the new uplink PDCH pair. The uplink TBF is completed.

58a.2.10 Concurrent RTTI TBF / Change in TTI configuration

58a.2.10.1 Conformance requirements

The network may, at any time during downlink packet transfer, change the TTI configuration of an already established downlink TBF by sending on the downlink PACCH a downlink TBF assignment message (e.g. PACKET DOWNLINK ASSIGNMENT, MULTIPLE TBF DOWNLINK ASSIGNMENT, PACKET TIMESLOT RECONFIGURE, MULTIPLE TBF TIMESLOT RECONFIGURE or PACKET CS RELEASE INDICATION). In case of a TTI configuration change the mobile station shall begin using the new TTI configuration within the reaction time defined in 3GPP TS 45.010.

An MS shall be ready to transmit and receive using a new assignment 9 frame periods after the last radio block containing the assignment message. A mobile station that receives an assignment message for a new or ongoing TBF with FANR activated (see 3GPP TS 44.060) shall be ready to transmit and receive using the new assignment in the TDMA frame indicated in Table 6.11.1.1 where N = the last TDMA frame of the downlink block containing the assignment message.

Test Procedure

The MS is triggered to perform uplink packet transfer. A BTTI uplink TBF is established and in progress. After the MS sends an uplink data block the SS assigns a downlink TBF on the same timeslot as the uplink TBF. The SS sends a downlink data block with polling for acknowledgement and the assigned USF assigned to the MS for the MS, and indicates FBI=1 for the final data block. The MS sends an uplink data block and acknowledges the received downlink data block on the correct frame.

An RTTI mode uplink TBF using RTTI USF mode on a single PDCH pair having contiguous timeslots is assigned by a PACKET UPLINK ASSIGNMENT message (to change TTI configuration from BTTI to RTTI). It is checked that the MS responds to USF grant on the corresponding downlink PDCH pair. A downlink RTTI mode TBF using a single PDCH pair having the same timeslots as the corresponding downlink PDCH pair of the uplink PDCH pair is assigned. It is checked that the MS responds to polling for PAN on the assigned downlink PDCH pair.

The SS sends PACKET TIMESLOT RECONFIGURE (to change TTI configuration from RTTI to BTTI) assigning a new downlink PDCH replacing the previous PDCH-pair assignment. A downlink data block is sent, the assigned USF assigned to the MS and the MS is polled for acknowledgement. The MS sends an uplink data block and acknowledges the last received downlink data block on the correct frame.

The SS sends PACKET TIMESLOT RECONFIGURE (to change TTI configuration from BTTI to RTTI) assigning a new downlink PDCH-pair replacing the previous PDCH assignment. An RTTI mode uplink TBF using RTTI USF mode on a single PDCH pair having contiguous timeslots is assigned. A downlink RTTI mode TBF using a single PDCH pair having the same timeslots as the corresponding downlink PDCH pair of the uplink PDCH pair is assigned. It is checked that the MS responds to polling for downlink ack/nack on the newly assigned downlink PDCH pair corresponding to the new uplink PDCH pair. The uplink TBF is completed.

58a.2.11 Concurrent RTTI TBF / Downlink Dual Carrier configuration

58a.2.11.1 Conformance requirements

If the default dual carrier PDCH pair configuration is indicated, then the assignment is for resources on a subset of the PDCH pairs comprising timeslots 0 and 1, 2 and 3, 4 and 5, and 6 and 7 on both carriers in both the uplink and on the downlink. Otherwise, the assignment is for resources on a subset of the PDCH pairs as specified in the Downlink_PDCH_Pairs_C1, Downlink_PDCH_Pairs_C2, Uplink_PDCH_Pairs_C1 and Uplink_PDCH_Pairs_C2 bitmaps.

For the purposes of interpreting the RTTI_DOWNLINK_PDCH_PAIR_ASSIGNMENT_SC and RTTI_DOWNLINK_PDCH_PAIR_ASSIGNMENT_DC bitmaps and the repeated USF structures in the Dynamic Allocation 2 struct and Uplink TBF Assignment 2 struct, PDCH pairs are ordered starting with the PDCH pair on carrier 1 using the lowest numbered timeslots, followed by the PDCH pair on carrier 1 using the next lowest numbered timeslots and so on, followed by the PDCH pair on carrier 2 using the lowest numbered timeslots (if present), etc.

For an uplink PDCH pair using timeslots i and j, where j > i , the corresponding downlink PDCH pair is:

– the one using timeslots i and j; else, if no such PDCH pair is specified

– the one using timeslots i-1 and i; else, if no such PDCH pair is specified

– the one using timeslots i-2 and i; else, if no such PDCH pair is specified

– the one using timeslots i-3 and i if such a PDCH pair exists.

When a mobile station has resources assigned on only one carrier then, for the purposes of subsequent assignment messages, that carrier shall be considered carrier 1. A subsequent assignment message may assign resources on a second carrier, thereby establishing a Downlink Dual Carrier configuration; in this case, the assignment message shall provide frequency parameters for a second carrier (carrier 2) for use in a Downlink Dual Carrier configuration.

Downlink Dual Carrier enables downlink TBFs and uplink TBFs to use allocated resources on one or more assigned PDCHs on two different radio frequency channels. Uplink RLC/MAC blocks shall not be scheduled on both carriers of a downlink dual carrier configuration in the same radio block period. Downlink RLC/MAC blocks may be scheduled on both carriers of a downlink dual carrier configuration in the same radio block period.

Test Procedure

The MS is triggered to initiate uplink data transfer. Following reception of the EGPRS PACKET CHANNEL REQUEST message, the SS assigns an uplink TBF in RTTI mode on a single PDTCH pair using an IMMEDIATE ASSIGNMENT message. The MS is then made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. SS sends a PACKET DOWNLINK ASSIGNMENT message on its PACCH, instructing the MS for a Dual Carrier Downlink configuration. The SS sends RLC data blocks on Carrier 1 and Carrier 2 simultaneously. MS when polled acknowledges all data blocks send by SS. This is to setup Concurrent Downlink Dual Carrier TBF. The SS sends RLC data blocks on Carrier 1 and Carrier 2 simultaneously. The MS receives PACKET UPLINK ASSIGNMENT messages to establish one uplink TBFs with resources on both carrier 1 and carrier 2. MS when polled acknowledges all data blocks send by SS. The MS receives PACKET TIMESLOT RECONFIGURE message on its PACCH to establish single carrier in both downlink and uplink and change the configuration from RTTI to BTTI mode. Also the assigned downlink PDCH pairs are non-contiguous. The SS sends MS a PACKET DOWNLINK DUMMY CONTROL BLOCK in BTTI mode and assigns the USF. The MS sends an EGPRS UPLINK RLC DATA BLOCK to the SS.

The MS receives another PACKET TIMESLOT RECONFIGURE message to change the configuration back to Dual Carrier in BTTI mode. Repeat step 21 to step 28 until the completion of data transfer.

If the MS is of EGPRS multislot class 30-39, steps 30-31 should be executed after step 29.

58a.2.12 Concurrent RTTI TBF / Dual Transfer Mode

58a.2.12.1 Conformance requirements

The RR connection establishment procedure is initiated by the RR entity of the mobile station. Initiation is triggered by request from the MM sublayer to enter dual transfer mode. The request from the MM sublayer to establish the RR connection specifies an establishment cause.

While in dedicated mode, the establishment of an uplink packet resource may be initiated by the RR entity of the mobile station using the packet request procedure.

The mobile station initiates the establishment the packet resource by sending a DTM REQUEST message on the main DCCH.

On receipt of a DTM REQUEST message the network may allocate an uplink packet resource. The packet uplink resource is assigned to the mobile station in one of the DTM assignment messages:

– DTM ASSIGNMENT COMMAND; or

– PACKET ASSIGNMENT.

These messages are sent in acknowledged mode. The DTM ASSIGNMENT COMMAND message may be sent on the SDCCH and on the FACCH. The PACKET ASSIGNMENT message shall be sent only on FACCH.

When sending the DTM ASSIGNMENT COMMAND message on the network side, and when receiving it on the mobile station side, all transmission of signalling layer messages except for those RR messages needed for this procedure and for abnormal cases is suspended until resumption is indicated.

The PACKET ASSIGNMENT message is only used when the packet resource is a PDCH and no reallocation of the RR connection is needed.

The mobile station remains in dual transfer mode until the RR connection or all the packet resources are released.

Reference

3GPP TS 44.060 v9.0.0, subclause 8.9

3GPP TS 44.018, subclause 3.4.22, 3.4.23

All of the above requirements shall be met while maintaining Concurrent RTTI TBF.

58a.2.12.2 Test purpose

To verify that the MS is able to operate a RTTI TBF in Dual Transfer Mode with DTM Command message. The following parts are verified:

MS is in active state of a call and MS initiates the data.

MS is in active state of a call and the network initiates the data.

MS is in a packet transfer mode and user is made to initiate the establishment of a mobile originated circuit switched call.

Test Procedure

This part tests the DTM ASSIGNMENT COMMAND message. Reallocation of the RR connection is needed while assigning the packet resources.

Once the MS is in state U10 utilising the default TCH of the cell, the MS is triggered to transfer 10000 octets of user data. MS send DTM REQUEST message indicating the supports for Reduced Latency Capability. SS send a DTM ASSIGNMENT COMMAND to the MS to change the channel configuration to a configuration with CS and packet connections when no timing adjustment is needed and reallocation of the CS timeslot is required. MS replies back with ASSIGNMENT COMPLETE message.

The MS starts to send RLC DATA BLOCKS to the SS on the assigned PDTCH. The network also starts to send RLC data blocks to the MS. The test procedure is complete when the SS successfully verifies both uplink and downlink transmission are working in parallel. Finally the CS connection is released.

Steps 12-20 tests the PACKET ASSIGNMENT COMMAND message. The packet resource is a PDCH and no reallocation of the RR connection is needed.

Steps 1-11 are repeated except that in this case the SS send a PACKET ASSIGNMENT to the MS upon receipt of the DTM request message from the MS. There is no ASSIGNMNET COMPLETE message sent back to the SS.

Next the MS is in a dedicated mode and the network initiates data transfer. Steps 21-28 tests the DTM ASSIGNMENT COMMAND message. Reallocation of the RR connection is needed while assigning the packet resources. In step 21 the MS in the active state (U10) of a call on Timeslot N. in step 22 the network initiates transfer of 10000 octets of data by sending a DTM ASSIGNMENT COMMAND message. The MS replies back with an ASSIGNMENT COMPLETE message. Concurrent TBF’s is established and the data is transferred in both uplink and downlink. The SS verifies that both uplink and downlink data transmission is functioning correctly. The SS also verifies that the CS connection is still through connected. Finally the SS releases the CS connection.

In step 29 the MS is again triggered to transfer 10000 octets of user data. Steps 29-35 tests the PACKET ASSIGNMENT COMMAND message. The packet resource is a PDCH and no reallocation of the RR connection is needed.

Steps 36-57 correspond to the concurrent RTTI TBF establishment in the enhanced DTM CS establishment procedure.

The MS is brought into packet transfer mode for uplink TBF. The user is made to initiate the establishment of a mobile originated circuit switched call. The MS sends the PACKET CS REQUEST message on PACCH. The NW responds by sending an encapsulated DTM ASSIGNMENT COMMAND on the PACCH. Upon receipt of the PACKET CS COMMAND, the MS initiates the establishment of the CS connection. It is checked that the MS maintains the uplink TBF throughout the enhanced DTM CS establishment procedure.
