42.6 MAC Modes whilst in DTM
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
42.6.1 Exclusive allocation in single-slot configuration
42.6.1.1 Conformance requirements
The exclusive allocation shall be used in dual transfer mode during single slot operation with a half-rate PDCH.
When mobile station has received the uplink assignment and granted the right to transmit using exclusive allocation, the mobile station shall start timer T3184 and transmit an RLC/MAC block in every uplink radio block on the PDCHs assigned for the TBF. The timer T3184 shall be restarted every time the mobile station receives a PACKET UPLINK ACK/NACK message.
If the mobile station has an RR connection to the network on a half-rate TCH, the network may assign a downlink TBF using the other sub-channel of the same timeslot for a half-rate PDCH (see 3GPP TS 05.02). In this case, the downlink assignment message shall be encoded with a timeslot allocation including the timeslot number for the half-rate TCH and the half-rate PDCH and only that timeslot number. The mobile station shall interpret this allocation as an allocation of a half-rate PDCH.
If the mobile station has an RR connection to the network on a half-rate TCH, the network may assign an uplink TBF using the other sub-channel of the same timeslot for a half-rate PDCH (see 3GPP TS 05.02

42.6.1.2 Test purpose
To guarantee that the MS transmits an RLC/MAC block in every uplink radio block on the PDCH assigned for the single-slot TBF, ignoring the USF indicator in the downlink radio block corresponding to the uplink PDCH/H channel.
42.6.1.3 Method of test
Initial Conditions
System Simulator:
1 cell, GPRS supported, DTM supported, PCCCH present.
Mobile Station:
The MS is in the active state (U10) of a call.
The MS is in packet idle mode, with a P-TMSI allocated and PDP context 1 activated.
Specific PICS Statements
–
PIXIT Statements
–
The MS is in a active CS call with an assigned TCH/H. The MS is triggered to initiate an uplink TBF and the MS is allocated the same timeslot for use in a uplink TBF. The MS interprets this as a command to use a combined TCH/H and exclusive mode PDCH/H in a single Timeslot. The SS verifies that the MS sends uplink RLC blocks in each block in the PDCH/H
Maximum Duration of Test
