58b.2.8 Concurrent Downlink Dual Carrier TBF/ Dual Carrier Uplink TBF/ USF granularity 4

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

58b.2.8.1 Conformance requirement

In a Downlink Dual Carrier configuration, one or more PDCHs are assigned to a single mobile station on each of two different radio frequency channels. A mobile station with a Downlink Dual Carrier configuration shall not be allocated radio blocks on both radio frequency channels during any given radio block period.

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.

3GPP TS 44.060; subclause 8.1.1.1

58b.2.8.2 Test purpose

To verify that the MS:

When USF_GRANULARITY is set to four blocks allocation, MS sends uplink data blocks as per the USF_GRANULARITY parameter.

58b.2.8.3 Method of test

Initial Conditions

System Simulator:

1 cell, EGPRS supported, Downlink Dual Carrier supported.

Mobile Station:

Support for Downlink Dual Carrier indicated in MS Radio Access Capabilities IE.

The MS is in the state "idle, GMM-registered" with a P-TMSI allocated, SPLIT PG CYCLE negotiated, and PDP context 2 activated.

Specific PICS Statements

The GPRS multislot class supported (TSPC_Type_GPRS_Multislot_ClassX, where X = 1..45)

Multislot Capability Reduction for Downlink Dual Carrier of 0 or 1 Timeslots (TSPC_Type_Multislot_Capability_Reduction_for_Downlink_Dual_Carrier_of_0_or_1_Timeslots)

Multislot Capability Reduction for Downlink Dual Carrier of 2 or more Timeslots (TSPC_Type_Multislot_Capability_Reduction_for_Downlink_Dual_Carrier_of_2_or_more_Timeslots)

PIXIT Statements

Test Procedure

The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. Then MS receives a PACKET DOWNLINK ASSIGNMENT message on its PACCH, instructing a Dual Carrier Downlink configuration. MS receives an Uplink Assignment with assignment type set to Dual Carrier assignment and USF_GRANULARITY set to 4 block allocation. MS is allocated USF on carrier 1. The MS transmits 4 RLC/MAC blocks as per USF_GRANULARITY parameter. The MS is allocated USF on carrier 2. The MS transmits 4 RLC/MAC blocks on carrier 2 as per USF_GRANULARITY parameter.

Maximum Duration of Test

5 minutes.
