58b.2.2 Concurrent Downlink Dual Carrier TBF/ Change in Modulation and Coding Schemes

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

58b.2.2.1 Conformance requirement

In the case of a Downlink Dual Carrier configuration the commanded MCS shall apply to both of the carriers.

References

3GPP TS 44.060; subclause 8.1.1

58b.2.2.2 Test purpose

To verify that the MS is able to operate in different modulation and coding schemes while operating in a downlink dual carrier configuration on different carrier.

58b.2.2.3 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.

Test Procedure

The downlink blocks on C1 will be cycled through all valid MCS combinations. The SS asks for an acknowledgement from the MS. The MS shall correctly acknowledge all the received data blocks.

The downlink blocks on C2 will be cycled through all valid MCS combinations. The SS asks for an acknowledgement from the MS. The MS shall correctly acknowledge all the received data blocks.

The downlink blocks on both carriers will be cycled through all valid MCS combinations. The SS asks for an acknowledgement from the MS. The MS shall correctly acknowledge all the received data blocks.

The MS will be ordered to cycle through different MCS in the UL direction. The SS verifies the correct MCS is used. The SS shall correctly acknowledge all the received data blocks.

Maximum Duration of Test

10 minutes.
