58b.2.6 Concurrent Downlink Dual Carrier TBF/ Extended Dynamic Allocation
3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS
58b.2.6.1 Conformance requirement
If a mobile station supports Downlink Dual Carrier, the PACKET UPLINK ASSIGNMENT or MULTIPLE TBF UPLINK ASSIGNMENT message may assign PDCHs (corresponding to any given uplink TBF) on more than one carrier frequency. If this occurs, the Extended Dynamic Allocation procedures shall operate independently on each of the two carriers.
Reference
3GPP TS 44.060; subclause 8.1.1.2.1
58b.2.6.2 Test purpose
To verify that:
The Extended Dynamic allocation procedures work independently on each of the two carriers for a MS configured in DLDC.
58b.2.6.3 Method of test
Initial Conditions

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. 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 EXTENDED_DYNAMIC_ALLOCATION set to 1. MS is allocated USF on carrier 1. When the MS receives the assigned USF of the lowest assigned PDCH, it transmits RLC/MAC data block on the same and all higher PDCHs in the next TDMA frame. It is checked at the SS that the MS sends RLC/MAC data blocks in the next radio block period on all assigned PDTCH and that each data block contains the correct TFI without TLLI on Carrier 1. The MS is allocated USF on carrier 2. The MS transmits. RLC/MAC blocks on the TS on the same and all higher PDCHs in the next TDMA frame. The test is repeated till completion of data transfer to make sure that extended dynamic allocation works independently on each carrier.
Maximum Duration of Test
5 minutes.
