58b.2.7a Concurrent Downlink Multi Carrier TBF / Downlink Multi Carrier Configuration/ Extended RLC/MAC control message segmentation

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

58b.2.7a.1 Conformance requirement

extended RLC/MAC control message segmentation as defined in sub-clause 9.1.12a.

In the case of a Downlink Dual Carrier configuration or a DLMC configuration, all segments belonging to each RLC/MAC control message shall be sent on PACCH blocks belonging to the same carrier.

The network may segment RLC/MAC control messages into one, two or up to nine RLC/MAC control blocks depending on the length of the RLC/MAC control message. Segmentation of an RLC/MAC control message into more than two RLC/MAC control blocks is referred to as extended RLC/MAC control message segmentation. Extended RLC/MAC control message segmentation shall not be used for an RLC/MAC control message that can be sent using one or two RLC/MAC control blocks. Unless explicitly stated otherwise, extended RLC/MAC control message segmentation shall not be used. If the contents of a control message do not fit an integer number of control blocks, filler octets shall be used to fill the remainder of the RLC/MAC control block. Only the last RLC/MAC control block containing elements of the control message shall contain filler octets.

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, segmented in 3 blocks , instructing a Multi Carrier Downlink configuration. The MS must do a re assembly of the received block and switch to the assigned PDCH. The SS sends RLC data blocks on Carrier 1 and Carrier 2 simultaneously. MS when polled acknowledges all data blocks send by SS.

While the MS has a concurrent TBF established, the SS sends a PACKET DOWNLINK ASSIGNMENT that assigned a new TFI value. The PACKET DOWNLINK ASSIGNMENT is segmented in 3 RLC control block but the final segment with FSe bit and RBSNe set to 1. The SS sends RLC data blocks on Carrier 1 and Carrier 2 simultaneously with the new assigned TFI; the tester checks that the MS does not answer with an EGPRS PACKET DOWNLINK ACK/NACK.

The SS sends RLC data blocks on Carrier 1 and 2 with TFI assigned in step 5. MS when polled acknowledges all data blocks send by SS and complete the uplink data transfer.

Maximum Duration of Test

10 minutes.
