58b.2.4a Concurrent Downlink Multi Carrier TBF / Downlink Multi Carrier Configuration / Channel Quality Reporting

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

58b.2.4a.1 Conformance requirement

In a downlink multi carrier configuration, channel quality measurements may be performed for each radio frequency channel, or each Unique Frequency Parameter Set, UFPS, independently. A UFPS is determined either by a Mobile Allocation (i.e. multiple carriers assigned the same Mobile Allocation belongs to the same UFPS), or alternatively, a fixed ARFCN. For carrier based reporting, principles that apply in Downlink Dual carrier configuration applies also for Downlink Multi Carrier configuration. For UFPS based reporting the MS shall always include channel quality measurements for the UFPS corresponding to the radio frequency channel on which the poll was received. If there is room in the message the MS may report additional UFPS (if any). Depending on the amount of information requested by the network, in case of UFPS based reporting, the MS may not be able to include channel quality measurements for all UFPSs within the applicable EGPRS PACKET DOWNLINK ACK/NACK DLMC message.

If this field indicates measurement information is to be reported on a per carrier basis the MS shall always include channel quality measurements for the carrier corresponding to the radio frequency channel on which the poll was received. If there is room in the message (see sub-clause 11.2.48) the MS shall report additional higher numbered carriers (if any) beginning with the next in sequence carrier (see sub-clause 8.1.1.1.3 for the numbering of downlink carriers in a DLMC configuration).

Test Procedure

The SS initiates the establishment of concurrent downlink multi carrier in BTTI mode. The MS is then triggered to transfer 500 octets of user data. The SS assigns an uplink TBF by sending a PACKET UPLINK ASSIGNMENT message.

While the uplink TBF is ongoing, a PACKET DOWNLINK ASSIGNMENT is sent to the MS to establish a concurrent downlink multi carrier which corresponding to uplink carrier TBF,DLMC measurement type is set to carrier based. The SS sends a RLC data blocks on downlink multi carriers that will correspond to a small RB size and poll for the First Partial Bitmap from the MS. The SS polls the MS using the ES/P field in the header of the last downlink data blocks for ES/P value = ‘11’ (EGPRS PACKET DOWNLINK ACK/NACK message containing Channel Quality Report and if there is enough room left in RLC/MAC block, NPB(s)). The SS checks if the EGPRS PACKET DOWNLINK ACK/NACK from MS includes a Channel Quality Report IE for Carrier 1 and Carrier 2.

Next the SS sends RLC data blocks on downlink multi carriers in odd BSN sequence number (bad blocks).and poll for the First Partial Bitmap from the MS pm Carrier 1. The SS polls the MS using the ES/P field in the header of the downlink data blocks for ES/P value = ‘01’ (EGPRS PACKET DOWNLINK ACK/NACK message containing FPB (First Partial Bitmap), and if there is enough room left in RLC/MAC block, channel quality report(s)). The SS checks if the EGPRS PACKET DOWNLINK ACK/NACK from MS includes a Channel Quality Report IE for Carrier 1 only.

Finally, the SS sends RLC data blocks on downlink multi carriers in odd BSN sequence number (bad blocks).and poll for the First Partial Bitmap from the MS pm Carrier 2. The SS polls the MS using the ES/P field in the header of the downlink data blocks for ES/P value = ‘10’ (EGPRS PACKET DOWNLINK ACK/NACK message containing NPB (Next Partial Bitmap), and if there is enough room left in RLC/MAC block, channel quality report(s)). The SS checks if the EGPRS PACKET DOWNLINK ACK/NACK from MS includes a Channel Quality Report IE for Carrier 2 only.
