Patent ID: 8199721

Claim:
A method for selecting a Relay Station (RS) by a Mobile Station (MS) in a communication system, comprising: measuring, by the MS, channel qualities between the MS and at least two RSs; selecting, by the MS, an RS for relaying signals between the MS and a Base Station (BS) from among the at least two RSs based on information about the measured channel qualities; and transmitting, by the MS, identification information about the selected RS to the at least two RSs, upon receiving an identification information request for the selected RS from the BS, wherein the identification information includes one of bandwidth request sequence indexes included in a bandwidth request sequence index set for the selected RS, and a Channel Quality Information (CQI) codebook for the selected RS, and wherein bandwidth request sequence index sets for the at least two RSs are the same and CQI codebooks for the at least two RSs are different, or the bandwidth request sequence index sets for the at least two RSs are different and the CQI codebooks for the at least two RSs are the same.
