摘要： A method of transmitting precoding information in a multiple antenna system includes selecting M subbands from a plurality of subbands constituting a whole frequency band in a descending order of a channel quality indicator (CQI), where M is an integer satisfying M>0, and transmitting a first precoding matrix indicator (PMI) for the M subbands and a second PMI for a remaining band, wherein the first PMI is a PMI of a codebook selected from a first codebook set including a plurality of codebooks and the second PMI is a PMI of a codebook selected from a second codebook set including a part of the plurality of codebooks of the first codebook set. Accordingly, precoding information can be effectively transmitted by separately preparing a codebook for a best band and a codebook for a non-selected band.

摘要： Disclosed is a method for efficiently transceiving information required for implementing a multi-cell-based CoMP MU-MIMO scheme. For this purpose, a base station which performs CoMP operation generates: (A) a reference signal sequence on the basis of a specific base station; or generates (B) the same reference signal sequence on the basis of a CoMP ID, and transmits the generated sequence to user equipment. To support an MU-MIMO scheme and to perform a joint processing method, the base station must additionally transmit CoMP reference signal sequence information, frequency shift information, etc. to the user equipment in said (A) case, and generates a CoMP reference signal on the basis of a preset CoMP set ID and transmits the generated signal to the user equipment in said (B) case.
