A method of transmitting feedback data in a multiple antenna system comprises receiving a request message of feedback data on a downlink channel, the request message comprising uplink scheduling information, selecting a set of M (M≧1) subbands within a plurality of subbands, generating the feedback data, the feedback data comprising a frequency selective PMI (preceding matrix indicator), a frequency flat PMI, a best band CQI (channel quality indicator) and a whole band CQI, and transmitting the feedback data on a uplink channel allocated to the uplink scheduling information. |
