Method for transmitting feedback data in a system of multiple antennas

Method for transmitting feedback data on a multiple antenna system, comprising the following metodolas steps of: receiving a request message feedback data on a downlink channel, comprendiendoel information request message uplink scheduling; selecting a set of M, M1, subbands in a plurality of subbands; generating feedback data; and transmitting the feedback data on a uplink channel assigned to information deplanificacion uplink, wherein the feedback data includes a PMI indicator precoding matrix, frequency selective a frequency flat PMI, CQI of best band, a quality indicator channel and unCQI full band, indicating the frequency selective PMI index matrix precodificacionseleccionada from a codebook on the M selected subbands, indicating the PMI plane enfrecuencia index matrix selected from the codebook on the plurality desubbandas indicating the best band CQI of a CQI value on the M selected subbands, and indicating full band elCQI a CQI value on the plurality of subbands precoding.
