Abstract
A communication apparatus wherein in a case of reporting a reception quality measured for each of a plurality of subbands, even if the band is widened, the degradation in transmission efficiency can be avoided. In this apparatus, an antenna () receives the pilot signals superimposed on a plurality of subbands in a predetermined band. A quality level calculating unit () uses the received pilot signals to measure the reception qualities of the respective subbands. A CQI selecting unit () selects one of a plurality of CQI values that corresponds to one of the measured reception qualities for each subband. A feedback information generating unit () calculates a first average value of the selected CQI values, calculates a second average value of the CQI values indicating better reception qualities than the first average value, and calculates a difference value between the second average value and each of the CQI values indicating better reception qualities than the second average value. A transmitting unit () transmits, as feedback information, the first and second average values and the difference values to the other end of communication.
