<p>A receiver apparatus wherein the processing amount for CQI (Channel Quality Indicator) measurements in a communication system having a plurality of system bandwidths can be reduced. In this apparatus, a narrow band CQI measurement part measures, as a narrow band CQI, the CQI in resource blocks the number of which is required for the CQI measurement from the start position of a narrow bandwidth transmitted from a transmitter apparatus; a wide band CQI measurement part extracts, from a system bandwidth transmitted from the transmitter apparatus, resource blocks the number of which is required for the CQI measurement, and then measures, as a wide band CQI representative of the channel quality of the whole system bandwidth, an average CQI in the extracted resource blocks; and a feedback information generating part generates feedback information including both the narrow band CQI and the wide band CQI.</p> |
