Abstract:
1. A receiving apparatus receiving data transmitted from a transmitting apparatus in a communication system where a plurality of system bandwidths are set, said receiving apparatus comprising: a calculating unit configured to calculate, using a relationship of a CQI representing channel quality and corresponding to a transport block size of the data, a subband CQI for a subband which is a set of a predefined number of contiguous resource blocks depending on the system bandwidth, each of the resource blocks being comprised of a plurality of consecutive subcarriers in a frequency domain, and a wideband CQI for a entire system bandwidth; a generating unit configured to generate feedback information which is comprised of the subband CQI and the wideband CQI; and a transmitting unit configured to transmit the feedback information to the transmitting apparatus, wherein said calculating unit calculates a plurality of the subband CQIs for a plurality of the subbands and the wideband CQI using the same relationship, and said generating unit generates the feedback information which is comprised of the plurality of the subband CQIs and the wideband CQI, and wherein the larger the system bandwidth is, the larger the predefined number is.
