Abstract
A CQI control unitinputs, to a subchannel selecting unit, subchannel estimation values for report bands which are based on control information received from a control information separating unit, at report timings based on the control information. The subchannel selecting unitselects a predetermined number (M) of subchannels on the basis of the received subchannel estimation values, and inputs information indicating the selected subchannels and the qualities of the selected channels to a CQI constructing unit. Based on a predetermined format, the CQI constructing unitconstructs CQIs by using the qualities of the selected channels and the information indicating the selected channels, and inputs the CQIs to the coding unit. Here, as the channel quality, an average value of each of SNR, SINR, and CINR of subcarriers belonging to the subchannel is used. Alternatively, the poorest quality among the subcarriers included in the subchannel may be used as the channel quality of the subchannel, or information indicating the MCS required by the receiver may be used as the channel quality. In this way, it is possible to provide a method that enables the transmission of CQIs at their optimum intervals even in a case of a system using multiple discontinuous bands.
