Abstract
A mobile station wherein the power consumption can be suppressed. In a frame 3, this mobile station (100) transmits, to both a base station (200) and a relay station (150), a multicarrier signal comprising a plurality of subcarriers that have been controlled in transmission power on the basis of reception quality information 1 (Processes (3) and (3)′: first transmission). In a frame 4, the mobile station (100) transmits, only to the base station (200), a multicarrier signal comprising a plurality of subcarriers that have been controlled in transmission power on the basis of reception quality information 2 (Process (5): second transmission). In this case, the mobile station (100) selects subcarriers in which reception qualities indicated by the reception quality information 2 are lower than a target quality, and the mobile station (100) then transmits, to the base station (200), a multicarrier signal comprising only those subcarriers in which the reception qualities are lower than the target quality.
