摘要： 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.

摘要： A wireless communication method capable of selecting an optimum relay station, while preventing degradation of the throughput. According to this wireless communication method, in a frame 2, a relay station (1) has a line quality being equal to or greater than Th and hence decides that the delay amount be Δt1, while a relay station (2) has a line quality being less than Th and hence decides that the delay amount be Δt2. The relay station (1) uses Δt1 of the frame 2 to transmit a relayed signal to a base station. On the other hand, recognizing, by a lapse of Δt2, that the relay station (1) used Δt1 to transmit the relayed signal, the relay station (2) stops the transmission of the relayed signal. Accordingly, the base station receives only the relayed signal from the relay station (1) having the better line quality. Thus, when the line quality of the relay station (1) is better than that of the relay station (2), the relayed signal from the relay station (1) can be preferentially transmitted.

摘要： A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.
