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.
摘要翻译：一种能够选择最佳中继站，同时防止吞吐量降低的无线通信方法。根据该无线通信方法，在帧2中，中继站（1）具有等于或大于Th的线路质量，因此在中继站（2）具有线路质量的情况下，决定延迟量为Deltat1 小于Th，因此决定延迟量为Deltat2。中继站（1）使用帧2的Deltat1将中继信号发送到基站。另一方面，通过Deltat2的识别，中继站（1）使用Deltat1发送中继信号，中继站（2）停止中继信号的发送。因此，基站仅接收具有更好的线路质量的中继站（1）的中继信号。因此，当中继站（1）的线路质量优于中继站（2）的线路质量时，可以优先地发送来自中继站（1）的中继信号。

摘要： Provided is a mobile communication system capable of obtaining a diversity effect even when a signal received by a relay station has an error in a corporate relay to which time space encoding is applied. In this mobile communication system, when S1 has no error and S2 has an error, a relay station (1) does not perform relay transmission at time t (Null) and relay-transmits S1* to a base station at time t+T. That is, in this case, the relay station (1) relay-transmits at time t+T only S1 to be transmitted at time t when no error is contained in either S1 or S2. Moreover, when S1 has an error and S2 has no error, the relay station (1) relay-transmits S2 at time t and does not perform relay transmission at time t+T (Null). That is, in this case, the relay station (1) relay-transmits only S2 to be transmitted at time t+T at time t if no error is contained in either S1 or S2.

摘要： A wireless communication method capable of preventing reduction of the throughput. According to this wireless communication method, in a frame (2), a relay station (1) decides that the amount of delay to be Δt2 because the modulation scheme of a relayed signal is 16 QAM, while another relay station (2) decides that the delay amount be Δt4 because the modulation scheme of a relayed signal is QPSK. The relay station (1) transmits, at Δt2 of the frame (2), the relayed signal, the modulation scheme of which is 16 QAM, to abase station. On the other hand, the relay station (2) detects, by Δt4, the fact that the relay station (1) transmitted the relayed signal at Δt2, and estimates, from the detected fact, that the modulation scheme used by the relay station (1) was 16 QAM. The relay station (2) then updates its modulation scheme from the initially established modulation scheme of QPSK to the same modulation scheme of 16 QAM as the relay station (1), and modulates the relayed signal by use of 16 QAM and then transmits it to the base station.

摘要： A relay transmission method for communication between a base station and a mobile station via a relay station while producing a diversity effect even if the relay station detects an error in the relay signal. A decoding section (104) of the relay station used in this method performs error-correction decoding of a systematic bit by using a parity bit by repetition decoding such as turbo decoding and acquires the results of the decoding composed of the systematic bit having undergone the error-correction decoding. An error judging section (105) judges whether or not any error is present in the decoding results. Coding section (106) performs error-correction coding of the decoding results and acquires the error-correction coded systematic bit and parity bit. A selecting section (107) selects either the decoding results inputted from the decoding section (104) or a bit sequence inputted from the coding section (106) according to the result of the judgment by the error judging section (105) and outputs the selected one to a modulating section (108). A transmission control section (112) controls the operation of a radio transmitting section (109) according to the SNR of the received data symbol and the result of the judgment by the error judging section (105).
