摘要： Provided is a radio communication method or the like for making compatible an improvement in error rate characteristics and a reduction in delay. The radio communication method is used in a mobile communication system including a mobile station, a relay station and a base station. A transmitted signal containing a signal addressed to the base station is transmitted at first from the mobile station to the relay station. A non-reproduced relay signal obtained in the relay station from the transmitted signal is transmitted from the relay station to the base station. On the basis of the reception result of the non-reproduced relay signal at the base station, a re-transmission request of the transmitted signal is transmitted from the base station. A reproduced relay signal, as obtained from the transmitted signal in the relay station, is transmitted from the relay station to the base station in accordance with the re-transmission request transmitted from the base station.

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.
