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.

摘要： Provided is a base station capable of suppressing increase of overhead of allocation result report in frequency scheduling in multi-carrier communication and obtaining a sufficient frequency diversity effect. In the base station, encoding units (101-1 to 101-n) encode data (#1 to #n) to mobile stations (#1 to #n), modulation units (102-1 to 102-n) modulate the encoded data so as to generate a data symbol, a scheduler (103) performs frequency scheduling according to a CQI from each mobile station so as to uniformly allocate data to the respective mobile stations for a part of RB extracted from a plurality of RB, and an SCCH generation unit (105) generates control information (SCCH information) to report the allocation result in the scheduler (103) to the respective mobile stations.
