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 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： It is possible to provide a transmission control method, a radio communication system, and a radio base station device which can reduce the time required until an inter-cell interference is reduced so as to improve the system throughput. A base station (200) includes: an FFT unit (210) which receives an interference report transmitted by using a common radio resource common to adjacent cells from a plurality of radio terminals (100) existing in different adjacent cells; and an adaptive FFR processing unit (230) which controls adaptive FFR processing in a downstream line of the local cell according to the reception interference report. Thus, by receiving an interference report directly from the radio terminals (100) existing in adjacent cells, it is possible to modify the transmission mode by considering the interference state in the adjacent cells. This eliminates the need of sending a report on a transmission mode modification which has been conventionally sent between adjacent base stations (200). This reduces the signaling required in the system, which improves the system throughput.

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.
