WIRELESS COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, BASE STATION CONTROL PROGRAM, AND MOBILE STATION CONTROL PROGRAM

摘要

An access method, transmission power, an antenna to be used, and the number of antennas are controlled in consideration of a PH indicating a transmission power headroom. A wireless communication system which includes a base station and a mobile station and in which the mobile station performs data transmission to the base station by allocating a transmission signal converted into a frequency signal to contiguous frequency bands or non-contiguous frequency bands divided into a predetermined number, wherein, when retransmission occurs in the data transmission the mobile station has performed by allocating the transmission signal converted into the frequency signal into the non-contiguous frequency bands, the base station determines a transmission power headroom of the mobile station in the allocation of the transmission signal to the non-contiguous frequency bands, and, if a result of the determination shows that there is not a transmission power headroom, the base station instructs the mobile station to allocate the transmission signal to the contiguous frequency bands and to perform the retransmission by increasing transmission power.
