MOBILE STATION DEVICE, AND UPSTREAM CIRCUIT POWER CONTROL METHOD

摘要

A mobile station device for selecting a TPC command to improve the transmission quality of a packet in an upstream circuit more reliably, so that it reduces the re-transmission in the upstream circuit to improve a sector throughput. In this mobile station device, a demodulate unit (210) outputs a received signal of each base station device to an error correction decode unit (220) and a TPC command select unit (240). The error correction decode unit (220) outputs an ACK/NACK of each base station device to a data re-transmission control unit (230) and the TPC command select unit (240). The TPC command select unit (240) selects the TPC command of the highest priority on the basis of the information of the ACK/NACK. A transmission power control unit (280) determines the transmission power according to the contents of the TPC command of the highest priority. Moreover, the transmission power control unit (280) determines the transmission power by an or-of-down method, in case a plurality of TPC commands of the highest priority are outputted from the TPC command select unit (240).
