A mobile station apparatus selects an appropriate one of transmission rate instruction commands received from base station apparatuses to reduce the interference of the whole system and improve the sector throughput. In this mobile station apparatus ( 200 ), a demodulating section ( 210 ) outputs a received signal of each base station apparatus to an error correction decoding section ( 220 ), which then outputs the ACK/NACK and instruction command of each base station apparatus to a transmission rate control section ( 240 ), which then selects, based on the ACK/NACK information, from among the instruction commands received from the base station apparatuses, the instruction command that should be employed on a priority basis during an actual transmission rate control and that is received from a base station apparatus having a highest priority.
