摘要

A mobile station apparatus enabling increases in communication system capacity when uplink high-speed packet communication is performed and the like. The mobile station having a plurality of antennas, antenna 1 and antenna 2, compares the reception power of a signal r 21 received in antenna 1 with the reception power of a signal r 22 received in antenna 2 among signals transmitted from base station 2 of an adjacent cell, selects antenna 1 as a transmission antenna when "the reception power of r 21
