When a mobile station controls the transmission power of the uplink using
transmission power control information that is sent from a plurality of
base stations with which the mobile station is communicating, a
radio-state-monitoring unit 68.sub.1 to 68.sub.N monitors the radio
states between each base station and the mobile station, then based on
the radio state, a power-control-algorithm-instruction unit 69 instructs
a transmission power control unit 70 which of a plurality of
power-control algorithms should be executed to control the power, and a
transmission power control unit stores the plurality of power-control
algorithms for control the uplink transmission power using TPC
information and controls the uplink transmission power of the mobile
station based on the instructed power-control algorithm.
