When performing base station selection type transmission power control, transmission of the dedicated physical control channel signal by non-transmitting base stations is halted while minimizing the impact on uplink transmission power control. This decreases downlink interference and increases downlink channel capacity. At a base station, reception quality measuring unit 506 compares the measured uplink reception quality with a target quality, forms a TPC signal on the basis of the results of this comparison, and communicates the contents of this TPC signal to transmission power controller 507. When the base station in question is a non-transmitting base station, transmission power controller 507 transmits the dedicated physical control channel signal only if the contents of the communicated TPC signal instruct a decrease, and otherwise halts transmission of the dedicated physical control channel signal.
