ABSTRACT:
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 unit506compares 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 controller507.When the base station in question is a non-transmitting base station, transmission power controller507transmits 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.
