Uplink transmission power control method

摘要

Disclosed is an uplink transmission power control method, by which a transmission power of an uplink signal is efficiently controlled while a terminal communicates with a plurality of base stations. The present invention includes the steps of computing command values for a plurality of base stations in a terminal in soft handover with a plurality of the base stations transmitting power control commands to the terminal and lowering uplink transmission power if the command values computed for a plurality of the base stations includes at least one power-down command. And, the present invention includes the steps of receiving a power control command transmitted from at least one base station, computing at least one command value according to the received power control command, and lowering uplink transmission power if the command value includes a transmission power-down command value.
