The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for controlling uplink transmission power in a multi-carrier wireless communication system. The method in which a terminal controls uplink transmission power in a multi-carrier wireless communication system according to one embodiment of the present invention comprises the following steps: receiving, from a base station, downlink control information containing an uplink transmission power control command, and one or more pieces of uplink carrier indicator information for indicating an uplink carrier to which the uplink transmission power control command is to be applied; determining an uplink carrier, to which the uplink transmission power control command is to be applied, on the basis of said one or more pieces of uplink carrier indicator information; determining a transmission power for the determined uplink carrier on the basis of the downlink control information; and transmitting, to the base station, an uplink signal on the determined uplink carrier on the basis of the determined transmission power. |
