Abstract

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for a terminal controlling uplink power in the wireless communication system, comprising the steps of: configuring an uplink subframe (UL SF) of a first set and a UL SF of a second set; receiving a downlink control information (DCI) format including a bitmap for indicating transmit power control (TPC) for a plurality of terminals; and controlling transmit power of an uplink channel by using TPC information on the terminals from the bitmap, wherein the TPC information is used for controlling transmit power of an uplink channel transmitted from the UL SF of the first set when the DCI format comprises a first identifier, and the TPC information is used for controlling transmit power of an uplink channel transmitted from the UL SF of the second set when the DCI format comprises a second identifier.
