Method of transmitting transmit power control command in wireless communication system

But in a wireless communication system TPC (transmit power control) commands transmission method comprising transmitting step and the downlink control information constituting the downlink control information including a plurality of TPC commands over the downlink control channel, wherein CRC (Cyclic Redundancy Check) of downlink control information are masked a TPC identifier. It made using the TPC command received on a downlink control channel by controlling the transmission power of the uplink channel other mitigate interference with the terminal, and can reduce battery consumption of the terminal.
