Abstract: A power control method of a TDD(Time Division Duplex) communication system and a device thereof are provided to offer an excellent-performance power control method without requiring a separate feedback value, with regards to noncontinuous uplink channels that many users temporally separate and occupy one channel, thereby supporting noncontinuous uplink users. Uplink power determiners(1115,1116) determine uplink power values by using the quantity of external cell interference received from a base station, power control calculation factors of the current frame obtained by using power increase/decrease variation estimated through downlink, and power control calculation factors of a previous frame. An uplink power controller(1117) transmits the uplink power values to a transmitter to control uplink power.
