Abstract: Disclosed is an apparatus and a method for controlling automatic gain in a wireless communication system using a Time Division Duplex (TDD) scheme. The apparatus comprises a power detecting unit for detecting a power of a TDD frame signal on a receive path; an Automatic Gain Control (AGC) synchronizing signal generating unit for generating an AGC synchronizing signal enabled or disabled either during a Down Link (DL) frame or during an Up Link (UL) frame of a TDD frame; an automatic gain calculating unit for calculating a gain control value based on the power detected by the power detecting unit either during the DL frame or during the UL frame of the TDD frame in response to the AGC synchronizing signal; and an AGC unit for performing gain control for the TDD frame signal on the receive path on the basis of the calculated gain control value. Hence, as AGC is performed during only an actual receive frame, the optimized demodulation performance can be maintained.
