1. A method for controlling uplink transmit power by an Access Terminal (AT) in a mobile communication system using a Time Division Duplexing (TDD) scheme, the method comprising the steps of:

  • determining initial uplink transmit power;

    transmitting uplink signals to an Access Point (AP) using the determined initial uplink transmit power;

    receiving downlink signals from the AP;

    measuring receive power of the received downlink signals;

    detecting a power compensation value from the received downlink signals in order to compensate for the uplink transmit power, the power compensation value being determined according to whether an error has occurred in the uplink signals; and

    adjusting the uplink transmit power according to the measured receive power and the detected power compensation value.
