Provided are a method and apparatus for setting a frame of a relay station in a wireless communication system. A base station sets an access zone frame and a relay zone frame adjacent the access zone frame. The access zone frame comprises a downlink (DL) access zone in which the base station or the relay station transmits a signal to a terminal, and an uplink (UL) access zone in which the terminal transmits a signal to the base station or to the relay station. The relay zone frame comprises a DL relay zone in which the base station transmits a signal to the terminal or to the relay station, and a UL relay zone in which the terminal or the relay station transmits a signal to the base station.
