An apparatus and method for performing Uplink (UL) communication by a Relay Station (RS) in a wireless communication system are provided. The RS receives a Transmit/receive Transition Gap (TTG) and a Receive/transmit Transition Gap (RTG) of a Base Station (BS) during a network entry process of the RS, receives, from the BS, an idle time R_IdleTime between frames used in the RS, and determines a structure of a UL frame. In the alternative, the RS determines a time interval Tad or an idle time R_IdleTime according to a predetermined scheme, and transmits the Tad or the R_IdleTime to the BS. The proposed apparatus and method reduce an overhead of a frame structure when the RS transitions from a transmission mode to a reception mode or from a reception mode to a transmission mode, the frame structure being for frames of the BS and it adjacent RS, thereby reducing interference.
