A wireless relay communication system of the present invention mainly includes BS, RS and subscriber terminal. A wireless relay communication method mainly includes: respectively setting downlink relay area and uplink relay area in downlink subframe and uplink subframe of frame structure of physical layer of the BS and respectively setting downlink relay area and uplink relay area in downlink subframe and uplink subframe of frame structure of physical layer of the RS for defining the combination of relay slot or relay subchannel and OFDMA symbol; wireless relay communicating between BS, RS and the subscriber terminals based on the set downlink and uplink frame of the physical layer. The realization of the present invention enable wireless communication system to support advanced relay communication mode, that is to say that MSS/SS can wireless relay access to BS via RS, thereby efficiently extending the valid covering range of BS and increasing the throughput of MSS/SS. |
