Abstract
An apparatus and method for supporting heterogeneous systems in a multi-hop relay wireless communication system are provided. In a method of transmitting and receiving a DownLink (DL) frame of a Base Station (BS) in a multi-hop relay wireless communication system employing heterogeneous systems, the DL frame of the BS includes a legacy zone for communication with a legacy Mobile Station (MS), an access zone of a new zone for communication with a new MS, and a relay zone of the new zone for communication with a new Relay Station (RS). The method includes transmitting DL data to the legacy MS in the legacy zone, transmitting the DL data to the new MS in the access zone of the new zone, and transmitting the DL data to the new RS in the relay zone of the new zone.
