Abstract:
1. A method of a Relay Station (RS) in a wireless communication system, the method comprising: relaying communications between a Base Station (BS) and a Mobile Station (MS); determining whether a dedicated resource is necessary for the communications with the MS, based on channel conditions between the RS and the MS; generating a dedicated access zone request message requesting the BS to allocate a dedicated access zone to the RS, the dedicated access zone request message including bandwidth information; transmitting the dedicated access zone request message to the BS; receiving a dedicated access zone allocation message from the BS; determining whether a dedicated resource, designated by the allocation message, is allocated to the RS; and scheduling the dedicated resource based on the dedicated resource zone allocation message received from the BS, wherein the dedicated access zone comprises resources which the RS only uses for a dedicated communication between the RS and the MS, and wherein the determining of whether the dedicated resource is necessary comprises determining whether a Carrier to Interference plus Noise Ratio (CINR) of a channel between the RS and MS exceeds a threshold.
