Patent ID: 8270337

Claim:
A method of allocating a Peer-to-Peer (P2P) resource in a relay-based wireless communication system, the method comprising: receiving relay link resource information; determining, based on the relay link resource information, whether a current link is a multi-hop link; if the current link is a multi hop link, interference generated by the serving station is less than a threshold, a first interference of a relay link is less than a second interference of an access link, and the serving station comprises a Base Station (BS), reallocating a Relay Station (RS)-BS link resource; if the current link is a multi-hop hop link, interference generated by the serving station is less than a threshold, a first interference of a relay link is less than a second interference of an access link, and the serving station comprises an RS, reallocating a BS-RS link resource; determining a maximum transmittable power level for P2P communication; and performing P2P communication using the allocated resource.
