APPARATUS AND METHOD FOR SUPPORTING PEER TO PEER COMMUNICATION IN A BROADBAND WIRELESS COMMUNICATION SYSTEM
First Claim
1. An operation method of a Mobile Station (MS) in a wireless communication system supporting Peer to Peer (P2P) communication,wherein a P2P zone within a frame used for the P2P communication includes at least one channel, each channel comprises a broadcasting zone and a contention zone, and a P2P-mode transmit MS transmits a reference signal through a broadcasting zone of a channel to which it belongs,the method comprising:
- determining an interference sum for each channel within the P2P zone;
comparing the determined interference sums with each other;
selecting a channel comprising the least interference sum; and
transmitting information regarding the selected channel to a Base Station (BS).

Abstract
An apparatus and method for supporting Peer to Peer (P2P) communication in a broadband wireless communication system are provided. A P2P zone within a frame used for the P2P communication includes at least one channel, each channel includes a broadcasting zone and a contention zone, and a P2P-mode transmit Mobile Station (MS) transmits a reference signal through a broadcasting zone of a channel to which itself belongs. The method MS includes determining an interference sum for each channel within the P2P zone, comparing the determined interference sums with each other, selecting a channel having the least interference sum, and transmitting information regarding the selected channel to a Base Station (BS).
