Abstract
An apparatus and method for supporting Peer-to-Peer (P2P) communications in a broadband wireless communication system are provided. A frame used by the terminal in P2P communications includes a plurality of P2P contention channels overlapping with a region for cellular communications and at least one P2P dedicated channel allocated by a base station only for the P2P communications. The method includes establishing a P2P connection with a correspondent terminal through the at least one P2P dedicated channel, and exchanging P2P communication data with the correspondent terminal through at least one of the plurality of P2P contention channels.
Claims54
A method for allocating resources for Peer-to-Peer (P2P) communications in a base station of a wireless communication system, the method comprising:
- allocating resources for a plurality of P2P contention channels, in a frame, which are contention-based channels to be used between terminals for the P2P communications and at least one P2P dedicated channel for the P2P communications;
- and
- transmitting resource allocation information for the plurality of P2P contention channels and the at least one P2P dedicated channel to at least one terminal,
- wherein at least one of the plurality of contention channels is used for the P2P communication, when one of the at least one terminal occupies the at least one of the plurality of P2P contention channels based on a contention, in time and frequency domain, with at least one resource for cellular communications.
An apparatus for allocating resources for Peer-to-Peer (P2P) communications in a base station of a wireless communication system, the method comprising:
- a controller configured to allocate resources for a plurality of P2P contention channels, in a frame, which are contention-based channels to be used between terminals for the P2P communications and at least one P2P dedicated channel for the P2P communications;
- and
- a transmitter configured to transmit resource allocation information for the plurality of P2P contention channels and the at least one P2P dedicated channel to at least one terminal,
- wherein at least one of the plurality of P2P contention channels is used for the P2P communication, when one of the at least one terminal occupies the at least one of the plurality of P2P contention channels based on a contention, in time and frequency domain, with at least one resource for cellular communications.
A method for operating a first terminal to perform Peer-to-Peer (P2P) communications with a second terminal in a wireless communication system, the method comprising:
- performing a procedure to establish a P2P connection with the second terminal through at least one P2P dedicated channel allocated by a base station for P2P communications;
- and
- transmitting or receiving P2P communication data with the second terminal through at least one of P2P contention channels, in a frame, which are contention-based channels to be used between terminals for the P2P communications,
- wherein the at least one of P2P contention channels is used for the P2P communication, when the first terminal occupies the at least one of P2P contention channels based on a contention, in time and frequency domain, with at least one resource for cellular communications.
An apparatus for operating a first terminal to perform Peer-to-Peer (P2P) communications with a second terminal in a wireless communication system, the apparatus comprising:
- a controller for performing a procedure to establish a P2P connection with the second terminal through at least one P2P dedicated channel allocated by a base station for P2P communications, and transmitting or receiving P2P communication data with the second terminal through at least one of P2P contention channels, in a frame, which are contention-based channels to be used between terminals for the P2P communications,
- wherein the at least one of P2P contention channels is used for the P2P communication, when the first terminal occupies the at least one of P2P contention channels based on a contention, in time and frequency domain, with at least one resource for cellular communications.
