Methods and apparatus for controlling peer to peer communications
A wireless communications system supports both cellular communications and direct peer to peer communications. The cellular communications use FDD downlink and uplink bands for control and traffic signaling. An access point employs control over direct peer to peer communications. Peer to peer mode control signals from the access point are transmitted to wireless terminals using the FDD cellular downlink band. Peer to peer mode control signals from wireless terminals are transmitted to an access point using the FDD cellular uplink band. Peer to peer traffic signals between wireless terminals are communicated using a TDD band. In one embodiment, the access point communicates priority information to peer to peer network wireless terminals, and the wireless terminals make peer to peer traffic transmission decisions in a decentralized manner using the received priority information. In another embodiment, the access point directly schedules peer to peer traffic in the peer to peer network.
