摘要： Methods and apparatus for determining whether two or more communications devices, e.g., wireless terminals, in a communications system should communicate using direct peer to peer communications or via one or more infrastructure elements, e.g., base stations, are described. The determination whether a given pair of communications devices should communicate using direct peer to peer communications, rather than via the infrastructure element(s), is determined by a control device. The control device instructs various wireless terminals to make various signal measurements and/or transmit signals to be measured. Based on the signal measurements the control device estimates interference caused by the direct peer to peer link to the existing communications devices, the direct peer to peer link channel quality and/or interference caused to such a direct peer to peer link by existing communications devices which are communicating using peer to peer signaling and makes a mode decision based on such information.

摘要： 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.

摘要： Methods and apparatus related to supporting rapid synchronization between groups of wireless communications devices are described. Described methods and apparatus are well suited for use in peer to peer wireless communications systems in which a plurality of ad hoc peer to peer networks may be formed, each ad hoc network operating with its own notion of time. As two groups of devices, having different notions of time, come within proximity of one another, a wireless communications device of a first group detects the presence of a member of a second group. The wireless device determines that network timing re-synchronization is to be performed by one of the first and second groups and transmits a re-synchronization alert signal on a dedicated resource. Subsequently, the wireless device transmits a timing synchronization signal in accordance with new timing. Intended devices, which detect the alert signal and timing synchronization signal, adjust their internal timing.

摘要： A wireless terminal detects timing signals from different local timing signal sources. The wireless terminal selects from the plurality of detected timing signal sources two timing signal sources in accordance with a predetermined timing signal source priority ordering. In some embodiments, the wireless terminal intentionally selects two timing signal sources which are not synchronized with respect to one another. The wireless terminal determines a first set of peer communications time intervals corresponding to a first selected timing signal source and a second set of peer communications time intervals corresponding to a second selected timing signal source. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the first set of peer communications time intervals. The wireless terminal transmits a peer to peer signal, e.g., a peer discovery signal, during at least one of the second set of peer communications time intervals.
