摘要： Techniques for enabling relay assisted peer discovery in a wireless communication network are disclosed. A relay may receive, from at least one user equipment (UE), at least one hashed expression to transmit. Further, a relay may compute a time dependent hash of the at least one hashed expression to transmit. The relay may broadcast, and the second UEs may receive, the time dependent hash of the at least one hashed expression. The UE may be, for example, an eNodeB. The hashed expression may be a time varied hashed expression.

摘要： Base station assisted peer to peer discovery methods are described. A wireless terminal communicates peer discovery expression information to a base station and information identifying a peer discovery resource that it intends to use but which may also be used by other devices. The base station associates the peer discovery expression and peer discovery resource with an index value to be communicated on the peer discovery resource. The base station transmits the peer discovery expression and information associating the peer discovery expression with the peer discovery resource and the index value. The wireless terminal transmits the index value on the peer discovery resource. A wireless terminal receiving the index value determines the peer discovery expression being communicated using information from the base station. Use of different indexes allows multiple devices to use the same discovery resource.

摘要： Aspects describe different multiple antenna techniques that can be utilized in a peer-to-peer network based on a network congestion level. A MIMO scheme where a transmitter sends to a receiver multiple spatial streams at substantially the same time in the same traffic segment can be utilized when network congestion level is low. A receiver beam forming scheme where transmitter sends a single stream in a traffic segment and receiver uses multiple receive antennas to maximize signal to noise ratio can be utilized when network congestion level is high. The connection pair (transmitter and receiver) occupy more control resources in the MIMO scheme than the receiver beam forming scheme. The decision related to which technique to utilize can be made at about the same time as a communication is initiated. Further, if network conditions change during a communication, the antenna technique that is utilized can be switched to a different technique during the communication exchange.

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.

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.
