摘要： Methods and apparatus related to peer to peer communication networks are described. An active connection list is maintained by a wireless communications device supporting peer to peer communications. In various embodiments, the active connection identifier list being maintained is in addition to a list of discovered peers in the local vicinity. Paging signaling, e.g., peer to peer paging signaling, is used to establish active connections. Air link peer to peer traffic resources include traffic control resources and traffic data resources. A wireless communications device seeking to transmit on a traffic data resource transmits a traffic request signal on a traffic control resource. An active connection identifier is, in some embodiments, associated with a particular subset of traffic control resources. Thus, a wireless communications device monitors the portion or portions of the traffic control resource corresponding to its active connections for traffic request signals, but need not monitor other portions.

摘要： To mitigate interference between multiple peer-to-peer devices, transmitter yielding and/or receiver yielding may be performed among devices operating in a peer-to-peer network. Generally, a transmitter device will yield communications on a time slot to a higher priority transmitter device if it will cause unacceptable interference to a higher priority receiver device. Likewise, a receiver device may yield use of the time slot if interference is unacceptably high. Both transmitter and receiver yielding may be improved by use of beamforming at a receiver device. By utilizing beamforming information to make the transmitter and/or receiver yielding decisions, better interference mitigation may be achieved.

摘要： A peer to peer communications system implements scheduling of traffic intervals in a distributed manner utilizing connection priority and interference information. A peer to peer timing structure includes a user scheduling interval, with ordered transmission request and response intervals, and an associated traffic interval. The priority associated with a request of an early interval is higher than the priority of a request of a later interval. A first device, connected to a second device, makes a decision as to whether or not to yield the traffic interval as a function of estimated interference that it will impose on higher priority connection receivers if it transmits during the traffic interval. The second device makes a decision as to whether or not to transmit a positive transmission request response signal as a function of a generated received signal quality value, based on received requests for its own and for higher priority connections.

摘要： Methods and apparatus for supporting multiple modes of communication operation, e.g., with different parameters and/or frequency bands being used in the different modes of operation are described. One or more adjustments are made based on a signal or signals received in a first frequency band from a second communications device, e.g., an access router with reliable timing. The communications device selects between and operates in either the first frequency band, e.g., a WAN frequency band, or in a second frequency band, e.g., a LAN frequency band. The WAN and LAN frequency bands may be non-overlapping. One or more parameters used in the second frequency band have a predetermined relationship to one or more parameters used for communications in the first frequency band making the adjustment based on the signal received in the first frequency band relevant and useful to support communications in the second frequency band.

摘要： Systems and methodologies are described that facilitate paging within a peer-to-peer communication network. A first wireless terminal monitors the paging channel of a wide area network. When a second wireless terminal intends to establish a peer-to-peer connection with the first wireless terminal, the second wireless terminal generates a paging message and transfers the message to the WAN, which routes the paging message to a base station. The base station uses its paging channel to send a paging message to the target first wireless terminal. The paging message indicates to the target first wireless terminal that the second wireless terminal intends to establish a peer-to-peer connection with the first wireless terminal. The paging message may further include parameters to be used to establish the peer-to-peer connection. Upon reception of the paging message, the second wireless terminal sends a signal directly to the first wireless terminal to start the direct peer-to-peer communication.

摘要： Methods and apparatus related to the communication of traffic in peer to peer communications are described. A peer to peer communications system includes traffic slots, and for a pair of devices having a connection a first transmission request resource and a second transmission request resource are associated with a traffic transmission interval of the traffic slot, the first request resource preceding the second request resource. The first request resource is used for the first device to communicate a request to transmit traffic to the second device. The second request resource is used to communicate a request from the second device to transmit traffic to the first device. One protocol calls for a second resource request to override a first resource request. In another protocol the second resource is used to communicate additional information corresponding to a first resource request, when a request is communicated in the first resource.
