摘要： Methods and apparatus supporting enhanced discovery operations in peer to peer networks are described. Peer discovery, based on direct peer to peer discovery between two mobile nodes can be somewhat limited, e.g., due to power limitations, processing power, and/or channel conditions. An access point, e.g., base station, monitors for and receives peer discovery signals conveying a set of identifiers from a wireless communications device. The access point retransmits at least one identifier in the set in a wireless peer to peer communications channel. Thus the access point effectively extends the peer discovery range for wireless communications devices utilizing the peer to peer network. Wireless communications devices can monitor for and recover the rebroadcast peer discovery signals from access points. Thus, via access point signaling a wireless communications device can be made situationally aware of other devices of interest which would be otherwise outside its discovery detection range.

摘要： Methods and apparatus for communicating the location of a mobile wireless communications device are described. Codewords, e.g., values or sets of bits, are selected from a codebook mapping different codewords to corresponding pieces of location information. In a first approach location information is communicated by using codewords from different codebooks with the product, e.g., intersection of location information provided by the codewords, providing relatively detailed location information using relatively few bits. In a second approach user specific codebooks are defined for individual users. The codewords in the codebook corresponding to a particular user map to locations the individual specific user is likely to frequent. In another approach codewords are transmitted at different power levels and/or using different coding rates. Received codewords corresponding to a device may be used in combination to determine the location or refine the understanding of the device location.

摘要： One or more bits are used in peer discovery signals to signal a device's ability and/or willingness to participate in a cooperative manner with regard to one or more mobile device location determination related operations. In some embodiments, the one or more bits are located at predetermined locations within a header portion of a peer discovery signal. Different bits, in some embodiments, are associated with different specific cooperative location determination related operations. The peer discovery signal is transmitted, e.g., broadcast, periodically or on some predetermined basis by a mobile wireless communications device. In this manner, a device listening to the peer discovery signals can determine other devices' willingness to perform particular location discovery related operations with very little signaling overhead.

摘要： Methods and apparatus for resolving an ambiguity with regard to a mobile device's location are described. In various embodiments, when a level of ambiguity with regard to the location of a mobile device is detected, and the level of ambiguity is above a threshold, an ambiguity resolution request signal is generated and transmitted. In this manner, a wireless terminal needing help in determining its location reliably may request such help but at other times may determine its own location without assistance. In some embodiments the ambiguity resolution request signal includes information, e.g., location probabilities, on one or more locations which are under consideration as possible locations of the mobile device. A device responding to the ambiguity resolution request provides information allowing the mobile device confronted with a location ambiguity to eliminate at least on location under consideration or to generate a new probability for one or more locations under consideration.

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： 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： Methods and apparatus related to peer to peer communication networks are described. A wireless communications device supports peer to peer communications with multiple peers. The wireless communications device determines its transmit timing synchronization based on a reference signal received from a node such as a base station, a satellite, or a beacon transmitter which does not transmit user data. The wireless communications device determines a plurality of different receive timing adjustments corresponding to different peer communications devices based on signals received from those peer communications devices. The wireless communications device stores the plurality of determined receive timing adjustment information corresponding to the different peer communications devices. The wireless communications device retrieves and applies stored receive timing adjustment information which matches the particular device which transmitted the signal attempting to be recovered.
