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： 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： Techniques for transmitting signals using time hopping or time and frequency hopping are described. In one design, a terminal selects different slots to use for transmission in multiple frames with time hopping. Each frame includes multiple slots, and each slot covers a particular time duration. The selected slots are at different time locations in the multiple frames. In another design, a terminal selects different resource units to use for transmission in multiple frames with time and frequency hopping. The selected resource units are at different time and frequency locations in the multiple frames. For both designs, the terminal sends a signal (e.g., a peer discovery signal) in the selected slots or resource units in the multiple frames. The terminal may detect for signals (e.g., peer discovery signals) from other terminals in slots not used for transmission by the terminal.

摘要： Methods and apparatus related to peer to peer communication networks are described. A peer to peer timing structure is implemented which includes recurring peer discovery intervals and traffic intervals. During a peer discovery interval, a wireless communications device, supporting peer to peer communications, monitors for and receives a broadcast signal from another peer wireless communications device, recovers an identifier from the received broadcast signal, and stores the received identifier in memory. The identifier is one of a device identifier and a user identifier. The wireless communications device maintains a list of discovered identifiers in its vicinity. In some embodiments, paging intervals are also included in the recurring peer to peer timing structure. In various embodiments, a wireless communications device receives or sends a page to a peer node prior to sending or receiving user data in a traffic interval. Various features are directed to peer paging protocol implementations.

摘要： Systems and methodologies are described that facilitate sharing bandwidth between a wide area network and a local area peer-to-peer network. The peer-to-peer network may use an air interface technology that is similar or distinct from an air interface technology used in the wide area network. Moreover, the wide area network and the local area peer-to-peer network may utilize distinct sets of parameters. For example, if the wide area network and the peer-to-peer network use OFDM-based air interface technologies, parameters such as tone spacing, symbol time, cyclic prefix, and the like of the two networks may vary. Further, peer-to-peer parameters may be a function of parameters for the wide area network.

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： A first wireless communications device includes a wide area network (WAN) interface and a peer to peer interface. The first device discovers the presence of a second wireless communications device via a peer discovery signal, received via its peer to peer interface. The second device has been transmitting, e.g., periodically, certain information, e.g., its location and/or shopping preferences, to a node within the WAN. The detected first signal triggers an application alert in the first device. The first device recovers past information about the second device through a second signal received via its WAN interface. The first device uses information communicated in the first signal, e.g., device identifier information, and information communicated in the second signal, e.g., past location and/or shopping information, to generate a targeted message for the second device. The first device communicates the targeted message via its peer to peer interface in a peer to peer traffic channel.

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.
