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.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in a wireless communications system are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. An individual wireless terminal corresponding to a peer to peer connection which desires to transmit traffic signals make transmitter yielding decisions on a traffic slot by traffic slot basis. The transmitter yielding decision, in some embodiments, includes comparing a link quality estimate corresponding to a higher priority link intending to use the same traffic segment concurrently, to a dynamically generated transmitter yielding threshold. The dynamically generated transmitter yielding threshold is determined based on at least one of: quality of service information corresponding to its own link and historical link quality information corresponding to the higher priority link.

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 peer to peer timing structure is implemented which includes a pattern of different types of time intervals including at least a peer discovery time interval and a traffic interval. A wireless communications device, supporting peer to peer operations stores the peer to peer timing structure information, accesses the stored information, and used the accessed information to determine an operation to be performed during a current time period. The operation is, e.g., a peer discovery operation, a peer to peer timing synchronization operation, a peer paging operation, or a peer to peer traffic signaling operation. Various exemplary relationships between the different types of intervals, including relative frequencies, relative durations, and spacing information, are described. Advantageous construction of the recurring peer to peer timing structure facilitates efficient utilization of air link resources and/or higher traffic data throughput capabilities.

摘要： Methods and apparatus related to scheduling traffic slots in a wireless communications system, e.g., an ad hoc peer to peer communications network are described. An implemented timing structure includes multiple traffic transmission slots and multiple request blocks with different priorities corresponding to a traffic transmission slot. A wireless terminal determines its own block priority level. If a wireless terminal's determined block priority level is the highest block priority level the wireless terminal is allowed to transmit a traffic transmission request in the highest traffic transmission request block; otherwise, the wireless terminal is restricted from transmitting a traffic transmission request in the highest priority request block. A wireless terminal monitors for request and/or request response activity corresponding to other connections high priority block signaling, and uses the collected information to determine its own block priority.

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.
