摘要： Methods and apparatus related to peer, network or service discovery in a mobile wireless system, such as an ad hoc peer-to-peer network, are described. Transmission of discovery information, such as upper layer discovery information, is divided into a number of portions to be transmitted separately over time. Transmission of the individual portions is structured to enable flexibility in the frequency of the peer discovery transmissions as well as the monitoring of such transmissions. Various embodiments facilitate rapid discovery and secure discovery, such as selective discovery by trusted peers. The structuring enables proxying of some transmissions by a third party, such as an assist node. The assist node receives discovery information portions being communicated at a first rate and retransmits the received discovery information portions at a second rate which is higher than the first rate.

摘要： Methods and apparatus for controlling switching between resources and/or communicating resource change information in a wireless communications system are described. Various methods and apparatus are well suited for use in a decentralized wireless communications network, such as a decentralized peer to peer wireless network, where an individual communications device self allocates resources and makes resource switching decisions. A first communications device may decide that there is a need to switch from the first communications resource corresponding to a first identifier to a second communications resource corresponding to a second identifier, e.g., because of interference. The first communications device generates and transmits a broadcast change signal indicating a change from the first communications resource associated with the first identifier to a second communications resource associated with the second identifier. In some embodiments, the resource change signal is transmitted on at least one of the first and second communications resources.

摘要： Methods and apparatus implementing communications using different types of symbols, e.g. different characteristic OFDM symbols, at different times for different purposes are described. A first type of symbol is used for control signaling including conveying transmission request signals and/or transmission request response signals. A second type of symbol is used for conveying user data, e.g., traffic signals. The symbol period for a first type symbol is larger than the symbol period for a second type symbol. The tone spacing for a first type symbol is larger than the tone spacing for a second type symbol. The methods and apparatus are well suited for peer to peer communications systems in which a peer to peer communications device operates in a half-duplex mode of operation.

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： Methods and apparatus for detecting, controlling and/or mitigating interference are described. Various embodiments are well suited to wireless communications systems in which shared communications resources are used, e.g., in a peer to peer communications systems lacking centralized control. In some embodiments, a communications device receives signals on shared communications resource, evaluates its capability to decode a received signal, and conditionally transmits an interference signal, e.g., on the shared communications resource. The interference signal is intended to cause a device transmitting on the shared communications resource to switch to a different communications resource, e.g., in response to the interference signal, so that its transmitted signal can be successfully decoded. In at least one embodiment, the shared communications resource is a peer discovery air link resource associated with a peer discovery resource identifier.

摘要： Aspects relate to interference management in a multiple-input-multiple-output peer-to-peer network utilizing connection scheduling. When channel side information is available at both transmitter and receiver, both devices determine transmit/receiver beamforming vectors. Transmitter sends a first transmission request signal with first transmit beamforming vector and a second transmission request signal with second transmit beamforming vector in a transmission request block. Receiver estimates SINRs of the MIMO channels associated with the receive beamforming vectors and determines whether to return request response signals. Based on received request response signals, transmitter decides to transmit streams of data using the corresponding transmit beamforming vectors in the data burst. When channel side information is available only at receiver, transmitter sends one transmission request signal. Receiver estimates the SINRs of the MIMO channels associated with receive beamforming vectors using MMSE and/or successive interference cancellation (SIC), and returns request response signals in the request response block.

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 communicate traffic signals makes a receiver yielding decision. The receiver yielding decision, in some embodiments, includes comparing a link quality estimate corresponding to its own link, to a dynamically generated receiver yielding threshold. The dynamically generated receiver 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 its own link.

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 scheduling decisions of a peer to peer communications device for transmission into traffic intervals are described. A first peer to peer communications device maintains a set of information which allows it to base a scheduling decision for a current traffic interval upon prior performance in a prior traffic interval in which users of other connections were also operating. In some embodiments, the set of information includes a list of device or connection identifiers which the first peer to peer communications device has previously determined to have corresponded to a prior traffic interval in which the first peer to peer device had a low determined data rate. In some embodiments, the set of information includes: (i) a list of device or connection identifiers corresponding to prior traffic intervals and (ii) first peer to peer device data rate information associated with the prior traffic intervals
