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 relating to scheduling of air link resources, e.g., traffic segments, in wireless communications 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. A first wireless terminal receives a transmission request and quality of service information from a second wireless terminal corresponding to a connection. The first wireless terminal decides not to receiver yield, determines a request response transmission power level as a function of the received quality of service information, and transmits, at the determined power level, a generated request response signal. By controllably adjusting the transmission power level of a request response, transmitter yielding decisions of lower priority links are impacted, since lower priority links measure and use received power level information corresponding to request responses of higher priority links in their transmitter yielding decisions.

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 wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal. FIG. 4

摘要： Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).
