摘要： Methods and apparatus well suited to decentralized traffic scheduling in wireless peer to peer network are described. An individual wireless terminal corresponding to a peer to peer connection makes a transmitter yielding or receiver yielding decision for a traffic slot. Quality of service information is disseminated as part of the scheduling control signaling. A scheduling control signal, e.g., a traffic transmission request signal or a traffic transmission request response signal, includes a pilot portion and a quality of service information portion. The pilot facilitates the recovery of the quality of service information by a plurality of different devices which may have different channel conditions with respect to the transmitter of the scheduling control signal. The different devices may benefit from utilizing the recovered quality of service information in making a yielding decision regarding traffic signaling in a traffic segment.

摘要： Systems and methodologies are described that facilitate transmitting beacon symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified with carriers. In this regard, a coding scheme can be applied to a beacon message; the coding scheme can produce a plurality of beacon symbols to transmit on given subcarriers. A receiving device of the beacon symbols can decode a beacon message by receiving less than the total number of symbols in a beacon message and determining the remaining symbol subcarriers based on the linear constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy linear constraints for the symbols, and resolving time and frequency shift by detecting an offset that would result in satisfaction of the linear constraint.

摘要： Methods and apparatus related to partitioning traffic segments are described. An access router, having concurrent connections with two access terminals, each desiring to transmit traffic signals to the access router in the same traffic segment, partitions a traffic segment. The partition is such that a first portion of the traffic segment is allocated to a first access terminal and a second portion of the traffic segment is allocated to the second access terminal. Control information, e.g., conveying partition information, is communicated to access terminals prior to the traffic segment. In some embodiments, the partition information is communicated as part of a transmission request response signal, e.g., via phase of the request response signal. An access terminal which has been allocated a traffic segment partition portion identifies is allocation from the transmitted control information, and subsequently transmits traffic signals to the access router in its allocated portion of the traffic segment.

摘要： Various methods and apparatus are directed to achieving timing synchronization and propagating timing information pertaining to an external, e.g., non Wi-Fi, timing signal source. In some embodiments, a mobile communications device receives and processes a timing signal, e.g., a first Wi-Fi beacon, which is propagating timing information about an external timing signal from a device which directly received the external timing signal. Thus, a mobile wireless communications device achieves timing synchronization with respect to an external timing signal which it is unable to receive directly. In various embodiments, the mobile communications device may, and sometimes does, further propagate the timing information about the external timing signal, e.g., via a second Wi-Fi beacon signal which it generates and transmits. Synchronization with respect to an external signal source facilitates longer sleep states and decreased power consumption.
