摘要： In an ad hoc peer-to-peer communications network, timing synchronization is facilitated between two or more nodes. A node can establish an original symbol timing and receive a first timing synchronization symbol from a peer node. A timing adjustment can be calculated based in part on the first timing synchronization symbol. An adjusted symbol timing can be established by adjusting the first symbol timing by the calculated timing adjustment amount. The adjusted symbol timing can be conveyed to one or more peer nodes, in order to facilitate timing synchronization among the nodes.

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 the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. A multi-mode wireless communications device supporting both WAN communications and peer to peer communications includes: a transmitter chain for generating signals having a first RF frequency, a first receiver chain for processing received signals having a second RF frequency, and a second receiver chain for processing signals having the first RF frequency. This design is particularly advantageous in a communications system where a WAN frequency division duplex uplink band is shared with time division duplex (TDD) peer to peer communications signaling. The wireless terminal sets the transmitter chain and the second receiver chain to the FDD uplink band and sets the first receiver chain to the FDD downlink band. This design accommodates rapid mode switching between the two modes of operation and reuses hardware where possible.

摘要： Methods and apparatus related to the sharing of wide area network (WAN) uplink bandwidth with peer to peer communication signaling usage are described. Typically, a base station uses its WAN uplink band to receive uplink signals from wireless terminals using the base station as a point of network attachment. In accordance with a feature, a base station injects a signal, e.g., a beacon signal, into its WAN uplink bandwidth, e.g., its WAN frequency division duplex (FDD) uplink band. A peer to peer wireless terminal scans the uplink bandwidth, detects the base station signal, evaluates the received base station signal, and controls peer to peer transmission as a function of the evaluation. Control of peer to peer transmission includes adjusting peer to peer transmission power as a function of the evaluated base station signal. The communications band used for peer to peer communications is, in some embodiments, the same uplink band.

摘要： Systems and methodologies are described that facilitate choosing parameters to utilize in a local area peer-to-peer network. The parameters may relate to tone spacing, cyclic prefix, symbol time, and the like. Further, the parameters may be a function of a state (e.g., peer discovery state, control related traffic state, data related traffic state,…) associated with the local area peer-to-peer network. Moreover, the local area peer-to-peer network may share spectrum with a wide area network; as such, parameters for the peer-to-peer network may be selected based on the type of wide area network (e.g., air interface technology) and/or wide area network related parameters.

摘要： Systems and methodologies are described that facilitate encoding and/or decoding signals utilized to identify a wireless terminal during peer discovery interval(s). Substantially any type of function that constrains encoding and/or decoding within a peer-to-peer network may be utilized. For example, a reversible function may be employed that enables a receiving peer to discern an identifier of a transmitting peer over a series of peer discovery intervals. Pursuant to another example, an irreversible function may be utilized whereby a receiving peer may be unable to decipher the identifier of the transmitting peer from a received signal; however, expected signal formats of buddy peers may be compared to the received signal to determine a presence of one of the buddy peers in a vicinity.

摘要： A wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. The wireless terminal monitors for and attempts to recover broadcast loading factor information corresponding to attachment points. The wireless terminal generates and transmits an interference report to a current attachment point, the report based on the results of a measured received reference signal from the current attachment point, a measured received reference signal from each of one or more different attachment points, and uplink loading factor information. In the absence of a successfully recovered broadcast uplink loading factor corresponding to an attachment point, the wireless terminal uses a default value for that loading factor. Generated interference reports are based on beacon signal measurements and uplink loading factors, pilot signal measurements and uplink loading factors, or a mixture of beacon and pilot signal measurements and uplink loading factors.

摘要： Methods and apparatus well suited for supporting communications over different ranges in, for example, a peer to peer wireless communications system, are described. In the peer to peer network at least some of the types of signals, e.g., peer discovery signals and/or paging signals, are transmitted with no closed loop power control. An exemplary peer to peer timing structure includes air link resources allocated for a particular type of signaling in which the resources are segmented into multiple blocks which do not overlap in time, different ones of the multiple blocks being associated with different ranges. The characteristics of the basic transmission units of the multiple blocks based on range are different, e.g., tone size and symbol width are different. A wireless communications device implements the peer to peer timing structure and uses resources from different range based blocks at different times. Data traffic transmission units may be the same regardless of the range.

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： 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.
