    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling distributed frequency synchronization based on a fastest node clock rate. In one example, a first UE is equipped to determine that a fastest clock rate is faster than an internal clock rate of the first UE by more than a first positive offset, and adjust the internal clock rate based on the determined fastest clock rate. In an aspect, the fastest clock rate is associated with a second UE of one or more other UEs from which synchronization signals may be received. In another example, a UE is equipped to obtain GPS based timing information, adjust an internal clock rate based on the GPS based timing information, and transmit a synchronization signal at an artificially earlier time in comparison to a scheduled time of transmission associated with the adjusted internal clock rate.

    Abstract: 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).

    Abstract: Methods and apparatus for improved utilization of air link resources are discussed in wireless communications systems employing multi-sector base stations and wireless terminals with multiple antennas. Timing synchronization is maintained across the base station sectors, and the same set of tones are used in adjacent sectors. In a sector boundary region, which is typically a high interference region, a wireless terminal is set to a sector pair state and operated in a MIMO mode of operation, communicating with two adjacent base station antenna faces of the same base station concurrently, the two different adjacent base station antenna faces corresponding to different adjacent sectors. Thus, typically high interference sector boundary regions, are converted into high capacity regions by having the sectors coordinated and utilizing MIMO techniques.

    Abstract: Methods and apparatus for supporting peer to peer and infrastructure, e.g., cellular, communication in a multimode device which can operate in a cellular system are described. Methods and apparatus for supporting peer to peer devices are also described. Peer to peer communication occurs within a switching time period during which infrastructure signaling does not occur and devices switch between an uplink and a downlink mode of infrastructure operation. The time period set for the switching time period is intentionally set larger, e.g., 10, 50, 100 or even more times larger than that required based on maximum cell size. Thus, a peer to peer communications period can be introduced into a TDD system and use the same frequency band as the TDD system in a manner that can remain compliant with a cellular communications protocol which allows for a switching time period, e.g., set in the system by a parameter.
