Coding methods of communicating identifiers in peer discovery in a peer-to-peer network

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).

主权项

1. A method that facilitates incorporating reserved symbols within a peer discovery interval, comprising:
receiving a timing signal at a wireless terminal from a source outside a peer to peer network; synchronizing timing at the wireless terminal, the timing being within a peer to peer network, the peer to peer network comprising direct communication between wireless terminals; transmitting from the wireless terminal at least a portion of an identifier during a peer discovery interval as specified by the timing; and reserving at least one symbol within the peer discovery interval to enable identifying and recovering from timing offset.
