Wireless device discovery in a wireless peer-to-peer network

摘要

Systems and methodologies are described that facilitate detecting and/or identifying peers in a local area peer-to-peer network. Times (e.g., peer discovery intervals) for performance of mutual detection and identification between peers may be synchronized (e.g., based upon a signal broadcast to the peers). Further, within each partitioned peer discovery interval, a wireless terminal may select a portion of time to transmit (e.g., broadcast) short messages that may be employed by peers to detect and/identify the wireless terminal. Moreover, the remainder of the time within the partitioned peer discovery interval may be employed to listen to short messages received from peers.

主权项

1. A method of operating a first wireless terminal in a peer-to-peer network, comprising:
receiving a first signal from a signal source wherein the signal source is at least one of a base station, an access node, or a GPS satellite; determining time positions of a first sequence of peer discovery intervals based upon the received first signal; and wherein an amount of time that separates two successive peer discovery intervals in the first sequence of peer discovery intervals is at least 100 times larger than a duration of time of either of the two successive peer discovery intervals.
