Abstract  Abstract

PROBLEM TO BE SOLVED: To provide improved ways for synchronization of terminals in a system in which a network infrastructure is not available.

SOLUTION: Peer to peer communication timing e.g. for an ad hoc network is referenced with respect to an external broadcast signal from a terrestrial or satellite based transmitter. Wireless terminals seeking to communicate via peer to peer communications receive the reference broadcast signal and set their internal timing structure with respect to the reference signal. This facilitates peer to peer timing coordination. A wireless terminal transmits a signal e.g. a user beacon signal identifying its presence during a time interval during which another wireless terminal is expected to be monitoring. Reference signal based coordinated timing and use of user beacon signals allow the wireless terminals to maintain situational awareness and coordinate peer to peer communications while keeping power consumption low.
