- obtaining a reference signal from a signal source;
determining a reference time instant from the obtained reference signal;
deriving starting time instants of a sequence of paging intervals as a function of the reference time instant; and
monitoring during the sequence of paging intervals for a paging message directly sent by a peer,wherein monitoring during the sequence of paging intervals further comprises;
determining a first subset of times during a particular paging interval in the sequence of paging intervals as a function of an identifier of the first wireless terminal; and
monitoring the first subset of times during the particular paging interval for the paging message directly sent by the peer,wherein the method further comprises transmitting a disparate paging message to a disparate peer rather than monitoring for the paging message during the first subset of times when an urgency is above a threshold, the urgency being associated with paging the disparate peer when the first subset of times coincides with a second subset of times.

Abstract
Systems and methodologies are described that facilitate paging a peer in a peer-to-peer communication network. Paging messages may be communicated directly between a wireless terminal and its peer(s). Further, the wireless terminal may monitor for incoming paging messages during subinterval(s) of a paging interval as a function of an identifier of the wireless terminal. Moreover, the wireless terminal may transmit a paging message to a peer (e.g., detected and/or identified during peer discovery) during subinterval(s) of the paging interval as a function of an identifier of the peer.
