1. A method for use in supporting peer-to-peer trilateration (PPT), the method comprising:
- with a first peer device;
receiving a PPT request message from another device over a wireless communication link, wherein said PPT request message is associated with a peer-to-peer positioning operation;
transmitting at least a first PPT beacon signal to at least a second peer device during at least a first portion of a first assigned time slot, in response to said PPT request message; and
selectively transmitting at least a second PPT beacon signal to at least said second peer device during at least a second portion of said first assigned time slot or at least a portion of a second assigned time slot.
