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 broadcast from another device over a wireless communication link to at least said first peer device and at least a second peer device as part of a peer-to-peer positioning operation in which said first peer device participates by transmitting one or more PPT beacon signals to at least said second peer device, and wherein said PPT request message is indicative to at least said second peer device to participate in said peer-to-peer positioning operation by preparing to receive said at least one PPT beacon signal from said first peer device;
in response to said PPT request message, transmitting at least a first PPT beacon signal to at least said second peer device during at least a first portion of a first assigned time slot; and
in response to a determination that said peer-to-peer positioning operation has not ended, 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, and wherein said first peer device comprises a target mobile station having a currently unknown location and said second peer device comprises a nomadic mobile station.

10. An apparatus for use in a first peer device enabled to support peer-to-peer trilateration (PPT), the apparatus comprising:
-
means for receiving a PPT request message broadcast from another device over a wireless communication link to at least said first peer device and at least a second peer device as part of a peer-to-peer positioning operation in which said first peer device participates by transmitting one or more PPT beacon signals to at least said second peer device, and wherein said PPT request message is indicative to at least said second peer device to participate in said peer-to-peer positioning operation by preparing to receive said at least one PPT beacon signal from said first peer device; means for initiating transmission of at least a first PPT beacon signal to at least said second peer device during at least a first portion of a first assigned time slot, in response to said PPT request message; and means for initiating transmission of 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, in response to a determination that said peer-to-peer positioning operation has not ended, and wherein said first peer device comprises a target mobile station having a currently unknown location and said second peer device comprises a nomadic mobile station. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A first peer device comprising:
-
a communication interface to receive a peer-to-peer trilateration (PPT) request message broadcast from another device over a wireless communication link to at least said first peer device and at least a second peer device as part of a peer-to-peer positioning operation in which said first peer device participates by transmitting one or more PPT beacon signals to at least said second peer device, and wherein said PPT request message is indicative to at least said second peer device to participate in said peer-to-peer positioning operation by preparing to receive said at least one PPT beacon signal from said first peer device; and a processing unit coupled to said communication interface to; initiate transmission of at least a first PPT beacon signal to at least said second peer device during at least a first portion of a first assigned time slot, in response to said PPT request message, and in response to a determination that said peer-to-peer positioning operation has not ended, initiate transmission of at least a second PPT beacon signal to 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, and wherein said first peer device comprises a target mobile station having a currently unknown location and said second peer device comprises a nomadic mobile station. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. An article comprising:
-
a non-transitory computer readable medium having computer implementable instructions stored thereon which are executable by one or more processing units in a first peer device to; access information received via a peer-to-peer trilateration (PPT) request message broadcast from another device over a wireless communication link to at least said first peer device and at least a second peer device as part of a peer-to-peer positioning operation in which said first peer device participates by transmitting one or more PPT beacon signals to at least said second peer device, and wherein said PPT request message is indicative to at least said second peer device to participate in said peer-to-peer positioning operation by preparing to receive said at least one PPT beacon signal from said first peer device; and based, at least in part thereon; initiate transmission of at least a first PPT beacon signal to at least said second peer device during at least a first portion of a first assigned time slot, and in response to a determination that said peer-to-peer positioning operation has not ended, initiate transmission of 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, and wherein said first peer device comprises a target mobile station having a currently unknown location and said second peer device comprises a nomadic mobile station. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
