Abstract: Techniques are provided for frequency and/or timing synchronization of a small base station with a network. In one example, small base station may be configured to detect a macro signal of a macro base station, and set a frequency reference based at least in part on the macro signal, in response to the macro signal being available in a different band than that for the small base station. The small base station may be configured to set the frequency reference based at least in part on a Global Positioning System (GPS) signal, in response to detecting that the different band macro signal is not available.

Abstract: Methods and apparatus are provided for use in peer-to-peer positioning operations in wireless networks. A method includes receiving a peer-to-peer trilateration (PPT) request message from another device over a wireless communication link, transmitting at least a first PPT beacon signal during at least a first portion of a first assigned time slot, in response to the PPT request message, and selectively transmitting at least a second PPT beacon signal during at least a second portion of the first assigned time slot or at least a portion of a second assigned time slot. A peer device may measure a time of arrival (TOA) for the beacon signal. When three or more TOAs are obtained from three or more peer devices, it may be possible to determine the location of the target mobile station. In accordance with further aspects, a PPT scheme may be enabled to discover, alert, and/or otherwise determine which peer devices may be geographically nearby a target mobile station and possibly available to support certain PPT operations.
