Abstract: White space signals are differentiated from licensed ATSC signals through modification of a waveform of the white space signal. White space signals may be modified by shifting the ATSC-compatible waveform so that the pilot frequency of the white space signal is at a location outside of the frequency range associated with the pilot frequency in a licensed ATSC signal or embedding a watermark signal into said ATSC-like white space signals. White space device transmitters generate the signals with these modifications and white space receivers are equipped to detect whether a pilot exists in the standard licensed pilot frequencies. Based on these differences, white space devices can better operate without interfering with licensed ATSC transmission. Additionally, the modification techniques may be used to embed data in the white space signal that may be used to communicate connection data or networking data to other white space devices.

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.
