IMPROVEMENTS ON OTDOA AND AGNSS POSITIONING AND TIMING INFORMATION OBTAINING AND UPDATING

摘要

The present invention generally relates to signal detection and measurements and cell detection in wireless communications networks and in particular to wireless communication network architectures that utilize signal measurements from multiple cells for positioning, location and location-based services. In a method for OTDA positioning in a wireless communication network, the wireless communication network including a UE and at least two base stations, the method comprising: sending to the UE OTDOA assistance data including a search window; at the UE, searching signals for OTDOA measurement from the base stations by using the search window, wherein the search window is determined by measurement(s) or positioning method(s) not relating to the OTDOA measurement.
