Abstract:
Methods and systems for determining a location of a UE includes receiving UE position information from a UE being serviced by a plurality of base stations. The UE position information may include a signal reception time and a signal transmission time or a timing advance for at least two of the plurality of base stations. The signal transmission time being a measured time for a signal being transmitted by the UE to be received by a base station, the signal reception time being a measured time for a signal being transmitted by the base station to be received by the UE, and the timing advance being a difference between the signal transmission time and the signal reception time for the base station. The method may include determining a location of the UE based on the received UE position information.
