Abstract:
Techniques described herein are directed to position determination of a user equipment (UE) in an asynchronous wireless network, such as a 4G or 5G network. In one embodiment, a base station measures real time differences (RTDs) to neighboring base stations and a Round Trip signal propagation Time (RTT) to the UE and receives Reference Signal Time Difference (RSTD) measurements from the UE, whereby a location of the UE is determined using the RTD measurements, RTT measurement and RSTD measurements. In other embodiments, the UE may obtain the RTT and RSTD measurements and may receive RTD measurements from a base station, whereby a location of the UE is determined by the UE or by a location server.

Claim (Index 1):
A method of locating a User Equipment (UE) at a first base station, the method comprising:\n measuring a first time of arrival (TOA) of a first reference signal received from a second base station; determining a first Real Time Difference (RTD) between a first transmission from the first base station and a second transmission from the second base station, based at least in part on the first TOA; measuring a second TOA of an uplink signal received from the UE; determining a first Round Trip signal propagation Time (RTT) between the first base station and the UE based at least in part on the second TOA; receiving a first Reference Signal Time Difference (RSTD) for the first base station and the second base station from the UE; and sending location information for the UE to a location-capable device, wherein the location information is based at least in part on the first RTD, the first RTT, and the first RSTD.
