Abstract:
Angle of arrival (AOA) and differential AOA (DAOA) positioning for a user equipment (UE) is enhanced by using the UE's inertial sensors to track UE motion and change in angular UE orientation. UE location may be computed, by the UE or a location server, using triangulation for AOA measurements relative to a global reference frame or using multilateration for DAOA measurements. The computed UE location may remain accurate even when the UE is moving while obtaining measurements. The UE can also use AOA and DAOA measurements using 3D angles to increase accuracy when the UE and measured base stations are not in the same horizontal plane. 3D angles can also be used to identify whether the UE is close to a serving base station to improve accuracy further. Various non-AOA measurements may also be used to supplement AOA and DAOA measurements.

Claim (Index 20):
A user equipment (UE) comprising:\n a wireless communication interface; one or more inertial sensors; a memory; and one or more processing units communicatively coupled with the wireless communication interface, the one or more inertial sensors, and the memory, wherein the one or more processing units is configured to cause the UE to:\n obtain, with the wireless communication interface at a first time, a first Angle Of Arrival (AOA) measurement of Radio Frequency (RF) signals received by the UE from a first base station; \n obtain, using the one or more inertial sensors, first sensor location information indicative of movement of the UE between the first time and a second time; \n obtain, with the wireless communication interface at the second time, a second AOA measurement of RF signals received by the UE from a second base station; and \n provide location information to a location determining entity, the location information comprising information indicative of the first AOA measurement, the first sensor location information, and the second AOA measurement.
