    Abstract: In an embodiment, a given entity obtains a location of at least one terrestrial transmit station of a Synchronized Wireless Transmission Network (SWTN), transmit station calibration information associated with the at least one terrestrial transmit station and a location of a user equipment (UE) that is in wireless communication range with the at least one terrestrial transmit station. The given entity estimates the time calibration value for the UE based on the obtained transmit station location, the determined transmit station calibration information and the determined location of the UE. In another embodiment, a server obtains time calibration values that are estimated for each UE in the population of UEs. The server aggregates the estimated time calibration values based on device model and/or device operation mode, and calculates a representative time calibration value for UEs sharing the device model and/or device operation mode.

    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.

    Abstract: A spatially diverse antenna array may be used to reduce or eliminate multipath errors in ranging measurements for a mobile device. The spatial diversity in the antenna structure enables different locations of the antenna to experience different signal characteristics from which multipath signals may be identified. The measured relative reception time for each antenna in the array may be determined. The expected relative reception time for each antenna in the antenna array is determined based on an estimated location and orientation of the antenna array. The expected and measured relative reception times are fit to align the expected and measured relative reception times for one antenna such that for all other antennas the measured relative reception time is aligned or greater than the expected relative reception times. The range between the mobile device and the transmitter may be based on the fit of the expected and measured relative reception times.
