    Abstract: This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

    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: Techniques described herein may enable more accurate location of a user equipment (UE) that may be subject to movement or velocity. The UE may obtain, during a period of time, location-related measurements of RF signals received at the UE, where the location-related measurements are indicative of a location of the UE during the period of time; The UE may also obtain, using sensors of the UE, velocity-related measurements indicative of a movement or velocity of the UE during the period of time. The UE may send the location-related measurements and the velocity-related measurements to a location server, which may compute a location of the UE based on the measurements. The location computation may allow for movement of the UE during the period of time.

    Abstract: Methods, apparatuses and/or articles of manufacture, which may be employed in a mobile device and/or in a location server, enable acquisition assistance at the mobile device. In at least one implementation, which is not intended to limit claimed subject matter, acquisition assistance may include expected Doppler frequency shift and expected code phase in the case of a particular Global Navigation Satellite System (GNSS) satellite vehicle, as well as a search window for each of these, and a confidence value. The confidence value may indicate the likelihood of detecting signals from the satellite vehicle at the current expected location of the mobile device and within the given search windows and may enable one or more of faster location estimation, reduced battery consumption, and detection of weaker satellite signals.

    Abstract: Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning for a target device includes exchanging positioning messages that support a plurality of positioning methods between the target device and a location server. The positioning message may include common parameters applicable for all positioning methods. One of the positioning messages may be a Request Assistance Data message to request assistance data for a first positioning method, wherein the common parameters for the Request Assistance Data message includes an approximate location of the target device determined using a different positioning method. Another positioning message may be a Provide Assistance Data message to provide assistance data that is not in response to a request for assistance data, wherein the common parameters for the Provide Assistance Data message may include an approximate location of the target device or a current time.
