Abstract: Aspects presented herein may improve the performance of positioning devices by enabling the positioning devices to utilize transformed map data with limited third party knowledge of the transformation. Aspects presented herein may enable a positioning device to make the map data from another coordinate system usable for positioning algorithms without knowledge of the transformation. In one aspect, a UE transmits a request for map data based on a first set of coordinates in a first coordinate system. The UE receives the map data based on a second set of coordinates in a second coordinate system, where the first set of coordinates in the first coordinate system is distinct from the second set of coordinates in the second coordinate system. The UE calculates a set of relative distances between the second set of coordinates and one or more objects corresponding to the map data.

Abstract: Disclosed embodiments pertain to combining Reference Signal Time Difference (RSTD) measurements from partial measurement sessions that result when a single measurement session is interrupted by one or more interruption events including Out of Service (OOS) or Inter-Frequency Handover (IFH) events. In some embodiments, first Time Of Arrival (TOA) measurements of cellular signals during a plurality of discontiguous partial measurement sessions separated by one or more interruption events may be obtained. Second TOA measurements based on a reference time source may be obtained for a plurality of the first TOA measurements from at least two partial measurement sessions. A cell associated with a second TOA measurement may be selected as a reference cell and for each non-reference cell associated with a second TOA measurement, a corresponding RSTD measurement may be obtained relative to the selected reference cell.

Abstract: Aspects presented herein may enable an electronic device to determine gyroscope biases and calibrate a gyroscope without a magnetometer or without relying on data generated from a magnetometer. In one aspect, an apparatus estimates a set of gyroscopic biases for a plurality of temperatures or temperature ranges to create a mapping that maps the plurality of temperatures or temperature ranges to the set of gyroscopic biases. The apparatus monitors temperatures of a gyroscope via a gyroscope temperature sensor. The apparatus calibrates the gyroscope in response to the gyroscope changing from a first temperature to a second temperature based on the mapping or based on a predicted value derived from the mapping. In some aspects, the apparatus calculates a DR trajectory of the apparatus based at least in part on the calibrated gyroscope and the accelerometer without using a magnetometer or without using data generated from the magnetometer.

Abstract: A UE includes: at least one sensor configured to provide at least one sensor measurement; and a processor configured to: determine first and second ranges between the UE and a positioning signal source based on first and second positioning signal measurements of first and second positioning signals from the positioning signal source corresponding to first and second times; determine whether a selected range of the first range or the second range is a multipath range based on the first range, the second range, and movement of the UE between the first time and the second time indicated by the at least one sensor measurement; and discount use of the selected range in a positioning technique in response to the selected range being determined to be a multipath range.

Abstract: Disclosed is a method and apparatus for capturing, collecting, and distributing event information displayed on signs. The method may include capturing, by a mobile device, an image of a sign that displays information for an event. The method may also include extracting information for the event from the captured image of the sign, and determining a location of the mobile device when the image of the sign was captured. Furthermore, the method may include uploading, to a server, a time when the image was captured, the information for the event extracted from the captured image, a location of the event determined from extracted event information, a location of the sign, or a combination thereof.

Abstract: Techniques for improved GNSS positioning include leveraging approximate location information and information from sensors of a mobile device, and/or sensors communicatively coupled therewith, to detect obstructions and determine which SVs may be blocked from direct view. In particular, information from one or more cameras, LIDAR, radar, and/or other sensor systems can be used to determine how nearby obstructions may block the view of portions of the sky from the perspective of the mobile device, then compared with a SkyPlot of SVs based on the mobile device's approximate location to determine which SVs are likely blocked from view. A GNSS position determination of the mobile device can then be made by reducing the weight of information received from blocked (obstructed) SVs.

Abstract: Techniques disclosed herein help a location server identify inaccuracies in a list of neighboring cells provided by the location server by enabling mobile devices to, during an OTDOA session to opportunistically take Reference Signal Time Difference (RSTD) measurements of additional cells not on the neighboring cell list. The mobile device can then provide these RSTD measurements back to the server, which can optimize its algorithm for determining neighboring cells based on these measurements.

Abstract: A user equipment (UE) is preconfigured with Positioning Reference Signal (PRS) configurations for a plurality of base stations. The UE receives a base station almanac including position information and identifies of local base stations. Using the PRS configurations and information from the base station almanac, the UE receives PRS signals from a first set of base stations. The UE may also receive cell-specific reference signals (CRS) from a second set of base stations. The UE performs location determination for the user equipment using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.
