Abstract: Aspects presented herein may improve/enhance camera-aided/assisted positioning by utilizing light and shadow created by an artificial light. In one aspect, a UE captures a set of images of an object using at least one camera. The UE estimates a direction of at least one light source based on a shadow of the object in the set of images, wherein the shadow of the object is created by the at least one light source. The UE calculates at least one of (1) a distance (d) between the at least one camera and a set of first features associated with the object based on the estimated direction of the at least one light source or (2) directional information of a set of second features associated with a surrounding environment that is within a threshold distance of the object.

Abstract: An example method of position information authentication for a location application performed by a UE, the method comprising determining by a position engine, a position estimate of the UE and determining by the position engine, a position report message indicating the position estimate. The method also comprises determining by a security module, a digital signature generated using a first private key known to the UE and the position report message. The method further comprises transmitting the position report message associated with the digital signature to a location application executed by the UE or another device, wherein the location application is configured to provide one or more location-based services to the UE using the position estimate responsive to a successful authentication of the position report message using the digital signature generated based on the first private key.

Abstract: A mobile device may be configured to improve measurement of carrier phase (CP) in received satellite signals for satellite positioning system (SPS) operations. For example, this may enable an SPS receiver to measure CP of at least a first positioning signal of a first frequency band and a second positioning signal of a second frequency band each received from the same satellite vehicle. A corrected CP of the first positioning signal may be estimated based on the measured CP of the first positioning signal and on the measured CP of the second positioning signal.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine location relative to a roadside unit (RSU) or other nearby point of reference. Vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate to a roadside unit, through the use of broadcast or other messages sent by the vehicles and/or the RSU may share carrier GNSS phase measurement data, wherein the shared GNSS carrier phase measurement data may be utilized to control and coordinate vehicle movements, velocity and/or position by the RSU and/or to determine location of each vehicle relative to the RSU and/or to other vehicles or determine the absolute location of each vehicle. An RSU may coordinate vehicle access to an intersection, manage vehicle speeds and coordinate or control vehicle actions such as slowing, stopping, and changing lanes or sending a vehicle to a particular location.

Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.
