Abstract: Aspects presented herein may enable a UE to identify whether images captured by the camera(s) of the UE are spoofed (e.g., are real images or false/manipulated/virtual images, etc.). In one aspect, a UE obtains a set of images associated with a vision-aided positioning session, where the set of images is captured using at least one first camera. The UE detects that at least one spoofing feature is present in the set of images during the vision-aided positioning session. The UE stores or outputs an indication of the at least one spoofing feature based on the at least one spoofing feature being present in the set of images. The UE performs the camera-aided positioning session based on at least one non-spoofing feature, where the at least one non-spoofing feature is different from the at least one spoofing feature.

Abstract: A method, for providing a virtual positioning signal measurement, includes: determining that an expected positioning signal measurement is absent from a plurality of actual positioning signal measurements made by a UE; and providing a virtual measurement value, for the expected positioning signal measurement, based on at least one actual positioning signal measurement that is of a same type as the expected positioning signal measurement and that corresponds to at least one positioning signal measured by the UE.

Abstract: Aspects presented herein may enable a navigation application of a UE to feed its calculated navigation route information to a PE of the UE to aid the PE computing positioning estimations to improve positioning accuracy. In one aspect, a UE estimates a current location of the UE based on a set of positioning measurements and time update predictions using a positioning engine. The UE calculates real-time navigation route information using at least one navigation application based on the current location of the UE, a destination of the UE, and map information. The UE changes or verifies a set of positioning estimations performed by the positioning engine based on the real-time navigation route information from the at least one navigation application.

Abstract: Techniques are provided for utilizing reference signals transmitted by network stations to determine the orientation of a wireless node. An example method for determining an orientation of a user equipment includes determining a first location associated with the user equipment, determining a second location associated with a first wireless node, receiving, with the user equipment, a radio frequency signal transmitted from the first wireless node, determining two measurements based at least in part on the first location, the second location, and angle of arrival information associated with the radio frequency signal, determining a gravity vector based on inertial measurements obtained with the user equipment, and computing the orientation of the user equipment based at least in part on the gravity vector and the two measurements.

Abstract: Techniques for Ultra Wide-Lane (UWL) Real-Time Kinematic (RTK) positioning a mobile device may include obtaining, using a multi-band GNSS receiver of the mobile device: a first carrier-phase measurement of a first GNSS signal on a first GNSS carrier frequency, and a second carrier-phase measurement of a second GNSS signal on second GNSS carrier frequency. Techniques may further comprise providing a position estimate of the mobile device, wherein: the position estimate is determined from a wide-lane (WL) combination of the first carrier-phase measurement and the second carrier-phase measurement, and the WL combination has a combined carrier phase noise that is less than a pseudo-range noise of the first carrier-phase measurement and a pseudo-range noise of the second carrier-phase measurement.
