Abstract: A method of wireless communication at a UE is disclosed herein. The UE obtains, via an antenna of the UE, a first indication of a first measurement of at least one RF signal at a first time instance. The UE obtains, via the antenna, a second indication of a second measurement of the at least one RF signal at a second time instance. The UE calculates a distance traveled by the UE between the first time instance and the second time instance. The UE calculates a DOA of the at least one RF signal based on the first measurement, the second measurement, and the distance traveled by the UE between the first time instance and the second time instance. The UE outputs a third indication of the calculated DoA of the at least one RF signal.

Abstract: A multipath condition detection method includes: determining a first signal quality value corresponding to a first wireless signal, of a first frequency and from a signal source, received by a receiver of a mobile device; determining a second signal quality value corresponding to a second wireless signal, of a second frequency that is different from the first frequency, received by the receiver; and determining whether at least one difference value, corresponding to the first signal quality value and the second signal quality value, is indicative of the mobile device being in a multipath condition with respect to the signal source.

Abstract: Aspects presented herein may enable a UE to improve (e.g., reduce) the convergence time for vision-aided positioning by enabling the UE to use images embedded with location information. In one aspect, a UE receives, from a reference device, a server, or a map, a list of visual features and a location for each visual feature in the list of visual features. The UE identifies at least one visual feature in an area via at least one camera, where the at least one visual feature is included in the list of visual features, where the area is within a threshold distance of the UE. The UE estimates a position of the UE based on the identified at least one visual feature in the area and the location corresponding to the at least one visual feature.

Abstract: Techniques for precise positioning using differential carrier phase (DCP)-based measurement updates are disclosed. The techniques can include obtaining a pseudorange observation for a positioning epoch and a carrier phase observation for the positioning epoch based on measurements of global navigation satellite system (GNSS) signals transmitted by one or more space vehicles (SVs) of a GNSS constellation, generating a differential carrier phase observation for the positioning epoch based on the carrier phase observation for the positioning epoch and a determination that real-time kinematic (RTK) correction data associated with the GNSS constellation is unavailable, and generating a position, velocity, and time (PVT) observation of the mobile device for the positioning epoch based on the differential carrier phase observation for the positioning epoch.

Abstract: Aspects presented herein may enable a network entity (e.g., a location server, an LMF, etc.) to generate and configure virtual anchors and/or virtual positioning reference units (VPRUs) for a UE for UE-based positioning. In one aspect, a network entity receives an indication to perform UE-based positioning for a UE. The network entity configures, for the UE, assistance data that includes a list of virtual anchors and a list of VPRUs for the UE-based positioning. The network entity transmits the assistance data including the list of virtual anchors and the list of VPRUs. The network entity may generate the list of virtual anchors based on a location offset to each physical anchor in a set of physical anchors. The network entity may generate the list of VPRUs based on at least one physical PRU.

Abstract: Position, Velocity, and Time (PVT) information of a LEO satellite can be determined by leveraging a known position of a mobile device comprising a terrestrial satellite receiver of the LEO satellite and using range information (range and/or range rate) of the LEO satellite taken at the mobile device. According to some embodiments, this PVT information can be shared by the mobile device with the server and/or other mobile devices, and information from multiple mobile devices can be crowdsourced to determine robust PVT information for a LEO satellite. Once the PVT information is determined, it can be used to subsequently for positioning of the mobile device and/or other mobile devices.

Abstract: Disclosed are techniques for vehicle positioning. In an aspect, a positioning engine aggregator of a host vehicle determines a position estimate of the host vehicle based on one or more position fixes determined by one or more positioning engines of the host vehicle, receives input from a user interface (UI) of the host vehicle to correct the position estimate of the host vehicle, and updates the position estimate of the host vehicle based on the input from the UI.

Abstract: Aspects presented herein may improve the positioning accuracy and latency of a positioning engine that receives at least one position constraint for assisting the positioning. A wireless device obtains an indication of at least one position constraint for a positioning engine. The wireless device detects whether the at least one position constraint exceeds an error threshold based on a set of PR residuals between the wireless device and at least one satellite. The wireless device excludes the at least one position constraint from a calculation at the positioning engine if the at least one position constraint exceeds the error threshold, or includes the at least one position constraint in the calculation at the positioning engine if the at least one position constraint is below the error threshold.
