    Abstract: Aspects presented herein may enable a UE to verify the integrity of map data, thereby improving the accuracy and safety of map-aiding positioning and/or map-based positioning. In one aspect, a UE performs a map-aiding positioning based on a first set of map data. The UE verifies whether an integrity of the first set of map data meets an accuracy threshold. The UE discards the first set of map data if the verification of the integrity of the first set of map data does not meet the accuracy threshold. For example, the UE may compare the first set of map data with a second set of map data from a different source, and identify the integrity of the first set of map data does not meet the accuracy threshold if the comparison shows an indication of inconsistency above a consistency threshold.

    Abstract: A method for determining a tunnel exit of a user equipment, includes: determining a tunnel entry of the user equipment; determining that the user equipment is receiving signals from one or more satellite vehicles; determining whether one or more parameters based on the signals received by the user equipment indicate a line of sight between the user equipment and the one or more satellite vehicles; and determining no tunnel exit of the user equipment in response to determining that the one or more parameters indicate no line of sight between the user equipment and at least one of the one or more satellite vehicles.

    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: 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.
