Abstract: Man-in-the-middle attacks on reference signals used for positioning a mobile device in a wireless network can be detected through time and/or angle consistency checks. Time consistency checks may be based on a consistency of peak location and/or power delay profile across multiple reference signals and/or across different signal types, for example. Angle consistency checks may be based on a consistency of an angle at which a reference signal is received across multiple reference signals and/or in comparison with an expected angle, for example. Embodiments may further include reporting detected attacks.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relay user equipment (UE) receives, from a base station, a set of one or more resource pool for positioning (RPP) configurations, each RPP configuration defining one or more RPPs for use by remote UEs served by the relay UE, each RPP comprising resources for positioning, which may include for sidelink positioning. The relay UE assigns, to each of one or more remote UEs, an RPP or a portion thereof according to the RPP configuration. In some aspects, the assignments are orthogonal in time, frequency, or both, to reduce interference between remote UEs during sidelink positioning. In some aspects, the relay UE receives the RPP configuration(s) in response to sending a request for same to the base station, which the relay UE may send in response to receiving a request for positioning resources from one or more of the remote UEs.

Abstract: Techniques for determining reconfigurable intelligent surface (RIS) operation for RIS-assisted position determination of a mobile device in a wireless communications system, according to this disclosure, may comprise determining, for one or more RISs, whether the mobile device is within a near-field operational distance of the RIS based at least in part on a determined near-field operational distance of the RIS, and a relative distance between the mobile device and the RIS. Techniques may also comprise determining an RIS-assisted position of the mobile device based on measurements made by the mobile device of radio frequency (RF) signals reflected from at least one RIS of the one or more RISs. Techniques may also comprise providing the determined RIS-assisted position of the mobile device.

Abstract: Disclosed are systems, apparatuses, methods, and non-transitory media for improving user equipment (UE) positioning by reducing round-trip-time (RTT) measurement errors that may result from clock-drift between network nodes. In some aspects, RTT measurement error can be mitigated through modifications to resource signaling schedules at a UE and/or gNB, for example, based on resource configuration information specifying a time-gap for signaling resource transmission.

Abstract: A method of wireless communication by a base station, jointly processes channel information associated with a user equipment, UE, in order to generate a jointly processed report. The channel information is collected from collocated transmit and receive points, TRPs (604, t1, t2, t3), of the base station. The base station transmits (t5) the jointly processed (t4) report to a location server (112).

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a base station (BS) includes obtaining a resource-level muting bitmap for a reconfigurable intelligent surface (RIS), wherein the resource-level muting bitmap identifies sets of time and frequency resources during which the RIS should be enabled to reflect a transmission beam or disabled from reflecting a transmission beam, and requesting the RIS to be enabled or disabled according to the resource-level muting bitmap.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) transmits a first signal for positioning (RS-P) (e.g., SRS, etc.) on a first link from the UE to a wireless network node (e.g., BS, UE, etc.). The UE receives, from the wireless network node, location assistance data that comprises information that indicates a line of sight (LOS) condition associated with the first link. The UE measures a second RS-P on a second link from the wireless network node to the UE that is reciprocal to the first link. The UE performs one or more positioning measurements, determines a location estimate of the UE, or both, based in part on the reception of the second RS-P on the second link and the indicated LOS condition, the indicated LOS condition associated with the second link based on link reciprocity between the first and second links.
