Abstract: A UE receives, from a BS, information indicating a first TEG delay at the BS for a transmission of a first PRS, a second TEG delay at the BS for a reception of an SRS from the UE, a third TEG delay at the BS for a transmission of a second PRS, a fourth TEG delay at the BS for a transmission of the first PRS and a reception of the SRS from the UE, or a fifth TEG delay at the BS for a reception of the SRS from the UE and a transmission of the second PRS, or any combination thereof. The UE determines a double RTT based on a first PRS timing associated with a reception of the first PRS, an SRS timing associated with a transmission of the SRS, a second PRS timing associated with a reception of the second PRS, and the received information.

Abstract: Disclosed are techniques for communication. In an aspect, a reference device (e.g., gNB or BS) and a BS obtain a configuration of a TDOA procedure including respective PRSs to be transmitted by the reference device and the BS. In an aspect, the reference device and the BS each mute their own transmission while the other device is transmitting its respective PRS. Other aspects are directed to DL-TDOA, UL-TDOA and elliptical positioning techniques.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) transmits an uplink reference signal towards a first reconfigurable intelligent surface (RIS) associated with at least one base station, receives, from the first RIS, a reflection of the uplink reference signal, wherein at least one transmission parameter of the reflection identifies the reflection as the reflection of the uplink reference signal, and enables a distance between the UE and the first RIS to be calculated based, at least in part, on a transmission-to-reception (Tx-Rx) time difference measurement for the UE, the Tx-Rx time difference measurement representing a difference between a transmission time from the UE of the uplink reference signal to the first RIS and a reception time at the UE of the reflection of the uplink reference signal from the first RIS.

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.
