Abstract: An RF sensing method includes: producing, at an application device, an RF sensing request including a request for a network entity to coordinate RF sensing of at least one of a region or an object, wherein the RF sensing request includes at least one criterion of the RF sensing, the at least one criterion comprising at least one of an indication of the region, an identity of at least one RF sensing device, or an identity of a target object of the RF sensing; sending the RF sensing request from the application device to the network entity; and receiving, at the application device from the network entity, an RF sensing report indicating a result of the RF sensing.

Abstract: A first network node may transmit, to a second network node, first information associated with granular user consent control. The first information may be further associated with a data processing task and a UE. The second network node may receive, from the first network node or the UE, second information associated with the granular user consent control. The second information may be further associated with the data processing task and the UE. The second network node may identify a user consent result associated with the data processing task and a user of the UE based on the granular user consent control. The user consent result may be further based on the first information or the second information. The second network node may transmit, to the first network node, the user consent result. Thereafter, the first network node may handle the data processing task based on the user consent result.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: Positioning of a user equipment (UE) is supported using reception points (RPs) that receive uplink sounding reference signals (SRS) from the UE. The RPs may measure signal strengths of received SRS that are used to determine path loss reference values that are provided to the UE for configurating subsequent SRS. The UE may report a plurality of RxTx time difference measurements with respect to a single PRS for the SRS transmitted to a plurality of RPs. The RPs may provide an Rx time for received SRS, which is used to generate a RxTx time different measurement for asymmetric round trip time (RTT) if the RP and TRP clocks are synchronized. The RPs may provide an RxRx time difference measurement for a time of reception of PRS and SRS if the RP and TRP clocks are synchronized. A location server determines a position of the UE using different positioning measurements.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity, obtains first timing information that is associated with a first time-of-arrival (TOA) measurement of a first reference signal for positioning (RS-P) as communicated between a target user equipment (UE) and a base station with a first time basis, obtains second timing information that is associated with a second TOA measurement of a second RS-P as communicated between the target UE and a reference UE associated with a known location and having a second time basis that is different than the first time basis, determines a bias between the first time basis and the second time basis, and determines a position estimate of the target UE via a time differential of arrival (TDOA) positioning technique based at least in part upon the first timing information, the second timing information, and the bias.

Abstract: Aspects of sensor activation or deactivation for positioning a mobile device in a wireless communication network are disclosed. These aspects include, during a positioning session between the mobile device and a location server, determining with the location server that a first trigger condition or a second trigger condition has been met regarding reporting, by the mobile device to the location server, of sensor data from one or more sensors of the mobile device, where: the first trigger condition may comprise a trigger condition for activating the reporting, and the second trigger condition may comprise a trigger condition for deactivating the reporting. Aspects further include sending, from the location server to the mobile device, a message may comprise either: instructions to activate the reporting responsive to determining the first trigger condition has been met, or instructions to deactivate the reporting responsive to determining the second trigger condition has been met.

Abstract: In an aspect, a network component (e.g., BS, server, etc.) obtains measurement information associated with uplink signal(s) from UE(s), with the uplink signal(s) having reciprocity with one or more downlink beams of wireless node(s) (e.g., TRP, reference UE, etc.). The network component determines (e.g., generates or refines) a meausrement (e.g., RFFP-P) model based on the measurement information. The network component provides the measurement (e.g., RFFP-P) model to a target UE. The target UE receives at least one signal (e.g., PRS) on the one or more downlink beams from the wireless node(s). The target UE processes the at least one signal (e.g., predicts target UE location) based at least in part on the measurement (e.g., RFFP-P) model.

Abstract: In an embodiment, a wireless node (e.g., UE or BS) receives from a network component (e.g., BS or core network component) a request for a positioning estimate of a UE associated with a specified time. The wireless node performs positioning measurements at a plurality of times, and determines (e.g., via interpolation or extrapolation) the positioning estimate associated with the specified time based on the positioning measurements. The wireless node transmits, to the network component, a report comprising the determined positioning estimate.
