Abstract: Aspects presented herein may improve the accuracy of uplink-based positioning when at least one network entity participating in the uplink-based positioning is operating under an energy saving mode. In one aspect, a network entity receives information indicative of a set of antenna panel configurations for a plurality of network nodes, where the set of antenna panel configurations is associated with a set of energy saving modes. The network entity transmits an indication of one or more UL-SRS transmission parameters for a UE based on the information indicative of the set of antenna panel configurations for the plurality of network nodes. In some examples, each antenna panel configuration in the set of antenna panel configurations may include a number of antennas to be used in an UL azimuth angle measurement and a number of antennas to be used in an UL elevation angle measurement under one energy saving mode.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain a first set of position estimates of the UE based on applying a first positioning model to one or more radio frequency fingerprint positioning (RFFP) measurements. The UE may obtain a second set of position estimates of the UE using a positioning technique that does not use the first positioning model. The UE may transmit a mismatch report, wherein the mismatch report is based on comparing the first set of position estimates with the second set of position estimates.

Abstract: In some implementations, a base device may determine a quali-colocation (QCL) relation between a first wireless reference signal transmitted by a first sidelink (SL) anchor and a second wireless reference signal transmitted by a second SL anchor, wherein: the first SL anchor and the second SL anchor comprise UEs separate from the receiving UE, and the first wireless reference signal and the second wireless reference signal are transmitted for positioning of the receiving UE, performing radio frequency (RF) sensing, or both. The base device may wirelessly send, from the base device to the receiving UE, the mSL-QCL information, wherein the mSL-QCL information is indicative of the QCL relation between the first wireless reference signal and the second wireless reference signal.

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: Disclosed are techniques for wireless communication. In an aspect, a target UE receives zone information associated with a set of zones, the zone information indicating, for each of a plurality of candidate UEs for a sidelink-assisted position estimation procedure of the target UE, a zone identifier of a zone in which the respective candidate UE is located. The target UE selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the zone information. The target UE performs the sidelink-assisted position estimation procedure with at least the selected one or more candidate UEs.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive node activation and configuration in cooperative sensing. A method that may be performed by a sensing management function (SnMF) entity includes receiving a first radio frequency (RF) sensing request, from a first entity, for scanning an environment to detect at least a first object, initiating a first RF sensing session in the environment in response to the first RF sensing request, receiving a second RF sensing request, from a second entity, for scanning the environment to detect at least a second object during the first RF sensing session, accommodating the second RF sensing request using output from the first RF sensing session, wherein the first RF sensing session is ongoing, detecting the first and second objects in the environment, and transmitting information about the detected first and second object to the first and second entity, respectively.
