Abstract: Disclosed are techniques for training a machine learning model. In an aspect, a user equipment (UE) receives, from a network entity, one or more selection criteria for determining whether the UE is to participate in training the machine learning model, determines whether the UE satisfies the one or more selection criteria during a first period of time, and transmits, to the network entity, after a second period of time, updated parameters for the machine learning model, wherein the machine learning model is updated during the second period of time based on a determination that the UE satisfies the one or more selection criteria.

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: Disclosed are techniques for wireless sensing. In an aspect, a sensing node receives, from a plurality of sensing nodes, a corresponding plurality of sets of points, wherein each point in each set of points of the plurality of sets of points represents a detection of a target object in an environment of the plurality of sensing nodes, and wherein the detection of the target object is based on one or more measurements of one or more sensing signals transmitted by at least one sensing node of the plurality of sensing nodes, and transmits, to a sensing entity, a sensing report indicating a point cloud determined based on the plurality of sets of points, wherein the sensing report further indicates, for each point in the point cloud, identifiers of at least one set of sensing nodes of the plurality of sensing nodes associated with the point.

Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity obtains one or more positioning measurements of one or more reference signals transmitted to a user equipment (UE) by one or more transmission-reception points (TRPs), determines one or more physical locations of the UE based, at least in part, on the one or more positioning measurements and locations of the one or more TRPs, and determines one or more virtual locations of the UE based, at least in part, on the one or more positioning measurements and locations of the one or more TRPs, wherein the one or more virtual locations of the UE are images of the one or more physical locations of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support non-codebook-based precoding based on downlink channel predictions. A user equipment (UE) may receive control signaling indicating a channel state information (CSI) reference signal (CSI-RS) and a sounding reference signal (SRS) resource. The control signaling may instruct the UE to transmit an SRS via the SRS resource. The control signaling may indicate a differential value indicating a time after the SRS resource at which the UE is to predict CSI. The UE may receive, via the CSI-RS resource, a CSI-RS. The UE may transmit, via the SRS resource, the SRS that is precoded based on predicted CSI for a wireless channel resource that occurs in time after the SRS resource. The predicted CSI may be based on the CSI-RS.

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: 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.
