Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) measures, during a measurement period that spans multiple measurement opportunities, multiple positioning reference signal (PRS) instances, each PRS instance occupying a different measurement opportunity, to produce a plurality of positioning measurements. A PRS instance can be a PRS resource, a PRS resource set, a PRS frequency layer, a transmission/reception point, or combinations thereof. For each PRS instance measured, the UE determines whether the PRS instance was punctured. Upon a determination that the PRS instance was punctured, the UE discards at least a portion of the positioning measurement and modifies the measurement period, e.g., by restarting the measurement period or extending the measurement period in order to take a measurement of another PRS instance.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving base station via higher layer signaling, a plurality of measurement gap configurations, receives, from the serving base station via lower layer signaling, an activation of a first measurement gap configuration of the plurality of measurement gap configurations, and performs one or more measurements of one or more non-serving base stations during measurement gaps specified by the first measurement gap configuration. Other techniques related to dynamic configuration of measurement gap configurations are also disclosed.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs. The UE may send, to a serving base station, a request to use a first MG configuration from the plurality of MG configurations, and may receive a response to the first request. The UE then measures positioning signals using an MG configuration indicated by the response. Based on measurements of the first set of positioning signals, the UE may select a second MG configuration, send a second request to use the second MG configuration, and receive a response to the second request. The UE then measures a second set of positioning signals using an MG configuration indicated by the response to the second request.

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 measurement (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: A user equipment (UE) may define the classes of a plurality of path delay detection algorithms that the UE may use to identify line-of-sight positioning signals and reject non-line-of-sight positioning signals. The UE may receive a capabilities request from a location server and transmit, to the location server, a capability report indicating the classes of the plurality of path delay detection algorithms supported by the UE. The UE receives a location information request from a location server, and selects a path delay detection algorithm, which is used to perform measurements of one or more positioning signals received by the UE. The UE provides an indication of the selected path delay detection algorithm along with the positioning measurements to the location server. The location server determines or verifies a location of the UE based on the path delay detection algorithm selected by the UE and the positioning measurements.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving, from a network device, a request to initiate gradient computations for a round of federated learning. The method also includes computing gradients in response to receiving the request to initiate gradient computation. The method further includes informing the network device of availability of the gradients. The method still further includes receiving, from the network device, information to enable transfer of the gradients to the network device. The method further includes transferring the gradients to the network device in response to receiving the information to enable transfer.
