Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives positioning reference signal (PRS) resources of a PRS instance, receives at least one symbol of a high priority downlink channel scheduled during a PRS processing window for the PRS instance, wherein the high priority downlink channel is determined to have high priority based on the high priority downlink channel being associated with a high priority uplink channel, and refrains from processing the PRS resources of the PRS instance during the PRS processing window based on one or more conditions related to prioritizing PRS processing, wherein the one or more conditions indicate that the UE does not expect to process the PRS resources of the PRS instance during the PRS processing window based on the at least one symbol of the high priority downlink channel being scheduled during the PRS processing window.

The wireless device may output at least one of a set of measurements based on the measured set of PRSs, a set of labels associated with the measured set of PRSs, or assistance information associated with the measured set of PRSs for training a positioning model. In one aspect, the wireless device may transmit, to a network entity, the set of measurements for the positioning model. In another aspect, the wireless device may include the positioning model. The wireless device may train the positioning model based on at least one of the set of measurements, the set of labels, or the assistance information. The wireless device may include a user equipment (UE) or a positioning reference unit (PRU). The network entity may include a location management function (LMF).

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode receives, from a location server, an anchor selection update message indicating that the UE has been selected as an anchor UE for a joint positioning session with one or more second UEs, wherein the UE is selected as the anchor UE based at least in part on the UE having DRX active time occasions closer to a plurality of measurement occasions for the joint positioning session than DRX active time occasions of the one or more second UEs, performs positioning measurements for the joint positioning session during one or more measurement occasions that overlap with the DRX active time occasions of the UE, and transmits, to the one or more second UEs, the positioning measurements, a location of the UE determined based on the positioning measurements, or both.

Abstract: A parameter server located at a base station may coordinate federated learning among multiple user equipment (UEs) using over-the-air (OTA) aggregation with power control to mitigate aggregation distortion due to amplitude misalignment. The parameter server may select a first group of UEs for a first OTA aggregation session of a federated learning round based on a common received power property of each UE in the first group of UEs. The parameter server may transmit a global model to the first group of UEs. Each UE in the first group may train the global model based on a local dataset and transmit values associated with the trained local model. The parameter server may receive, on resource elements for the first group of UEs, a first aggregate amplitude modulated analog signal representing a combined response from the first group of UEs.

Abstract: A user equipment (UE) may receive a set of reference signals (RSs) from each of a plurality of network nodes. The set of RSs may include a first subset of RSs from a first network node of the plurality of network nodes and a second subset of RSs from a second network node of the plurality of network nodes. The first subset of RSs and the second subset of RSs may be non-orthogonal relative to one another and may be received during a same time period. The UE may measure the set of RSs from each of the plurality of network nodes received during the same time period. The UE may transmit, for a network entity, positioning information associated with measuring the set of RSs from each of the plurality of network nodes.
