Abstract: In an aspect, a UE and BS communicate data traffic in accordance with a first bandwidth part (BWP) configuration. The BS sends, to the UE in association with communication of a plurality of reference signals for positioning (e.g., PRS, SRS-P, etc.), an indication of a second BWP configuration that includes a different bandwidth than the first BWP configuration. The UE and BS communicate, for a duration of the communication of the plurality of reference signals for positioning, at least the plurality of reference signals for positioning in accordance with the second BWP configuration.

Abstract: Method and apparatus for switching between SS-TWR and DS-TWR. The apparatus reserves resources for transmission of a first SL-PRS in a first time slot. The apparatus transmits, to a second UE, the first SL-PRS within the first time slot. The apparatus receives, from the second UE, a second SL-PRS at a second time based on the first time slot and a response time associated with transmission of the second SL-PRS in response to the first SL-PRS. The apparatus measures a time difference between the transmission of the first SL-PRS and reception of the second SL-PRS to determine if a third SL-PRS is to be transmitted to the second UE.

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: Positioning assistance data (PAD) is encoded in positioning System Information Blocks (posSIBs) and periodically broadcast by abase station in a differential manner A PAD element that is different relative to previously broadcast PAD is encoded in a block of posSIB separately from PAD that is unchanged. Another separate block of posSIB includes reference encoding identifying the changed PAD and provides scheduling information. A UE may decode the reference encoding and determine whether the UE has previously decoded the changed PAD. If the UE has previously received the PAD, but has not yet received the new or changed PAD, the UE may receive and decode the block of posSIB with only the changed PAD, thereby increasing efficiency.

Abstract: Aspects presented herein may enable a network entity to configure a group of UEs to simultaneously transmit reference signals and to simultaneously transmit gradient vectors to the network entity, such that the network entity may receive the gradient vectors from the group of UEs as an aggregated gradient vector over the air. In one aspect, a base transmits, to a group of UEs, a configuration that configures the group of UEs to simultaneously transmit one or more group-common reference signals and to simultaneously transmit one or more gradient vectors associated with a federated learning procedure. The network entity receives, from the group of UEs, the one or more group-common reference signals and the one or more gradient vectors based on the configuration via multiple channels. The network entity calculates an average gradient vector based on the one or more group-common reference signals and the one or more gradient vectors.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a communications device determines at least one position estimation performance parameter, determines a zone identifier based at least in part upon the at least one position estimation performance parameter, wherein the zone identifier identifies one of a plurality of zones, and transmits the zone identifier to one or more UEs. A UE receives the zone identifier, determines the at least one position estimation performance parameter, selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the at least one position estimation performance parameter, and performs the sidelink-assisted position estimation procedure of the UE with at least the selected one or more candidate UEs.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) determines a positioning measurement of a first multipath component of a radio frequency (RF) signal transmitted by a transmission-reception point (TRP), determines a first additional positioning measurement of a second multipath component of the RF signal, determines a second additional positioning measurement of a third multipath component of the RF signal, and transmits a measurement report to a location server, the measurement report including at least the positioning measurement, the first additional positioning measurement, the second additional positioning measurement, and one or more parameters associated with the first additional positioning measurement and the second additional positioning measurement.

Abstract: A method for wireless communication by a receiving device, includes receiving, from a transmitting device, a latent representation of a channel sequence for a wireless signal. A decoder applies a physical propagation channel model to the latent representation to reconstruct the channel sequence for the wireless signal.
