    Abstract: Techniques are provided for processing frequency domain non—contiguous positioning reference signals. An example method for determining a time of arrival of a frequency domain non-contiguous positioning reference signal includes receiving the frequency domain non-contiguous positioning reference signal, determining a first estimate of the time of arrival (1204) based on a narrowband processing of the frequency domain non-contiguous positioning reference signal, performing a wideband processing of the frequency domain non-contiguous positioning reference signal based on the first estimate of the time of arrival, and determining a second estimate of the time of arrival (1214) based on the first estimate of the time of arrival and the wideband processing of the frequency domain non—contiguous positioning reference signal.

    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.
