Abstract: A user equipment (UE) obtains assistance data for positioning from one or more sidelink connected UEs. Prior to sending the assistance data for positioning to the UE, the sidelink UE(s) revises the assistance data, e.g., by reprioritizing, reordering, or reducing the assistance data, or a combination thereof. By revising the assistance data the sidelink UE(s) provides the most pertinent assistance data to the UE, thereby increasing power savings for the UE. Where multiple sidelink UEs provide revised assistance data to the UE, the UE combines the revised assistance data, e.g., based on measurement information, range information, or priority of the sidelink UEs. If the UE has a connection to the location server, the UE obtains revised assistance data from sidelink UE(s) to avoid the need for an assistance data exchange with the location server during the positioning session, thereby improving latency.

Abstract: In an embodiment, a UE transmits an on-demand PRS request for PRS(s) on selected frequency-domain resource(s) (e.g., frequency layer, frequency band, CC, etc.). In another embodiment, a UE receives, from a network component (e.g., BS, core network component, LMF, location server, etc.), configuration of frequency-domain resources (e.g., frequency layer, frequency band, CC, etc.), wherein each frequency-domain resource configuration is associated with a bandwidth and SCS. The UE further receives, from the network component, configuration of PRS(s), wherein each PRS is associated with a single frequency-domain resource from the frequency-domain resources. The UE determines a single reference TRP for each of the frequency-domain resources, performs PRS measurements on the PRS(s), and determines positioning measurements at least based on the PRS measurements and the determined reference TRPs.
