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.

Abstract: In an embodiment, a UE determines a maximum duration to which a UE shall remain active after a DRX ON period to transmit and/or process one or more reference signals for positioning associated with a positioning session. The UE transmits an indication of the maximum value to a BS. The UE and the BS each selectively transmit and/or process the one or more reference signals (e.g., DL PRSs and/or UL SRS-Ps) based at least in part upon the maximum duration.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine, concurrent with reading of one or more system information blocks (SIBs) of a first frequency, acquisition information for a second frequency. In some aspects, the wireless communication device may perform a reading of one or more SIBs associated with the second frequency based on determining the acquisition information for the second frequency and to cause the wireless communication device to camp on a cell associated with the second frequency. Numerous other aspects are provided.

Abstract: In an aspect, a user equipment (UE) may receive at least one discontinuous reception (DRX) configuration, wherein the at least one DRX configuration indicates at least a DRX on-time and a wake-up signal monitoring window for reception of a wake-up signal, wherein the wake-up signal is configured for use in determining whether the UE is to wake-up for sidelink positioning operations. The UE may transition from a sleep state to a wake-up state during the DRX on-time to conduct one or more sidelink positioning operations dependent on whether the wake-up signal is received during the wake-up signal monitoring window.

Abstract: Aspects presented herein may enable a UE to communicate with NTN base station(s) more efficiently to improve NTN positioning. In one aspect, a UE communicates with at least one TN base station via a first set of PFLs for a UE positioning session. The UE communicates with at least one NTN base station via a second set of PFLs for the UE positioning session, the second set of PFLs being different from the first set of PFLs. In another aspect, a UE measures a first RS that is transmitted from a base station via a wide beam, the wide beam having a coverage over an area. The UE measures at least one second RS that is transmitted from the base station via at least one narrow beam based on the first RS being successfully decoded, each of the at least one narrow beam covering a portion of the area.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to determine a location of a device using carrier phase positioning. A process includes transmitting, at the device to a network entity, a phase measurement capability of a device (e.g., a user equipment (UE)) for subcarrier set pairs of different resources received by the device. The different resources are associated with a reference signal. The process can include receiving, at the device, a phase measurement request from a network entity for configuring phase measurements of the subcarrier set pairs of the different resources. The process can include transmitting a phase measurement report to the network entity based on the phase measurement request, the phase measurement report including information associated with a measured phase difference of at least one subcarrier set pair associated with the different resources.

Abstract: A method of wireless communication performed by a user equipment (UE) is disclosed and includes determining a position of the UE based on a first positioning synchronization source; pre-configuring a first sidelink coordination group for use by the UE prior to an occurrence of one or more first triggering events, wherein the first sidelink coordination group uses a second positioning synchronization source that is different than the first positioning synchronization source; and in response to a determination that the one or more first triggering events has occurred, transitioning to use of the first sidelink coordination group for determining the position of the UE.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may obtain a configuration that defines a first number of positioning measurement transmission beams, each positioning measurement transmission beam associated with a boresight transmission angle of the UE, and a second number of positioning discovery transmission beams, each positioning discovery transmission beam associated with a boresight transmission angle of the UE. The UE may transmit the positioning discovery transmission beams, then receive, from at least one other UE, feedback related to at least one of the positioning discovery transmission beams, and, based on that feedback, determine a subset of the positioning measurement transmission beams to be used for performing positioning measurements. The UE may perform the positioning measurements using the subset of the positioning measurement transmission beams.
