Abstract: Methods, systems, computer-readable media, and apparatuses are described for reporting, in support of positioning a UE, information about consistencies of positioning reference signal (PRS) measurements, PRS resources, PRS resource sets, or transmission and reception points (TRPs). In some embodiments, a UE receives PRS resources from TRPs and performs PRS measurements based on the PRS resources. The UE determines whether certain PRS measurements, PRS resources, PRS resource sets, or TRPs contribute to a consistent position estimate and/or consistent positioning measurements. The UE reports to a device, such as to a location server, information about consistent groups, where each consistent group identifies a set of such consistent elements.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may explicitly or implicitly identify one or more parameters associated with a user equipment (UE), and may classify the UE into a cluster of UEs based on identifying the one or more parameters. The base station may determine a customized function block based on classifying the UE into the cluster of UEs. For example, the base station may determine the customized function block based on determining whether the cluster of UEs is associated with a pre-trained customized function block. The base station may then transmit the customized function block to the UE. The UE may receive the customized function block and may process one or more signals at the UE based on the received customized function block.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a communications device (e.g., UE, gNB, LMF, etc.) determines a reference geographic coordinate (e.g., local or global coordinate) for a plurality of sidelink zones, wherein boundaries associated with each sidelink zone are defined via a respective sidelink zone identifier that includes one or more geographic offsets relative to the reference geographic coordinate. A UE receives an indication of the reference geographic coordinate, and performs one or more sidelink zone-related operations based on the reference geographic coordinate.

Abstract: Techniques are provided for selecting reference nodes for use in a double difference positioning method. An example method of determining compensation values for positioning reference signals includes receiving positioning reference signal measurements from the one or more reference nodes, and determining one or more compensation values based at least in part on the positioning reference signal measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an anchor node, control information that triggers a UE-specific aperiodic positioning signal. The UE may perform, to the anchor node, the UE-specific aperiodic positioning signal based at least in part on the control information. The UE may transmit, to the anchor node, a response based at least in part on the UE-specific aperiodic positioning signal. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relative location anchor group (RLAG) may facilitate a position estimation procedure in an environment where absolute position estimation accuracy is below a threshold. An absolute position estimate derived via the RLAG may optionally be transformed to a true (or more accurate) position estimate via transformation information. In some cases, new anchors may be added to the RLAG after performing a position estimation procedure with the RLAG. In other designs, a local coordinate system (LCS) may be used for position estimation in lieu of a global coordinate system (GCS), such as WGS 84.

Abstract: Techniques are provided for operating user equipment (UE) in a discontinuous reception (DRX) mode, and more specifically, setting a DRX inactivity timer value. An example method for operating a user equipment in a discontinuous reception mode including an active mode for communicating with a network and an inactive mode when the user equipment does not communicate with the network includes determining a trigger condition based on a communication with the network, determining the inactivity timer value based on the trigger condition, and operating the user equipment in the active mode during a duration of the inactivity timer value and in the inactive mode after the duration of the inactivity timer value.

Abstract: When a user equipment (UE) is configured with a primary cell (PCell) and one or more secondary cells (SCell), scheduling of uplink (UL) and/or downlink (DL) resources for the UE may be received from the primary cell. However, in some circumstances, the primary cell may be unable to provide such scheduling related information. In such circumstances, one or more secondary cells may be enabled to provide scheduling related information to the UE such that cells other than the primary cell may function as scheduling cells. Information regarding dormancy states of the cells (primary and/or secondary) may also be provided by the scheduling cells.
