Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.

Abstract: One or more anchor nodes, which may be sidelink devices, may transmit positioning reference signals (PRSs) to a wireless device, such as a user equipment (UE). The UE may select one or more PRSs to process based on respective priorities of the PRSs. At least one anchor node may transmit a priority indication including the respective priorities, or the one or more anchor nodes may transmit the PRSs according to a scrambling sequence or pattern to implicitly indicate the respective priorities. The UE may decode one or more PRSs based on the respective priorities.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for determining a joint priority of sidelink and access link (Uu) positioning reference signal (PRS) transmissions in a wireless communication system. A joint priority of a PRS transmission may refer to a priority of the PRS transmission over the entire set of PRS transmissions including sidelink PRS transmissions and Uu PRS transmissions transmitted to a target UE in a sidelink positioning session. In aspects, a joint priority of a sidelink PRS transmission from an anchor UE may be determined with respect to not only other sidelink transmissions, but also with respect to other Uu PRS transmissions from other anchor base stations. Similarly, a joint priority of a Uu PRS transmission from an anchor base station may be determined with respect to not only other Uu transmissions, but also with respect to other sidelink PRS transmissions from other anchor UEs.

Abstract: A positioning signal processing method at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode, during which the user equipment is in an active mode monitoring for a positioning signal measurement trigger signal, and OFF times of the discontinuous reception mode, during which the user equipment is in an inactive mode; receiving a wake-up signal at the user equipment; and determining, at the user equipment, whether to measure a positioning signal based on whether the wake-up signal indicates to implement the active mode during a scheduled discontinuous reception mode ON time or to skip the scheduled discontinuous reception mode ON time.

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: Various aspects of the present disclosure relate to beam management procedures in wireless communications systems. Some implementations of the present disclosure more specifically provide techniques for reporting measurements for proposed beams (such as beams predicted to be the best beams for communications to and from a UE and a network entity) and other beams detected by the UE. The techniques may be used, for example, to identify mismatches between a proposed set of beams and actual best beams for communications to and from a UE and a network entity and allow for the retraining of machine learning models used to identify the proposed set of beams for communications to and from a UE and a network entity.
