Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process for performing sidelink positioning at a user equipment (UE) includes receiving, at the UE, a resource block including a plurality of sidelink symbols in a slot. The resource block includes a first symbol of the plurality of sidelink symbols with at least a first sidelink positioning reference signal (PRS) resource, a second symbol of the plurality of sidelink symbols with at least a second sidelink PRS resource, and a third symbol of the plurality of sidelink symbols with at least a shared sidelink channel resource comprising a sidelink positioning measurement report. The processor further includes processing, at the UE, at least one resource in each symbol of the plurality of sidelink symbols in the slot.

Abstract: Sidelink based positioning of a user equipment (UE) using multiple sidelink UEs as anchor nodes is based on the synchronization status of available sidelink UEs. The synchronization reference of each available sidelink UE may be determined, for example, and sidelink UEs are selected for sidelink positioning based on their synchronization references. For example, sidelink UEs that have a common synchronization source and/or have higher synchronization priority level may be selected for sidelink positioning over other sidelink UEs. Additionally, the positioning method used for the sidelink positioning session may be selected based on the synchronization quality of each of the sidelink UEs. If each sidelink UE has a synchronization quality within a range, a time synchronization sensitive positioning method may be selected, but if one or more sidelink UEs have a synchronization quality outside the range, a positioning method that is less time synchronization sensitive may be selected.

Abstract: In some implementations, a first user equipment (UE) may send a first message comprising a quality of service (QoS) profile to a second UE. The QoS profile may include a response time requirement for providing positioning information within the positioning session. The first UE may receive a second message from the second UE, the second message comprising an indication of whether the second UE can meet the response time requirement. The first UE may determine resource pool parameters for the positioning session. The resource pool parameters may be based at least in part on the indication of whether the second UE can meet the response time requirement. The first UE may send a third message comprising the resource pool parameters to the second UE.

Abstract: A user equipment (UE) is configured for supporting positioning using sounding reference signal (SRS) periodic burst transmissions that includes a plurality of sets of SRS transmissions, where each set of SRS transmissions includes a repetition of SRS resources. The configuration for the SRS periodic burst transmissions includes a start time for the SRS periodic burst transmissions, a repetition configuration for the SRS resources within each set, and a repetition configuration for the plurality of sets of SRS transmissions. The configuration may be received in a Radio Resource Control (RRC) configuration message or a Medium Access Control-Control Element (MAC-CE) message that activates the SRS periodic burst transmissions, and the SRS periodic burst transmissions may be deactivated with a RRC reconfiguration message or another MAC-CE message.

Abstract: Aspects presented herein may enable a UE to store multiple sets of UE processing capabilities at one or more entities, and to activate one of the stored sets based on the UE's current processing availabilities to improve positioning latency. In one aspect, a UE transmits, to at least one of a second UE, a base station, or a network entity, a plurality of capability sets associated with UE positioning processing, the plurality of capability sets including at least a first capability set corresponding to a first level of the UE positioning processing and a second capability set corresponding to a second level of the UE positioning processing, the first level being different from the second level. The UE transmits, to the at least one of the second UE, the base station, or the network entity, an indication to activate one of the plurality of capability sets for UE positioning.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may determine a downlink (DL) positioning reference signal (PRS) measurement period for measuring and processing DL PRSs transmitted by a base station while the UE is in a radio resource control (RRC) INACTIVE state. While in the RRC INACTIVE state, the UE may measure and process DL PRSs during the DL PRS measurement period. In another aspect, a network entity may receive one or more parameters associated with a capability of a UE to measure and process DL PRSs while the UE is in a RRC INACTIVE state. Based on those parameters, the network entity may determine a DL PRS measurement period to be used by the UE while the UE is in the RRC INACTIVE state. The network entity may send, to the UE, information for determining the DL PRS measurement period.
