Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication or follow rules to determine whether to enter or skip a measurement gap. The measurement gap may be a scheduled gap in data communications in order for the UE to measure one or more reference signals. The UE may enter or skip the measurement gap based at least in part on the determination. Numerous other aspects are provided.

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: Positioning of a target user equipment (UE) using a mobile anchor node is supported by providing motion information for the mobile anchor node and/or measurement restrictions. The target UE receives motion information for the mobile anchor node, which may be an ordered list of points or, e.g., a motion path. The target UE may generate positioning measurements using the motion information for the mobile anchor node to determine the position of the mobile anchor node when it transmits positioning reference signals (PRS). The target UE may receive an indication of position measurement restriction if the mobile anchor node is moving. The target UE may receive PRS over a plurality of PRS occasions. The target UE may restrict measurement to only one PRS occasion, may generate and separately report measurements for each PRS occasions or may combine a plurality of measurements using filter coefficients provided by a location server.

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 various techniques for wireless communication, and in particular, carrier-phase based positioning. In an aspect, a position estimation entity may obtain a first differential measurement based on measurement of a first set of positioning reference signal (PRS) resources by a first node and measurement of a second set of PRS resources by a second node, wherein the first set of PRS resources are phase-coherent with the second set of PRS resources. The position estimation entity may obtain a second differential measurement based on measurement of a third set of PRS resources by the first node and measurement of a fourth set of PRS resources by the second node, wherein the third set of PRS resources are phase-coherent with the fourth set of PRS resources. The position estimation entity may determine a positioning estimate of a target node based on the first differential measurement and the second differential measurement.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity provides assistance data to sidelink anchors and a UE. The assistance data may include a set of proximity-based sidelink positioning reference signal (PRS) pre-configurations for on-demand PRS position estimation. The target UE transmits a sidelink PRS trigger to trigger an on-demand sidelink PRS position estimation session with a dynamic sidelink anchor group, the sidelink PRS trigger configured to indicate a sidelink zone associated with the UE and a proximity requirement for participation in the on-demand sidelink PRS position estimation. At least one sidelink anchor determines that the proximity requirement to the sidelink zone is satisfied, selects a proximity-based sidelink PRS pre-configuration based on a dynamic proximity to the sidelink zone, and performs a sidelink PRS exchange with the UE.

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.
