Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve minor symmetry in positioning solutions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from each of multiple devices that communicate with the UE via one or more sidelink channels, information indicating a buffer status of the device. The UE may transmit, to a base station, a buffer status report that indicates a combined sidelink buffer status for the multiple devices. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating multiplexing SCI-only grant and data-only SPS traffic on sidelink are disclosed herein. An example method for wireless communication at a first UE includes transmitting a sidelink transmission to a second UE at a first resource, the sidelink transmission including data-only traffic and scheduling information corresponding to future data traffic. The example method also includes transmitting a time offset indicator indicating a starting resource of the future data traffic.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink cancellation indication that indicates a set of resources in which to cancel sidelink communications, wherein the set of resources overlaps with at least one of a physical sidelink feedback channel (PSFCH), a gap symbol, or a sidelink synchronization signal block (S-SSB). The UE may perform one or more sidelink cancellation actions associated with the at least one of the PSFCH, the gap symbol, or the S-SSB. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting at least one LBT report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.

Abstract: Certain aspects of the present disclosure provide techniques for improving positioning accuracy of user equipments (UEs) using non line-of-sight (NLOS) positioning reference signals (PRS) and map information. A method that may be performed by a UE includes obtaining map information regarding, at least, one or more reflectors in an environment including at least the UE and another node, detecting at least one positioning reference signal (PRS) transmission that travels one or more non line-of-sight (NLOS) transmission paths in the environment, and participating in a positioning procedure that estimates a position of the UE based, at least in part, on the at least one PRS transmission that travels the one or more NLOS transmission paths and the map information.
