    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first vehicle user equipment (VUE) may transmit, to a node, first information associated with a presence of an object in a region of interest based at least in part on a sensing of the region of interest performed by the first VUE. The VUE may receive, from the node, second information associated with the presence of the object in the region of interest based at least in part on a sensing of the region of interest performed by a second VUE. The VUE may determine whether the object is present in the region of interest based at least in part on the first information and the second information. The VUE may perform an action based at least in part on whether the object is present in the region of interest. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A device may receive a directional positioning reference signal over one or more beams from another device. The device may transmit a broadcast positioning reference signal in response to receipt of the directional positioning reference signal. The device may receive, from the other device, a report including timing and directionality associated with transmission of the directional positioning reference signal. The report may also include timing and directionality associated with receipt of the broadcast positioning reference signal at the other device. Responsive to receipt of the report, the device may transmit beam specific measurement information associated with the one or more beams to the other device. The device may communicate with the other device using a beam of the one or more beams based at least on the report and the beam specific measurement information.

    Abstract: Independent ranging sessions that are initiated by multiple initiating user equipments (UEs) are detected and combined into a single combined ranging session to reduce overhead. The independent ranging sessions may be determined to be nearby and concurrent when a UE detects a number of ranging cycles within a predetermined time. The UE may send messages to each initiator UE indicating that the ranging sessions should be combined and the initiator UEs will terminated initiating any further ranging sessions. Combined ranging session may be initiated by the UE and may include all of the participating UEs from the independent ranging sessions. The combined ranging session continues until it is determined that one or more UEs in the combined ranging session are not receiving ranging signals from other UEs.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a recipient user equipment (UE) of a sidelink resource sharing system may receive, from a plurality of provider UEs, resource information associated with the plurality of provider UEs; select, based at least in part on a ranked order and the resource information, one or more resources associated with one or more selected UEs, of the plurality of provider UEs, wherein the ranked order is based at least in part on measurement information, determined by the recipient UE, associated with the plurality of provider UEs; and perform a sidelink communication using the one or more resources. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. To support adaptive quantization level selection in federated learning, a server may cause a base station to transmit an indication of a quantization level for a user equipment (UE) to use to compress gradient data output by a machine learning model. For example, the server may determine, for each UE of a set of UEs, a respective quantization level for respective gradient data that is output by a respective machine learning model at each UE. The server may transmit, to each UE via one or more base stations, first information for use as an input in the respective machine learning model and an indication of the respective quantization level. A UE may receive the first information and the indication and may transmit, to the server, compressed gradient data that is generated based on (e.g., using) the indicated quantization level.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a plurality of UEs for a UE positioning session. The UE may identify a set of parameters for the UE positioning session. The UE may broadcast information indicating at least the set of parameters for the UE positioning session. The UE may receive, from at least one of the plurality of UEs, a set of positioning reference signals (PRSs) based at least in part on the set of parameters. The UE may broadcast, based at least in part on the set of PRSs, positioning information. Numerous other aspects are provided.
