    Abstract: Certain aspects of the present disclosure provide techniques for improving sidelink positioning via messaging between wireless nodes, e.g., roadside service units (RSUs). A method that may be performed by a user equipment (UE) includes receiving a first positioning reference signal (PRS) from a first wireless node, receiving a second PRS from a second wireless node, receiving, from the first wireless node, an estimate of a first clock error component between the first wireless node and the second wireless node, and estimating a position of the UE, based on the first PRS, the second PRS, and the estimate of the first clock error component.

    Abstract: Certain aspects of the present disclosure provide techniques for determining resources for sidelink communications based on coordination information. A method that may be performed by a first wireless device includes receiving, from second wireless devices, reports indicating coordination information associated with candidate resources and assigning ranks to the reports. The method also includes determining resources from the candidate resources for communicating with third wireless devices based on at least one of: at least two reports, and the ranks of the at least two reports; or at least one of the reports and sensing information, measured by the first wireless device, associated with the candidate resources, and the rank of the reports and a rank of the sensing information. The method further includes communicating with the third wireless devices via the determined resources.

    Abstract: Certain aspects of the present disclosure provide techniques for wireless in-vehicle networking. A method that may be performed by a device in a vehicle includes wirelessly transmitting a data packet directly via a first device-to-device (D2D) communication link to another device in the vehicle; monitoring for an acknowledgment (ACK) of the data packet; deciding whether to retransmit the data packet to the other device, based on the monitoring; and wirelessly transmitting the data packet to a transmission relay, wherein an intended destination of the data packet is the other device, wherein the monitoring for the ACK comprises monitoring for a first ACK from the other device and a second ACK from the transmission relay.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a sidelink, a groupcast communication and a unicast communication concurrently from a transmitter. The UE may determine a feedback sequence to be transmitted to indicate joint acknowledgment or negative acknowledgement feedback for the groupcast communication and the unicast communication based at least in part on a decoding of the groupcast communication. The UE may transmit the feedback sequence in one or more sidelink feedback resources associated with a sidelink subchannel via which at least one of the groupcast communication or the unicast communication is received. Numerous other aspects are provided.

    Abstract: Techniques and apparatus for managing release of resource reservations for sidelink communications are provided. At least one resource reservation is determined from a resource pool having time-frequency resources allocated for sidelink communications with one or more user equipments. Control information that includes an indication of the at least one resource reservation and an indication of whether the at least one resource reservation is releasable is transmitted. A determination of whether to reclaim the at least one resource reservation is made, based on the control information. A set of resource reservations is selected from the resource pool for sidelink communications, based on the determination.
