Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a wake up signal to wake up a plurality of second UEs. The wake up signal may be based at least in part on location information associated with the UE, location information associated with one or more of the plurality of second UEs, or a combination thereof. The UE may further transmit, to the plurality of second UEs, the wake up signal. Accordingly, the plurality of second UEs may receive the wake up signal and monitor for messages from the second UE based at least in part on receiving the wake up signal. Numerous other aspects are provided.

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: In some aspects, a method of wireless communication includes performing a full reference signal receive power (RSRP) sweep for a first slot to determine a first resource exclusion RSRP threshold, and performing a resource reevaluation for a second slot based on the first resource exclusion RSRP threshold from the first slot. In some aspects, a method of wireless communication may include performing a full RSRP sweep for a first slot to determine a first resource exclusion RSRP threshold and performing the full RSRP sweep for a second slot that is a number of slots following the first slot to determine a second resource exclusion RSRP threshold. For each slot between the first slot and the second slot, the resource reevaluation may be performed based on the first resource exclusion RSRP threshold determined for the first slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a set of resource maps from one or more second UEs, each resource map of the set of resource maps including resource availability information for a respective time window. The first UE may select a set of resources based at least in part on at least one resource map of the set of resource maps. The first UE may transmit a signal using the selected set of resources. Numerous other aspects are provided.

Abstract: A method for wireless communication performed by a sensing user equipment (UE) includes identifying resource availability during a sensing window. The method further includes receiving a request to share resource information with a transmitter UE. The method still further includes determining a sharing condition is satisfied. The method also includes sharing the resource availability with the transmitter UE based on satisfying the sharing condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, for full-duplex mode communication on a first link and a second link, a timing adjustment to at least one of a first timing or a second timing, wherein the timing adjustment is to cause a delay between clutter reflection from a first signal and an occurrence of a second signal to occur during a cyclic prefix of the second signal; cause the timing adjustment to be applied to the at least one of the first timing or the second timing; and communicate in the full-duplex mode with a first node and a second node in accordance with the timing adjustment, wherein communicating includes transmitting the first signal to the first node and receiving the second signal from the second node. Numerous other aspects are provided.

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: Aspects directed towards reserving resources for sidelink communications are disclosed. In one example, an initial sidelink communication is transmitted which includes an indication of resources reserved for a subsequent sidelink communication. A transmission restriction is applied for the subsequent sidelink communication based on a transmission characteristic associated with transmitting the initial sidelink communication. The subsequent sidelink communication is then transmitted according to the transmission restriction.
