Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may activate an independent synchronization source mode based on one or more conditions associated with the first device. The independent synchronization source mode may correspond to the first device operating as reference for synchronization. The first device may transmit one or more synchronization signals indicating a device type of the first device and indicating that the first device is operating as the reference for synchronization. For example, the first device may select one or more bits or an identifier corresponding to the device type to include in the one or more synchronization signals. A second device receiving the one or more synchronization signals may select the first device as a reference for synchronization based on the device type. The second device may synchronize with the first device using the synchronization signal.

Abstract: Some aspects described herein relate configuring resources in one or more slots for communicating a sidelink synchronization signal (SLSS) while maintaining a logical numbering of multiple consecutive slots including the one or more slots. Based on configuring the at least one slot a SLSS can be received from a node or transmitted to one or more nodes during at least one slot of the one or more slots.

Abstract: Certain aspects of the present disclosure provide techniques for inter-user equipment (UE) coordination. A method, performed by a second UE, includes transmitting, to a first UE, a request for inter-UE coordination information, receiving a first indication from the first UE indicating a first set of resources for one or more transmissions by the second UE based on the request for inter-UE coordination information, and transmitting, based on the received first indication of the first set of resources, the one or more transmissions using a second set of resources.

Abstract: The apparatus may be a UE configured to measure a CBR for a set of resources for SL transmissions, the set of resources for SL transmissions comprising resources in a plurality of carriers. The apparatus may further be configured to evaluate a CR for the set of resources for SL transmissions, the CR being associated with at least one planned SL transmission in the set of resources for SL transmissions. The apparatus may also be configured to adjust, based on the measured CBR and the evaluated CR, the at least one planned SL transmission in the set of resources for SL transmissions.

Abstract: A user equipment (UE) monitors at least one resource subset in a set of resource subsets configured for random selection of a SL transmission resource. The UE selects, based on the monitoring of the at least one resource subset, a resource subset in the set of resource subsets configured for the random selection of the sidelink transmission resource. The UE transmits a sidelink message in a randomly selected transmission resource within the selected resource subset.

Abstract: Aspects of the disclosure provide techniques for applying redundancy mitigation rules when transmitting sensor data sharing messages. A method, performed by a sidelink user equipment (UE), includes observing, via one or more sensors, a set of objects in an environment in which the sidelink UE is operating, applying one or more redundancy mitigation rules to the set of objects, determining, from the set of objects, a number of objects to be shared with one or more other sidelink UEs after the one or more redundancy mitigation rules have been applied to the set of objects, determining, based on the determined number of objects to be shared, whether to transmit a sensor data sharing message (SDSM) to the one or more other sidelink UEs indicating the objects to be shared from the set of objects, and taking one or more actions based on the determination of whether to transmit the SDSM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, via sidelink communication, an inter-UE coordination request message requesting coordination information associated with selecting a first resource for transmitting data. The UE may transmit, based at least in part on receiving a negative acknowledgement associated with the inter-UE coordination request message or based at least in part on not receiving feedback associated with the inter-UE coordination request message within a time period, the data via a second resource that is selected based at least in part on sensing information obtained by the UE. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for selecting a resource for a transmission of a self-contained inter-UE coordination message, wherein the configuration indicates an initial time interval, a step size for incrementing the initial time interval, and an available resource ratio associated with a resource selection window, and wherein the initial time interval is incremented by the step size until a quantity of available resources within the resource selection window satisfies the available resource ratio. The UE may select, based at least in part on the configuration, the resource for the transmission of the self-contained inter-UE coordination message from the quantity of available resources within the resource selection window. The UE may transmit the self-contained inter-UE coordination message via the selected resource. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive signaling indicating one or more resource reservation rules associated with transmitting a sidelink message that includes reservation information associated with one or more sidelink resources. The first UE may determine, based on the one or more resource reservation rules, to include the sidelink message in a physical layer control signal, or a medium access control layer control signal, or both. The first UE may then transmit, to a second UE, the sidelink message in the physical layer control signal, or the medium access control layer control signal, or both based on the determining.
