Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), such as an unmanned aerial vehicle (UAV) (e.g., a source UAV), may initiate a unicast link establishment procedure with another UAV (e.g., a target UAV), which may enable the UAVs to communicate according to an air-to-everything (A2X) service type. The source UAV may transmit a direct communication request (DCR) message to the target UAV that includes an application-layer identifier (ID) that is unique to the target UAV. The source UAV may derive the application-layer ID for the target UAV from a UE-specific ID that is unique to the target UAV. Alternatively, the source UAV may transmit a DCR message that excludes target UAV information. Instead, the DCR message may indicate one or more proximity parameters associated with the source UAV. The UAVs may communicate unicast messages via the unicast link according to A2X configurations and communication parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a consistent listen-before-talk (LBT) failure indication that includes a bitmap, wherein a bit in the bitmap corresponds to a resource block (RB) set, and the bit indicates whether the RB set is associated with consistent LBT failure. The UE may perform a sidelink communication based at least in part on scheduling, wherein the scheduling is based at least in part on the consistent LBT failure indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A non-sidelink synchronization signal (SLSS)-transmitting user equipment (UE) may initiate a channel occupancy time (COT) including multiple contiguous slots and a gap slot. The non-SLSS UE may detect an SLSS UE (capable of transmitting sidelink synchronization signal blocks (S-SSBs)) and assume that the gap slot will be filled with an S-SSB. The non-SLSS may transmit a sidelink message during the COT after the gap slot, based on the assumption. Alternatively, based on the SLSS UE indicating that it is capable of transmitting the S-SSB, the non-SLSS UE may schedule transmission of the S-SSB such that the gap slot is filled. If the SLSS UE is incapable of transmitting the S-SSB, the non-SLSS UE may determine a method for transmitting the sidelink message during the already-initiated COT or during another COT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects involve enhancing an inter-user-equipment coordination (IUC) framework to enable user equipment (UE) to perform beam sweeping over the sidelink. Some aspects more specifically relate to fine-tuning beams, such as transmit beams or receive beams, using one or more IUC requests. In some aspects, multiple transmit beams or multiple receive beams may carry respective IUC requests and associated beam signals. In some aspects, one transmit beam or one receive beam may carry an IUC request and associated beam signal, multiple remaining transmit beams or receive beams may carry associated beam signals, and the transmit UE or the receive UE may identify a fine-tuned transmit beam or a fine-tuned receive beam responsive to, based on, or otherwise associated with the IUC request and associated beam signals.

Abstract: Apparatus, methods, and computer-readable media for facilitating a SL communication for mode 2 resource allocation are disclosed herein. An example method includes configuring an inter-UE coordination message associated with sidelink communication with a second UE, the inter-UE coordination message indicating one or more resources for the sidelink communication. The example method further includes transmitting, to the second UE, the inter-UE coordination message via a MAC-CE, the MAC-CE being associated with a PSSCH. The example method further includes transmitting, to the second UE, or receiving, from the second UE, the sidelink communication via a first resource of the one or more resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication, including sidelink beam management responses. In some aspects, a first user equipment (UE) may receive, in one or more mini-slots, one or more sidelink signals of a plurality of sidelink signals (e.g., sidelink reference signal blocks (S-RSBs), sidelink beams, sidelink reference signals, etc.) for sidelink beam management associated with a second UE; and transmit, to the second UE, at least one response associated with at least one sidelink signal of the one or more sidelink signals received. In some aspects, a first UE may transmit, in a plurality of mini-slots, a plurality of sidelink signals; and receive, from one or more other UEs during one or more response occasions associated with the plurality of sidelink signals, one or more responses associated with at least one of the plurality of sidelink signals. Numerous other aspects are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical sidelink shared channel (PSCCH) transmission that uses unlicensed spectrum. The UE may select a resource block (RB) configuration for one or more resource blocks (RBs) that are associated with a physical sidelink feedback channel (PSFCH) transmission, the RB configuration being based at least in part on the unlicensed spectrum. The UE may transmit an acknowledgement (ACK)/negative acknowledgement (NACK) response to the PSCCH transmission based at least in part on using the PSFCH and the RB configuration for the one or more RBs. Numerous other aspects are described.
