Abstract: Proposed are a method by which a first device performs wireless communication and a device supporting same. For example, the first device may receive, from a second device, an RRC message including information related to whether inter-user equipment (UE) coordination capability is supported. For example, the first device may transmit an inter-UE coordination request MAC CE to the second device, on the basis of the information related to whether the inter-UE coordination capability is supported indicating that the inter-UE coordination capability is supported. For example, the first device may receive, from the second device, inter-UE coordination information including information related to a preferred resource or information related to a non-preferred resource. For example, the first device may select an SL resource on the basis of the inter-UE coordination information. For example, the first device may transmit first SCI for scheduling of second SCI and a PSSCH via a PSCCH, on the basis of the SL resource. For example, the first device may transmit the second SCI and a MAC PDU via the PSSCH, on the basis of the SL resource.
