    Abstract: Proposed are a method by which a first apparatus performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: obtaining a sidelink (SL) discontinuous reception (DRX) configuration including information related to an SL DRX timer; receiving, from a second apparatus through a physical sidelink control channel (PSCCH), second sidelink control information (SCI) and first SCI for scheduling a physical sidelink shared channel (PSSCH); receiving, from the second apparatus through the PSCCH, the second SCI related to groupcast and a medium access control (MAC) packet data unit (PDU); and determining, on the basis of an index of a sub-channel related to the PSSCH and an index of a slot, a physical sidelink feedback channel (PSFCH) resource.

    Abstract: A method by which a first device performs wireless communication, and a device for supporting same are provided. The method may comprise the steps of: transmitting, to a second device, through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for the scheduling of second sidelink control information (SCI) and a physical sidelink shared channel (PSSCH), the first SCI including information related to a frequency resource allocation, information related to a time resource allocation, and information related to the format of the second SCI; and transmitting, to the second device, through the PSSCH, an inter-UE coordination message and the second SCI including a source ID and a destination ID. The inter-UE coordination message can include information related to a preferred resource or information related to a non-preferred resource, and information indicating that the inter-UE coordination message has been transmitted can be included in the first SCI or the second SCI.

    Abstract: Provided are a method of selecting carriers and a device supporting the method. According to one embodiment of the present invention, a method for selecting carriers in a wireless communication system includes: receiving information on carriers and Channel Busy Ratio threshold from a network; selecting at least one carrier of which CBR value is below the CBR threshold; selecting a resource on the selected carrier; and transmitting a medium access control (MAC) packet data unit (PDU) by using the selected resource of the selected carrier.

    Abstract: A method and apparatus for sidelink connection request based on congestion level for establishing a direct connection between wireless devices is provided. A first wireless device triggers a signaling procedure based on a congestion level of at least one carrier, selects a carrier among the at least one carrier, and transmits a message in the signaling procedure on the selected carrier. Upon receiving the message, a second wireless device may perform carrier reselection.
