    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 for performing wireless communication by a first device includes: receiving information related to a time division duplex (TDD) slot configuration, transmitting, to a second device, a sidelink-synchronization signal block (S-SSB), the S-SSB including a sidelink primary synchronization signal, a sidelink secondary synchronization signal, and a physical sidelink broadcast channel, and transmitting, to the second device, a physical sidelink shared channel based on the information related to the TDD slot configuration. Candidate resources to which a bitmap related to a sidelink resource pool is applied (i) are configured based on the information related to the TDD slot configuration and (ii) include one or more slots. Configuration information related to a sidelink symbol included in each of the one or more slots is received, the configuration information including information related to a position of the sidelink symbol configured to be the same for the candidate resources.

    Abstract: Provided is a method for a first device to perform sidelink communication with a second device. The method comprises: determining a first resource for a first sidelink transmission; receiving, from a third device, a SCI including information related to a second resource for a second sidelink transmission; determining to reselect the first resource, based on overlap of the first resource and the second resource and a relationship between a first priority value of the first sidelink transmission and a second priority value of the second sidelink transmission satisfying a pre-configured condition; and transmitting, to the second device, a first PSCCH related to the first sidelink transmission or a first PSSCH related to the first PSCCH, based on a third resource determined by reselecting the first resource, wherein the pre-configured condition includes a condition in which the first priority value is greater than the second priority value.

    Abstract: A method for a first device to perform wireless communication and a device supporting same. The method may include the steps of: receiving, from a base station, a time division duplex uplink-downlink (TDD UL-DL) configuration including information related to a UL resource; receiving, from the base station, information related to the start of sidelink (SL) symbols, information related to the number of the SL symbols, and a bitmap indicating one or more slots included in an SL resource pool; and determining the SL resource pool.

    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.
