    Abstract: According to an embodiment of the present disclosure, a method for a first device to perform wireless communication is proposed. The method comprises: obtaining a sidelink discontinuous reception (SL DRX) configuration; receiving first sidelink control information (SCI) for scheduling a first physical sidelink shared channel (PSSCH) through a first physical sidelink control channel (PSCCH) from a second device; receiving second SCI and first data from the second device through the first PSSCH; and determining a first physical sidelink feedback channel (PSFCH) resource based on an index of a slot and an index of a subchannel which are related to the first PSSCH, wherein a first timer included in the SL DRX configuration is started based on skipping of a first PSFCH transmission related to the first PSSCH on the first PSFCH resource.

    Abstract: Provided are a method for performing wireless communication by a first device, and a device for supporting the method. The method may comprise: receiving, from a base station, information related to a physical uplink control channel (PUCCH) resource for reporting hybrid automatic repeat request (HARQ) feedback information and information related to a configured grant (CG) resource for sidelink (SL); generating ACK information, based on no physical sidelink control channel (PSCCH) transmission by the first device on the CG resource in a single period; and determining a priority value of the ACK information, wherein the priority value of the ACK information is same as a largest priority value among at least one possible priority value related to the CG resource.

    Abstract: A first device performing wireless communication receives, from a base station, information related to physical uplink control channel (PUCCH) resources and information related to M sidelink (SL) slots; performs N physical sidelink shared channel (PSSCH) transmissions based on N SL slots from among the M SL slots; determines one physical sidelink feedback channel (PSFCH) slot related to the PSSCH transmissions; and in response to the N PSSCH transmissions, receives information on K pieces of SL hybrid automatic repeat request feedback on the one PSFCH slot. The first device transmits information on L pieces of HARQ feedback to the base station based on the PUCCH resources, wherein the one PSFCH slot is associated with L SL slots, M, N, K and L are positive integers, L is greater than or equal to M, M is greater than or equal to N, and N is greater than or equal to K.

    Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method may include receiving information related to a time division duplex (TDD) slot configuration, transmitting, to a second device, a sidelink-synchronization signal block (S-SSB), wherein the S-SSB includes a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS) and a physical sidelink broadcast channel (PSBCH), and transmitting, to the second device, a physical sidelink shared channel (PSSCH) based on the information related to the TDD slot configuration. For example, candidate resources to which a bitmap related to a sidelink resource pool is applied are configured based on the information related to the TDD slot configuration. For example, the candidate resources include one or more slots. For example, configuration information related to a sidelink symbol included in each of the one or more slots is received. For example, the configuration information related to the sidelink symbol includes information related to a position of the sidelink symbol. For example, the position of the sidelink symbol is configured to be the same for the candidate resources.
