    Abstract: Provided is a method for a first device to perform wireless communication. The method may include the steps of: receiving a configured grant from a base station; transmitting a first transport block through a first sidelink resource related to a first hybrid automatic repeat request (HARQ) process ID and allocated by the configured grant; failing to transmit the first transport block; and transmitting a second transport block through a second sidelink resource related to a second HARQ process ID and allocated by the configured grant, on the basis of the second HARQ process ID related to the second sidelink resource being the same as the first HARQ process ID.

    Abstract: Provided are a method for a first device to perform wireless communication, and a device for supporting same. The method may comprise the steps of: selecting a first sidelink (SL) transmission resource within a selection window on the basis of sensing in a first time interval; selecting a second SL transmission resource on the basis of sensing in a second time interval; and performing SL transmission by using the second SL transmission resource. Here, the second time interval may be a time interval prior to the first SL transmission resource.

    Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: obtaining a sidelink (SL) discontinuous reception (DRX) configuration including information related to a timer for an active time and information related to a hybrid automatic repeat request (HARQ) round trip time (RTT) timer; starting the timer for the active time; receiving, from a second device through a physical sidelink control channel (PSCCH) based on a first SL resource, a first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) and a second SCI; and receiving, from the second device through the PSSCH based on the first SL resource, the second SCI and data. Herein, based on resource allocation information for a second SL resource being included in the first SCI, the first device may not monitor retransmission of the data from the second device in a time domain between the first SL resource and the second SL resource, and based on the resource allocation information for the second SL resource not being included in the first SCI, the HARQ RTT timer included in the SL DRX configuration may be started by the first device.
