Abstract: Proposed is a method for a first device performing wireless communication. The method may comprise the steps of: determining a first time domain and a second time domain with respect to a physical sidelink feedback channel (PSFCH) resource; performing sidelink data transmission to a second device through a resource on the first time domain; receiving, from the second device, hybrid automatic repeat request (HARQ) feedback associated with the sidelink data transmission; and on the basis of the HARQ feedback, performing sidelink data retransmission to the second device through a resource on the second time domain. For example, the first time domain may precede the PSFCH resource. For example, the second time domain may follow the PSFCH resource.
