摘要： 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.

摘要： A method of performing wireless communication by a first device is proposed. The method includes receiving downlink control information (DCI) related to first sidelink from a base station, and transmitting, to the base station, a confirmation message for reception of the DCI related to the first sidelink through a first medium access control (MAC) control element (CE). For example, the first MAC CE may include at least one index information related to at least one semi-persistent scheduling (SPS) configuration activated or released by the DCI.
