Based on various embodiments of the present disclosure, a method for configuring a UCI for SL transmission to be reported by a UE to a base station and an apparatus supporting the same are proposed. In addition, a method for a specific UE that transmits the corresponding UCI and a subsequent procedure corresponding thereto are proposed. In addition, a method for selecting, by a specific UE, a time when the specific UE transmits the UCI for SL transmission to a base station, and a transmission container (e.g., PUCCH or PUSCH), and an apparatus supporting the same are proposed.
