Abstract: In one embodiment, a method by which a first device performs wireless communication is proposed. The method may comprise the steps of: determining at least one first candidate slot for selecting a first sidelink (SL) resource; performing sensing of at least one first slot related to the at least one first candidate slot; and selecting the first SL resource in the at least one first candidate slot on the basis of the sensing. For example, a first channel busy ratio (CBR) related to the at least one first slot may be measured on the basis of the number of the at least one first slot that is greater than or equal to a first threshold value.
