    Abstract: Provided is a method for a user device in a wireless communication system according to an aspect of the present disclosure in which: allocation information relating to a plurality of bandwidth parts (BWPs) is received, wherein the plurality of BWPs comprise a first BWP and a plurality of second BWPs comprised in the first BWP; a sidelink signal is transmitted on the first BWP on the basis of the activation of the first BWP; and the sidelink signal is transmitted on at least one second BWP on the basis of the activation of the at least one second BWP among the plurality of second BWPs. The allocation information comprises: the start point of the first BWP and the plurality of second BWPs; the size of the first BWP and the plurality of second BWPs; and the gap among the plurality of second BWPs. Each of the plurality of second BWPs is allocated within the first BWP from the start point in the gap unit on a frequency domain.
