A disclosure of the present specification provides a method for switching a bandwidth part (BWP) for sidelink communication. The method may comprise the steps of: receiving information on BWP switching timing from a base station; and performing BWP switching on the basis of the information on BWP switching timing. The information on BWP switching timing may include first BWP switching information or second BWP switching information. The first BWP switching information may be time information about BWP switching from a sidelink (SL) to an uplink (UL) or a downlink (DL) with the base station. The second BWP switching information may be time information about BWP switching to the sidelink (SL) from the uplink (UL) or the downlink (DL) with the base station.
