Disclosed is a method by which a terminal transmits a signal in a wireless communication system. The terminal can receive configuration information for setting a first subcarrier spacing (SCS) for a plurality of slots, and transmit a physical sidelink shared channel (PSSCH) in the plurality of slots. At this time, if the terminal coexists with a legacy terminal in a co-channel and the plurality of slots fully overlap a legacy subframe of the legacy terminal, second transmission power in at least one slot that excludes a first slot from among the plurality of slots can be limited by means of first transmission power of the first slot.
