According to an embodiment, an operation method of a terminal in a wireless communication system comprises the steps of: generating a first waveform from a signal related to a physical sidelink control channel (PSCCH) and generating a second waveform from a signal related to a physical sidelink shared channel (PSSCH); generating a third waveform on the basis of a peak to average power ratio (PAPR) and a constellation shift and transmitting the second waveform and the third waveform, wherein the constellation shift is applied only to the first waveform.
