Abstract
Disclosed are a method and device for transmitting and receiving a signal in a wireless communication system. The method may comprise the following steps: transmitting, to a terminal, information of a plurality of demodulation reference signal (DMRS) sequences and information of a plurality of data transformation techniques, transforming a data symbol sequence on the basis of the plurality of data transformation techniques, performing an inverse discrete Fourier transformation (IDFT) on combinations of the plurality of transformed data symbol sequences and the plurality of DMRS sequences, measuring peak-to-average power ratio (PAPR) values with respect to each of the IDFT-performed signals, selecting an IDFT-performed signal having the lowest PAPR value as a result of the measurement, and the selected IDFT-performed signal may be transmitted to a terminal.
