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.

Method and device for transmitting and receiving signal in wireless communication system

The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method of transmitting or receiving a signal by a user equipment (UE) in a mobile communication system is provided. The method may include: identifying a neural network model for transmitting first information to a base station (BS); learning a connection weight of the neural network model using the first information; transmitting, to the base station, second information for updating a weight of a second partial neural network corresponding to the base station based on a result of the learning; and updating a weight of a first partial neural network corresponding to the UE based on the result of the learning.
