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

A method of transmitting and receiving a signal, by a terminal, in a wireless communication system, the method comprising:

• transmitting, to a base station (BS), performance information regarding whether nonlinear precoding (NLP) or a modulo operation is supported;
• receiving, from the BS, information regarding whether the NLP or the modulo operation is performed in a predetermined resource in a time-frequency resource region determined based on the performance information;
• and
• obtaining one of a control signal, a reference signal (RS), or a data signal transmitted to the terminal by performing the modulo operation on a signal received from the BS according to the received information about whether the NLP or the modulo operation is performed.

A base station (BS) of transmitting and receiving a signal in a wireless communication system, the BS comprising:

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• determine whether each of at least one terminal connected to the BS supports nonlinear precoding (NLP) or a modulo operation,
• determine a plurality of signals that are overlapping-transmitted in a time-frequency resource region from among a control signal, a reference signal (RS), and a data signal transmitted from the BS, based on whether the at least one terminal supports the NLP or the modulo operation, and
• control the transceiver to transmit, to each of the at least one terminal, information about whether the NLP or the modulo operation is performed in a resource where the plurality of signals are transmitted.
