Abstract
The present specification provides a method for transmitting a signal in a wireless communication system. More specifically, the method performed by a transmission terminal comprises the steps of: generating at least one bit into a complex symbol by using a modulation scheme; mapping the complex symbol to subcarriers each having an even index or subcarriers each having an odd index among subcarriers of at least one configured resource block; performing IFFT on the subcarriers to which the complex symbol is mapped, in order to generate a time-continuous signal; performing a DC bias on the time-continuous signal; and transmitting the DC biased signal.

A method of transmitting a signal in a wireless communication system, the method performed by a transmission stage comprising:
- generating at least one bit as a complex value symbol by using a modulation scheme;
- mapping the complex value symbol to subcarriers having an even index or subcarriers having an odd index among subcarriers of at least one configured resource block (RB);
- performing an inverse fast Fourier transform (IFFT) on the subcarriers to which the complex value symbol has been mapped in order to generate a time continuous signal;
- performing a direct current (DC) bias on the time continuous signal;
- and
- transmitting the DC-biased signal.
A method of receiving a signal in a wireless communication system, the method performed by a reception stage comprising:
- separating the signal into a real part signal and an imaginary part signal;
- generating a complex value signal through repetition or symbol inversion for each of the real part signal and the imaginary part signal;
- and
- performing a fast Fourier transform (FFT) on the complex value signal in order to detect a modulation symbol corresponding to at least one bit.
A transmission stage for transmitting a signal in a wireless communication system, comprising:
- a radio frequency (RF) module for transmitting and receiving radio signals;
- and
- a processor configured to control the RF module, wherein the processor is configured to:
- generate at least one bit as a complex value symbol by using a modulation scheme;
- map the complex value symbol to subcarriers having an even index or subcarriers having an odd index among subcarriers of at least one configured resource block (RB);
- perform an inverse fast Fourier transform (IFFT) on the subcarriers to which the complex value symbol has been mapped in order to generate a time continuous signal;
- perform a direct current (DC) bias on the time continuous signal;
- and
- transmit the DC-biased signal.
