Abstract: Provided is a method performed by a user equipment (UE) in a wireless communication system. The method includes performing communication with a base station based on a full-duplex mode, transmitting, to the base station, a first message for requesting a duration for calibration of a circuit for analog self-interference cancellation (SIC), receiving, from the base station, a second message for allocating the duration, and performing the calibration of the circuit during the duration. Herein, during the duration, the UE is controlled to operate based on a half-duplex mode.

Abstract: The present document relates to a method for transmitting and receiving a signal by a user equipment in a wireless communication system, and discloses the method for transmitting and receiving a signal, comprising the steps of: receiving a first reference signal from a base station; receiving a second reference signal from the base station; measuring power of each of the received first reference signal and the received second reference signal; and comparing the sizes of the measured power of the first reference signal and the measured power of the second reference signal, wherein the first reference signal is received in a half-duplex (HD) transmission mode, the second reference signal is received in a full-duplex (FD) transmission mode, and an FD gain value of the FD transmission mode is changed on the basis of a result of the comparing.

Abstract: A method of transmitting and receiving a signal at a terminal in a wireless communication system may be provided. A method of, at a terminal, transmitting and receiving a signal may comprise generating a first signal at transmitting end of the terminal and transmitting the generated first signal through an antenna and receiving a second signal through the antenna and transferring the second signal to a receiving end of the terminal. A differential circulator may be provided between the transmitting end and receiving end and the antenna, and the first signal may be transmitted and the second signal may be received at the same time based on the differential circulator.

Abstract: A method of transmitting and receiving a signal by a user equipment (UE) in a wireless communication system is disclosed. The method includes receiving downlink control information (DCI) including frequency allocation information from a base station (BS), identifying frequency bands allocated as an uplink (UL) band and a downlink (DL) band based on the frequency allocation information, and transmitting a UL signal through a transmitter of the UE based on the DCI. The transmitter of the UE includes an out-of-band emission reduction (OOBER) device, and the OOBER device is enabled based on whether the allocated frequency bands correspond to edges of a bandwidth part (BWP).
