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: 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).
