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).
