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).

Abstract: The present document discloses a method for transmitting or receiving a signal by a terminal in a wireless communication system, the method comprising the steps of: receiving information relating to a timing advance (TA) and an uplink (UL) grant from a base station; transmitting a radio resource control (RRC) message to the base station on the basis of the TA and UL grant; and receiving downlink control information (DCI) on the basis of the RRC message, wherein the RRC message comprises information indicating whether the terminal supports a full-duplex radio (FDR) mode, and the DCI comprises an additional field indicating whether the FDR mode is allowed for the terminal.

Abstract: The present document discloses a method by which a terminal transmits/receives a signal in a wireless communication system, comprising the steps of: receiving frequency configuration information from a base station; receiving a control channel including downlink control information (DCI) from the base station; receiving a downlink signal from the base station on the basis of the DCI; and transmitting a hybrid automatic repeat and request acknowledgement/negative-acknowledgement (HARQ-ACK/NACK) in response to the downlink signal received from the base station, wherein the frequency configuration information includes information about length L of a predetermined frequency resource from the lowest frequency at which the downlink signal is received and information about length R of a predetermined frequency resource from the highest frequency at which the downlink signal is received, and the DCI includes indices indicating lengths L and R.
