Method of transmitting and receiving data in wireless communication system supporting full-duplex radio and apparatus therefor

A user equipment (UE) for transmitting and receiving a signal in a wireless communication system, the UE comprising:

• a transmitter;
• a receiver;
• and
• a controller,
• wherein the receiver is configured to receive downlink control information (DCI) including frequency allocation information from a base station (BS), the controller is configured to identify frequency bands allocated as an uplink (UL) band and a downlink (DL) band based on the frequency allocation information, and the transmitter is configured to transmit a UL signal based on the DCI,
• wherein the transmitter includes an out-of-band emission reduction (OOBER) device, and
• wherein the OOBER device is enabled based on whether the allocated frequency bands correspond to edges of a bandwidth part (BWP).

A method of transmitting and receiving a signal by a base station (BS) in a wireless communication system, the method comprising:

• transmitting downlink control information (DCI) including frequency allocation information to a user equipment (UE);
• and
• receiving an uplink (UL) signal from the UE based on the DCI,
• wherein the frequency allocation information includes information about frequency bands allocated as a UL band and a downlink (DL) band,
• wherein a transmitter of the UE includes an out-of-band emission reduction (OOBER) device, and
• wherein the OOBER device is enabled based on whether the allocated frequency bands correspond to edges of a bandwidth part (BWP).

A base station (BS) for transmitting and receiving a signal in a wireless communication system, the BS comprising:

• a transmitter;
• a receiver;
• and
• a controller,
• wherein the transmitter is configured to transmit downlink control information (DCI) including frequency allocation information to a user equipment (UE), and the receiver is configured to receive an uplink (UL) signal from the UE based on the DCI,
• wherein the frequency allocation information includes information about frequency bands allocated as a UL band and a downlink (DL) band,
• wherein the UE includes an out-of-band emission reduction (OOBER) device, and
• wherein the OOBER device is enabled based on whether the allocated frequency bands correspond to edges of a bandwidth part (BWP).

An apparatus for a user equipment (UE), comprising:

• at least one processor;
• and
• at least one computer memory operatively coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations,
• wherein the operations comprise:
• 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 through a transmitter of the UE,
• wherein the transmitter of the UE includes an out-of-band emission reduction (OOBER) device, and
• wherein the OOBER device is enabled based on whether the allocated frequency bands correspond to edges of a bandwidth part (BWP).

A computer-readable storage medium storing at least one computer program including instructions which when executed by at least one processor, cause the at least one processor to perform operations for a user equipment (UE),

• wherein the operations include:
• 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 through a transmitter of the UE,
• wherein the transmitter of the UE includes an out-of-band emission reduction (OOBER) device, and
• wherein the OOBER device is enabled based on whether the allocated frequency bands correspond to edges of a bandwidth part (BWP).
