Resource configuration method and apparatus for transmission or reception of uplink or downlink in wireless communication system

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• receive configuration information for a guard band;
• determine whether the guard band is activated based on the configuration information;
• and
• when the guard band is activated, determine whether to transmit an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain.

An operating method of a base station (BS) in a wireless communication system, the operating method comprising:

• transmitting configuration information for a guard band to a user equipment (UE);
• and
• when the guard band is activated, receiving an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain,
• wherein whether the guard band is activated is determined by the UE based on the configuration information.
