Method and apparatus for transmitting/receiving control information in wireless communication system

A method of a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, control channel configuration information through radio resource control (RRC) signaling;
• receiving, from the terminal, in case that it is determined to use a partial resource as a downlink within a channel occupancy interval acquired by the terminal, uplink control information, the uplink control information including at least one configuration information among the control channel configuration information;
• and
• transmitting, to the terminal, a control channel signal based on the configuration information.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• receive, via the transceiver from a base station, control channel configuration information through radio resource control (RRC) signaling,
• transmit, via the transceiver to the base station, in case that it is determined to use a partial resource as a downlink within a channel occupancy interval acquired by the terminal, uplink control information, the uplink control information including at least one configuration information among the control channel configuration information, and
• receive, via the transceiver from the base station, a control channel signal based on the configuration information.
