Uplink resource configuration method and apparatus in wireless communication system

A method for receiving uplink control information in a wireless communication system, the method comprising:

• transmitting configuration information on a plurality of bandwidth parts (BWPs) to a terminal;
• transmitting downlink control information and downlink data to the terminal;
• transmitting BWP adaptation information which indicates a change of an active BWP to the terminal;
• identifying an uplink control channel resource for receiving acknowledgement information in response to the downlink data;
• and
• receiving the acknowledgement information on the identified uplink control channel resource from the terminal.

A terminal for transmitting uplink control information in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive configuration information on a plurality of bandwidth parts (BWPs) from a base station,
• receive downlink control information and downlink data from the base station,
• receive BWP adaptation information which indicates a change of an active BWP from the base station,
• identify an uplink control channel resource for transmitting acknowledgement information in response to the downlink data, and
• transmit the acknowledgement information on the identified uplink control channel resource to the base station.
