Method and apparatus for transmitting and receiving control and data channels in wireless communication system

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

• transmitting, to a terminal via radio resource control (RRC) signaling, information for a rate matching resource;
• and
• transmitting, to the terminal, downlink control information (DCI) on a physical downlink control channel (PDCCH),
• wherein resources are unavailable for physical downlink shared channel (PDSCH) reception based on the rate matching resource, and
• wherein the PDCCH corresponds to a PDCCH candidate except for at least one PDCCH candidate that overlaps with the resources.

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

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station via radio resource control (RRC) signaling, information for a rate matching resource,
• identify resources that are unavailable for physical downlink shared channel (PDSCH) reception based on the rate matching resource,
• monitor a physical downlink control channel (PDCCH) candidate except for at least one PDCCH candidate that overlaps with the identified resources, and
• receive, from the base station, downlink control information (DCI) based on the monitoring of the PDCCH candidate.
