Method and apparatus for configuration of repetitive transmission and reception of downlink control information in wireless communication system

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

• a transceiver;
• and
• a controller configured to:
• receive, via the transceiver, configuration information indicating that a first search space and a second search space are linked for physical downlink control channel (PDCCH) repetitions, and
• for the first search space and the second search space, and for a third search space that is not linked with the first search space or the second search space:
• monitor a first PDCCH candidate associated with the first search space and a second PDCCH candidate associated with the second search space for detection of a first downlink control information (DCI) format, and
• monitor a third PDCCH candidate for detection of a second DCI format having a same size as the first DCI format,
• wherein either the first PDCCH candidate or the second PDCCH candidate, and the third PDCCH candidate have an identical scrambling and use a same control channel element (CCE) in a control resource set (CORESET), and
• wherein the third PDCCH candidate is not counted for monitoring.
