Specifically, a terminal monitors at least one first candidate PDCCH in a first search space and at least one second candidate PDCCH in a second search space, wherein the first search space and the second search space may partially or entirely overlap each other on a time axis. Thereafter, the terminal may search for a first DCI in the at least one first candidate PDCCH and a second DCI in the at least one second candidate PDCCH, wherein the sum of the number of the at least one first candidate PDCCH and the number of the at least one second candidate PDCCH may be less than or equal to a specific number.
