1. A method for a terminal to perform wireless communication in a wireless communication system, the method comprising:
receiving configuration information related to a plurality of control resource sets (CORESETs);
receiving configuration information related to a plurality of search spaces, each corresponding to each of the plurality of CORESETs,
wherein the configuration information related to the plurality of search spaces includes linking information indicating that a first search space among the plurality of search spaces and a second search space among the plurality of search spaces are linked;
receiving first downlink control information (DCI) included in a first physical downlink control channel (PDCCH) on the first search space;
receiving second DCI included in a second PDCCH on the second search space,
wherein the first DCI and the second DCI are identical to each other,
transmitting a physical uplink control channel (PUCCH) carrying hybrid automatic repeat request (HARD)-acknowledgement (ACK) information on a resource,
wherein the resource is determined based on a PDCCH on a search space having a lower search space index among the first search space and the second search space, among the first PDCCH and the second PDCCH.
