Abstract: The present specification relates to a method, performed by a base station, for transmitting and receiving data in a wireless communication system. More particularly, a terminal receives, from the base station, configuration information for setting a control resource set (CORESET) and receives first downlink control information (DCI) and second DCI, on the basis of the configuration information. Afterward, the terminal receives a first physical downlink shared channel (PDSCH) on a resource scheduled by the first DCI and receives a second PDSCH on a resource scheduled by the second DCI. Afterward, the terminal transmits first Ack/Nack with respect to the first PDSCH and Ack/Nack with respect to the second PDSCH, wherein the first Ack/Nack and the second Ack/Nack are transmitted through different resources in the same slot.
