Abstract: The present specification relates to a method for transmitting and receiving data by a base station in a wireless communication system. More specifically, a terminal receives configuration information for configuration of a control resource set (CORESET) from the base station. Thereafter, the terminal receives first downlink control information (DCI) and second DCI for generation of ACK/NACK by using a semi-static method on the basis of the configuration information. The terminal receives a first physical downlink shared channel (PDSCH) and a second PDSCH, and transmits first Ack/Nack for the first PDSCH and Ack/Nack for the second PDSCH, on a resource scheduled by the first DCI.
