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