Abstract: 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.

A method by which a terminal performs uplink transmission in a wireless communication system according to one embodiment of the present disclosure comprises the steps of: receiving, from a base station, first configuration information related to mapping between one or more uplink reference signals (UL RS) and one or more downlink (DL) RS; receiving, from the base station, second configuration information related to a plurality of spatial parameter candidates for uplink transmission; and performing uplink transmission in N (N ≥ 1) transmission opportunities (TO) on the basis of at least one among N uplink default spatial parameters and N pathloss reference signals (PL RS). The N uplink default spatial parameters are respectively associated with the N TOs. The N PL RSs are respectively associated with the N TOs. The default uplink spatial parameter for a specific TO among the N TOs may be: one spatial parameter, specified by a predefined rule, among the plurality of spatial parameter candidates based on the second configuration information; or a UL RS mapped to the one spatial parameter on the basis of the first configuration information.
