Abstract: Disclosed herein is a method for reporting channel state information (CSI) of a terminal in a wireless communication system. The method includes: measuring a CSI-RS (reference signal) transmitted from a base station through multiple panels; and reporting CSI generated based on the CSI-RS measurement to the base station, wherein, when the terminal reports a WB (Wideband) panel corrector and SB (Subband) panel corrector for the multiple panels as the CSI, the WB panel corrector and the SB panel corrector are reported with different bit widths.

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.
