Abstract: The present disclosure provides a method for reporting CSI in a wireless communication system. In the present disclosure, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: receiving, from an eNB, downlink control information (DCI) indicating activation of semi-persistent (SP) CSI reporting, in which the downlink control information is scrambled with a specific RNTI distinguished from a Cell-Radio Network Temporary Identity (C-RNTI); and reporting, to the eNB, the semi-persistent CSI through a physical uplink shared channel (PUSCH) based on the received downlink control information.

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.

Abstract: A method for reporting channel state information (CSI) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving configuration information related to channel state information (CSI): receiving a downlink reference signal (DL RS); calculating the CSI on the basis of the DL RS; and reporting the CSI. The CSI relates to group-based beam reporting, and a specific reference for the CSI reporting may be set for each group on the basis of the configuration information. The CSI includes information on one or more of DL RSs on the basis of the specific reference for each group.
