摘要： A method of reporting, by a user equipment (UE), channel state information (CSI) in a wireless communication system, includes: receiving, by the UE and from a base station (BS), downlink control information (DCI) related to an aperiodic CSI report that is to be performed by the UE in a slot n; determining, by the UE, a value nCQI_ref based on a number of symbols Z′ related to a time for computing the CSI; determining, by the UE, a CSI reference resource as being a slot n−nCQI_ref in a time domain that is to be used for the aperiodic CSI report; and transmitting, by the UE and to the BS, the aperiodic CSI report in the slot n, based on the CSI reference resource being slot n−nCQI_ref. The CSI may be calculated by using the most recent A CSI-RS, and thereby the most recent CSI may be reported.

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.
