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: This specification provides a method for transmitting, by a user equipment (UE), a CSI (Channel State Information) report in a wireless communication system. More specifically, the method includes: receiving, from a base station, downlink control information (DCI) including information for triggering the CSI report; computing CSI based on the number of symbols related to a time for computing the CSI; and transmitting the CSI report to the base station, in which the number of symbols related to the time for computing the CSI is defined based on information for the number of antenna ports, information for a CSI-RS resource, information for a bandwidth granularity, and information for a CSI codebook type.
