It relates to a method and apparatus for a terminal to report channel state information (CSI) in a wireless communication system. According to the present invention, the terminal can receive configuration information related to CSI from the base station, and measure CSI based on the configuration information. Then, the terminal includes the step of reporting the measured CSI to the base station, the CSI is composed of a first part and a second part, the first part is a rank indicator (Rank Indicator: RI), channel quality indicator It includes a channel quality indicator (CQI) and an indicator indicating the number of non-zero amplitude coefficients, and the second part can provide a method and apparatus including a precoding matrix indicator (PMI). |
