Abstract: A method of reporting CSI (channel status information), which is reported to an eNB by a user equipment (UE) in a wireless communication system, is disclosed in the present invention. The method includes the steps of receiving a CSI reporting request signal for a plurality of cells set to the UE from the eNB; generating CSI using a payload arranged in an order of first indicators corresponding a plurality of the cells and second indicators corresponding a part of the plurality of the cells; and reporting the CSI to the eNB in response to the CSI reporting request signal. In this case, the first indicators and the second indicators are arranged to the payload in an ascending order of a corresponding cell ID. If the cell ID is the same, the first indicators and the second indicators are arranged to the payload in an ascending order of a corresponding CSI process index.
