    Abstract: The present specification proposes a method of reporting channel quality information (CQI) by a user equipment (UE) to a base station (BS) in a wireless communication system. Specifically, the method includes the step of receiving a cell specific reference signal from the BS; calculating the CQI using the cell specific reference signal on the assumption that a specific number of resource elements (REs) for a demodulation-reference signal (DM-RS) exists; and reporting the CQI to the BS. Especially, if a most recent reported rank is 3 or 4, the specific number of REs for the DM-RS is assumed as a specific value, which is different from a minimum number of REs for the DM-RS or a maximum number of REs for the DM-RS.
