Abstract: A method for a machine type communication (MTC) terminal to report a channel state information (CSI) in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: selecting a set of M downlink subframes as a CSI reference resource for the MTC terminal; measuring a channel quality indicator (CQI) through the CSI reference resource; and transmitting a CSI report including the CQI to a base station through an uplink subframe, wherein the MTC terminal is configured to repeatedly receive an MTC signal by frequency-hopping N sub-bands among a plurality of sub-bands. The number ‘M’ of the downlink subframes to be included in the CSI reference resource is determined on the basis of an upper layer parameter received from the base station. Further, the MTC terminal may measure the CQI on the basis of a cell-specific reference signal (CRS) received through the M downlink subframes selected from a reference downlink subframe located before the uplink subframe.
