Abstract:
A method of reporting channel state information (CSI) at a machine type communication (MTC) user equipment (UE) in a wireless communication system, includes selecting a set of M downlink subframes as a CSI reference resource and a subband among a set of N subbands; measuring a wideband channel quality indicator (CQI) for the set of N subbands and a subband CQI for the subband through the CSI reference resource; and transmitting, to a base station, the wideband CQI and the subband CQI through an uplink subframe, wherein the MTC UE measures the wideband CQI and the subband CQI based on a cell-specific reference signal (CRS) received through the M downlink subframes which are located before the uplink subframe, and wherein the set of N subbands is configured to perform frequency hopping.
