Abstract
(EN)

The present invention relates to a method for reporting a channel state in a wireless communication system according to one embodiment of the present invention, wherein a terminal can retune between a plurality of narrowbands and receive data, and the method may comprise the steps of: receiving a configuration for reporting a channel state; calculating a channel quality indicator for all the plurality of narrowbands if a periodical broadband feedback mode is configured according to the configuration for reporting a channel state; and reporting the calculated channel quality indicator.
