Abstract: The present specification relates to a wireless communication system and, more particularly, to a method for reporting a channel state and an apparatus therefor. When a plurality of channel state information-reference signal (CSI-RS) resources are set for a channel state information (CSI) process, a terminal of the present invention generates channel state information indicating a CSI-RS resource indicator (CRI) indicating one of the plurality of CSI-RS resources and a rank indicator (RI) which is based on the CRI. The terminal reports the channel state information. Accordingly, the present invention is capable of more efficient channel state reporting by transmitting a CRI indicating a CSI-RS resource, selected from among a plurality of CSI-RS resources set for the CSI process, together with the RI for the selected CSI-RS resource.
