Here, the method comprises the steps of: receiving a pilot signal from a base station; and feeding back first CSI information for a horizontal direction domain and second CSI information for a vertical direction domain on the basis of the 3D beamforming. Here, when a precoding indicator is a first value, first wideband (WB) CSI information and second wideband (WB) CSI information may be fed back, and when the precoding indicator is a second value, first subband (SB) CSI information and second subband (SB) CSI information may be fed back."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for feeding back CSI information in wireless communication system, and apparatus therefor","description":"The present application provides a method for feeding back, by a terminal, CSI information in a wireless communication system to which 3D beamforming is applied.
