Specifically, a method for transmitting, by a user equipment (UE), Channel State Information (CSI) in a wireless communication system may include: receiving, from a base station, a channel state information reference signal (CSI-RS) through multiple antenna ports; and reporting, to the base station, CSI, in which the CSI may include selection information indicating a plurality of codewords used for generating a precoding matrix in a codebook for reporting the CSI, and a power coefficient, a phase offset, and a phase shift value applied to each of the plurality of codewords in terms of a configured bandwidth, and the precoding matrix may be generated in units of subbands within the configured bandwidth based on a linear combination of the power coefficient, the phase offset, and the phase change value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transmitting and receiving channel state information in wireless communication system and apparatus therefor","description":"Disclosed are a method for transmitting and receiving channel state information in wireless communication system and an apparatus therefor.
