Abstract: Provided are a method and device for processing Channel State Information (CSI), User Equipment (UE) and an Evolved Node B (eNodeB). The method includes: storing one or more sets of precoding codebook models the same as those of an eNodeB; determining a precoding codebook model for feeding back CSI; and sending the CSI to the eNodeB by adopting the determined precoding codebook model. By the solution, the problems of difficulty in code word selection and increase of link overhead during application of a codebook-based CSI feedback manner to massive Multi-input Multi-output (MIMO) in the related technology is solved, and the effect of reducing codebook transmission overhead is further achieved.
