Abstract
A method for constructing a codebook in a multiple-antenna wireless communication system and an apparatus therefor are disclosed. Specifically, constructing a codebook in a multiple-antenna wireless communication system comprises the steps of: receiving parameters for constructing a codebook from a base station; and constructing a codebook using the parameters for constructing the codebook, wherein the parameters for constructing the codebook may include a phase value (α) of a first code vector forming the codebook, a phase difference (β) between code vectors that are adjacent to one another within the codebook, and the number of bits (γ) that is required when feeding back a code vector selected thin the codebook.
