Abstract

PROBLEM TO BE SOLVED: To provide a method of generating a codebook and a method and device for data transmission.

SOLUTION: A method for data transmission includes the steps of: receiving a label of a code word in an eight-antenna codebook; transmitting the label by user equipment; retrieving a code word identified with the label from the eight-antenna codebook; coding transmission data using the code word; including code words of eight antennas whose ranks are at least eight in the eight-antenna code book; obtaining the code words of the eight antennas whose ranks are 8 by multiplying an inverse matrix of a rotation matrix of the eight antennas by an eight-dimensional matrix formed of code words of four antennas whose ranks are four or obtaining the code words of the eight antennas whose ranks are eight by code words of eight antennas whose ranks are four; and obtaining the code words of the eight antennas whose ranks are four according to the code words of the four antennas.
