Abstract

A method to generate a beamforming vector by a terminal includes receiving information on a first precoding matrix and a second precoding matrix from a serving base station; and generating a beamforming vector by linearly combining the first precoding matrix and the second precoding matrix.

Description

technical field [0001] The invention relates to a method for generating beamforming vectors. Background technique [0002] A multiple-input multiple-output (MIMO) communication system that is an antenna system that can perform multiple input and output is a communication system that can transmit data to several routes by increasing the antennas of the base station and the terminal to two or more and for each route A technology that detects signals received from the receiving end to reduce interference and reduce each transmission speed. [0003] A terminal using multiple antennas can use beamforming vectors to control the transmission direction of data. However, since beamforming vectors may cause interference between adjacent cells, there is a need for a method of generating beamforming vectors in consideration of interference between adjacent cells. [0004] The above information disclosed in this Background section is only for enhancement of understanding of the backgro...
