Problems solved by technology

[0016] However, in the above method, it is necessary to utilize the data received from the entire beam used in each stage, and estimate the angle of the terminal (ie, the angle of arrival of the signal from the terminal) by performing matrix calculation on the data, which requires a relatively large amount of calculation

Abstract

A beamforming device is provided. The beamforming apparatus includes: a beam derivation unit for deriving, from a plurality of reception beams, a first reception beam for receiving a maximum reception signal from a terminal and a second reception beam for receiving a second maximum reception signal from the terminal and a control unit for estimating the direction of the terminal based on a ratio between a magnitude of a reception signal received through the first reception beam and a magnitude of a reception signal received through the second reception beam.

Description

technical field [0001] The present invention relates to a beamforming device and a beamforming method, and more particularly, to a beamforming device and a beamforming method in a higher frequency band-based wireless communication system using a plurality of antenna beams. Background technique [0002] The lower frequency band below 6 GHz, which is mainly used in current mobile communications, is completely used or divided by existing systems such as mobile communications, broadcasting, and satellite communications, making it difficult to secure ultra-wide bandwidth frequencies for large-capacity data transmission. [0003] As a result, centimeter waves such as 6 GHz or higher (electromagnetic waves having wavelengths in centimeters corresponding to the frequency range of 3 to 30 GHz) or millimeter waves (having wavelengths in millimeters corresponding to the frequency range of Electromagnetic waves) Such higher frequency bands become the key spectrum of the fifth generation...
