AI Technical Summary

Technical Problem

In cellular and satellite communication systems, the use of massive MIMO antennas has led to a continuous narrowing of beamwidth, resulting in some public or service signals failing to meet beam coverage requirements. Existing technologies achieve beamwidth by sacrificing antenna power, which affects signal transmission.

Method used

By redetermining the number and layout of antenna elements in the antenna system, a target beam combination is constructed, including N horizontal target beams and M vertical target beams. The beam broadening is achieved by utilizing the phase difference relationship, ensuring that the peak angle of each beam is within a preset range and avoiding sacrificing antenna power.

Benefits of technology

Without reducing antenna power, the beamwidth is increased to meet beam coverage requirements and improve signal transmission performance.

Abstract

The invention provides a beam broadening method, device and equipment, and relates to the technical field of computers, and the method comprises the steps: obtaining a preset beam angle coverage range of an antenna system, the antenna system comprises N * M antenna units, determining a target beam combination according to M and N, the target wave beam combination comprises N target wave beams in the horizontal direction and M target wave beams in the vertical direction, the phase difference of the horizontal target wave beams is in positive correlation with the first serial number, the phase difference of the vertical target wave beams is in positive correlation with the second serial number, and the peak angle of each target wave beam is within the wave beam angle coverage range; the difference value between the first peak angle and the first angle is smaller than a first threshold value, the difference value between the second peak angle and the second angle is smaller than a second threshold value, and beam broadening is performed on the antenna system according to the target beam combination, so that beam broadening of the antenna system can be realized without sacrificing the antenna power.
