Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The expansion of network capacity in mobile communications systems using multi-beam antennas is hindered by antenna azimuth, base station planning, and user distribution in split multi-cell environments, leading to a loss of split gains and reduced network capacity expansion effectiveness.
Innovation Solution
A beam selection method that measures sounding reference signals (SRS) from terminals to determine spectral efficiencies, calculates the spectral efficiency of each beam group, and identifies a target beam group with optimal coverage, thereby mitigating inter-cell interference and improving network capacity expansion and overall coverage.

Engineering Contradiction Analysis
1Productivity
If multi-beam antenna is used to expand network capacity by increasing the quantity of tunnels, then spectrum efficiency is improved, but split gains are lost due to antenna azimuth and user distribution issues
Solution Approach 1:
The patent changes the parameter of beam selection from random or fixed selection to selection based on spectral efficiency calculations. By computing spectral efficiency for different beam groups and selecting the optimal one, the system adapts to actual channel conditions and user distribution, thereby recovering split gains while maintaining network capacity expansion.
2Productivity
If multi-beam antenna is used to increase partitions of service information channel, then spectrum efficiency is improved, but overall coverage effect is reduced due to inter-cell interference
Solution Approach 1:
The patent applies local quality by evaluating spectral efficiency for each beam group locally based on actual channel conditions and user distribution. Instead of uniformly applying beam configurations across all cells, the system determines optimal beam groups for each cell based on local spectral efficiency measurements, thereby reducing inter-cell interference while maintaining high spectrum efficiency.
