Communication Control Device Beam Correlation Prohibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a distributed antenna environment, the overlapping service areas covered by multiple wireless base station devices lead to an increased period required for beam search, making efficient beam selection challenging.
Innovation Solution
A communication control device that estimates the correlation between the ranges of beams emitted by different base station devices and prohibits the use of overlapping beams, thereby reducing the beam search period by preventing simultaneous beam transmission from overlapping base stations.

Engineering Contradiction Analysis
1Measurement precision
If beam selection is performed by time division and brute force in a distributed antenna configuration, then all beams from all distributed antennas can be searched, but the processing period increases significantly
Solution Approach 1:
The communication control device performs preliminary actions by estimating beam range correlations before actual beam selection. It identifies and prohibits correlated beams in advance, eliminating redundant search operations. This preliminary filtering reduces the number of beams that need to be searched while ensuring that the optimal beam is not missed, thus resolving the contradiction between search completeness and processing time.
2Adaptability or versatility
If multiple distributed antennas are arranged to cover overlapping service areas, then communication coverage is improved, but beam search complexity increases
Solution Approach 1:
Before beam selection, the system performs preliminary correlation estimation between beams from different distributed antennas. By identifying and prohibiting correlated beams in advance, the system reduces the search space without compromising coverage. This allows multiple distributed antennas to maintain their coverage advantages while avoiding the exponential increase in search complexity that would otherwise result from searching all beams from all antennas.
