Base Station Deployment Filtering for Satellite Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G network, base stations sharing the same frequency band with satellite communication systems face co-channel interference issues, leading to unavailable satellite communication due to radio interference, especially when deploying a large number of base stations.
Innovation Solution
A communication control apparatus that acquires deployment information for base stations and location information for stationary communication stations sharing the same frequency band, calculates interference values, and selects base stations with interference values below a predetermined threshold for deployment, thereby minimizing co-channel interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base stations are deployed based on network design to provide broad coverage and connectivity, then coverage area and user connectivity are improved, but co-channel interference with satellite communication systems increases
Solution Approach 1:
The patent calculates interference values for all candidate base stations before deployment and selects only those that meet the interference threshold requirement. This preliminary screening prevents high-interference base stations from being deployed, thereby avoiding future interference issues while still achieving adequate coverage through the selection of suitable locations.
Solution Approach 2:
The patent introduces an interference threshold parameter to filter base station deployment locations. By changing the selection criterion from purely coverage-based to coverage-plus-interference-based, the system achieves both adequate coverage and acceptable interference levels with satellite communications.
2Object-affected harmful factors
If radio resources are allocated to avoid interference between base stations and other communication systems, then interference is reduced, but resource allocation complexity increases
Solution Approach 1:
The patent performs interference assessment and base station selection before deployment, rather than managing dynamic resource allocation after deployment. This preliminary action simplifies the system by avoiding complex ongoing resource coordination mechanisms.
Solution Approach 2:
The patent extracts the interference management problem from the operational phase and moves it to the planning phase. By determining suitable base station locations in advance based on interference calculations, the need for complex real-time resource allocation to manage interference is eliminated.
3Quantity of substance
If a large number of base stations are deployed to enhance network capacity, then network capacity and connectivity are improved, but managing interference becomes more difficult
Solution Approach 1:
The patent calculates and compares interference values for all candidate base stations before deployment, selecting only those that meet the interference threshold. This preliminary filtering enables the deployment of multiple base stations while maintaining manageable interference levels through pre-screening.
Solution Approach 2:
The patent applies an interference threshold parameter to filter the set of deployable base stations. This parameter-based filtering allows multiple base stations to be deployed while automatically excluding those that would create excessive interference, thus managing complexity through quantitative criteria.
