Terminal Interference Control in Unlicensed Band Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems like 5G, interference between networks operated by different business operators can lead to deterioration in communication quality due to the lack of coordination and mutual interference between unlinked networks.
Innovation Solution
A user terminal that receives information related to resource measurement from multiple networks and controls the reporting of measurement results to suppress interference, allowing for autonomous or coordinated interference control between networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple networks of different business operators operate in the same frequency domain without coordination, then network deployment flexibility and market competitiveness are improved, but mutual interference occurs and communication quality deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where terminals report measurement results (including interference information) to networks, and networks adjust transmission parameters based on this feedback. This allows uncoordinated networks to automatically adapt to each other's presence and reduce mutual interference while maintaining deployment flexibility
Solution Approach 2:
The system enables self-service interference management where terminals autonomously perform measurements and networks autonomously adjust parameters based on reported information. This eliminates the need for direct coordination between networks while still achieving interference reduction through individual network optimization
2Ease of manufacture
If transmission and reception points are arranged without mutual coordination between networks, then deployment simplicity and cost are reduced, but interference between networks increases
Solution Approach 1:
Measurement results and interference information are fed back from terminals to networks, enabling networks to adjust transmission parameters and reduce interference automatically, eliminating the need for complex coordination during deployment
Solution Approach 2:
The system performs preliminary measurements and reports interference information before actual communication begins, allowing networks to pre-adjust transmission parameters to avoid interference while maintaining simple deployment
