5G Network Node Carrier Adaptation for Atmospheric BS-to-BS Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G wireless communication networks face challenges in effectively managing BS-to-BS interference due to atmospheric conditions, which can cause radio signaling to travel long distances and interfere with other network nodes, especially in large-scale networks where physical cell IDs are limited and reused, leading to ambiguous identification of interference sources.
Innovation Solution
The implementation of a method that adapts the utilization of secondary carriers in network nodes based on received indications of BS-to-BS interference, allowing for preemptive action to limit interference, using processing and radio circuitry to manage carrier usage and timing, and employing reference signaling to identify interfering nodes and groups, thereby enhancing interference handling in 5G networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical cell IDs are reused in large-scale networks, then network scalability is improved, but interference source identification becomes ambiguous
Solution Approach 1:
The patent introduces atmospheric channel characteristics as an intermediary factor to distinguish between different network nodes. By measuring and analyzing the atmospheric channel properties (such as signal propagation characteristics, fading patterns, and spatial distribution), the system can identify interfering nodes even when their physical cell IDs are reused, thus resolving the ambiguity in interference source identification while maintaining network scalability.
2Reliability
If atmospheric channel effects are considered, then interference handling accuracy is improved, but system complexity increases
Solution Approach 1:
The patent performs preliminary measurement and characterization of atmospheric channel effects during network setup or periodic updates. By pre-characterizing the atmospheric channel properties and storing them in databases, the system can quickly retrieve and apply relevant information during interference handling without performing complex real-time analysis, thus improving accuracy while limiting complexity increase.
Solution Approach 2:
The system implements feedback mechanisms where network nodes continuously monitor and report atmospheric channel conditions and interference characteristics. This feedback information is used to update interference models and adjust handling strategies dynamically, improving accuracy through adaptive response while managing complexity through automated learning and optimization processes.
3Reliability
If preemptive interference action is taken, then interference reduction effectiveness is improved, but response time requirements increase
Solution Approach 1:
The patent implements preemptive interference action by continuously monitoring atmospheric channel characteristics and detecting potential interference scenarios before they fully develop. The system uses predictive models based on historical data and real-time measurements to anticipate interference events, allowing network nodes to take preventive actions (such as adjusting transmission parameters or switching carriers) before significant interference occurs, thus improving effectiveness while managing response time through proactive rather than reactive handling.
