Dual Connectivity Interference Mitigation via Dynamic Frequency Reassignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network technologies fail to detect and mitigate interference between wireless signals from different frequency bands in dual connectivity networks, leading to throughput degradation and communication inhibition.
Innovation Solution
A system and method that detect interfering wireless signals and provide instructions to base stations to reassign signals from one frequency band to another, ensuring that signals above a certain power threshold are moved to non-interfering bands, thereby reducing inter-technology/inter-band interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless signals are assigned to different frequency bands in dual connectivity networks, then network capacity and connectivity are improved, but inter-band interference occurs between signals from different mobile networks
Solution Approach 1:
The patent implements a feedback mechanism where the network entity receives interference indicators from user equipment or base stations, automatically detects inter-band interference conditions, and triggers reassignment of wireless signals to different frequency bands. This closed-loop feedback system enables dynamic adaptation to interference conditions while maintaining network connectivity.
Solution Approach 2:
The patent changes the frequency band parameter of wireless signals dynamically based on detected interference conditions. When interference is detected between signals on different frequency bands, the system reassigns one or more signals to alternative frequency bands, thereby changing the operational parameters to eliminate harmful interference while preserving network adaptability.
2Reliability
If interfering wireless signals are detected and reassigned to different frequency bands, then interference is mitigated and communication quality improves, but additional network control and coordination are required
Solution Approach 1:
The patent introduces a network entity (such as a core network entity or controlling base station) that acts as an intermediary to coordinate interference management between different mobile networks. This intermediary receives interference reports, determines appropriate frequency band reassignments, and sends control instructions to relevant base stations, thereby centralizing control logic and reducing overall system complexity.
Solution Approach 2:
The patent implements a universal interference management mechanism that can handle multiple types of inter-band interference scenarios across different mobile networks and frequency band combinations. The same detection and reassignment protocol works universally for various interference conditions, reducing the need for network-specific customization and simplifying deployment across diverse network configurations.
