Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication networks face challenges in dynamically optimizing the positioning of moving cells to enhance communication and sensing performance, as stationary cells cannot adapt to terminal device positioning, and existing aerial cells are still developing.
Innovation Solution
A set of moving cells, including backhaul and outer moving cells, are controlled by a central trajectory controller to optimize their trajectories, allowing them to dynamically adjust their positions for optimal communication and sensing performance, with backhaul moving cells providing backhaul services to outer moving cells and terminal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stationary cells are used in the network, then network architecture is simple and stable, but communication performance cannot be optimized for moving terminal devices
Solution Approach 1:
The patent implements moving cells that can dynamically change their positions to track and serve terminal devices. The cell structure transitions from static to mobile, allowing the network to adapt to device movements while maintaining organized service through controlled mobility patterns and trajectory management.
Solution Approach 2:
The network is divided into multiple independent moving cells, each capable of autonomous movement and service provision. This segmentation allows individual cells to optimize their positions separately, improving overall network adaptability without requiring complete system reconfiguration.
2Productivity
If moving cells are deployed to track terminal devices, then communication performance is improved, but network control complexity increases
Solution Approach 1:
The network implements feedback mechanisms where terminal device positions are continuously monitored and reported. This feedback information drives the movement decisions of cells, enabling them to automatically adjust their positions to maintain optimal service coverage without complex centralized control.
Solution Approach 2:
Moving cells are equipped with autonomous decision-making capabilities that allow them to self-adjust their positions based on received feedback information. This self-service approach reduces the control burden on the network, as cells independently optimize their own positioning rather than requiring centralized coordination.
3Adaptability or versatility
If cells are moved to optimize coverage, then service to terminal devices is improved, but maintaining stable backhaul connections becomes difficult
Solution Approach 1:
The patent combines multiple cells into coordinated groups that move together while maintaining stable inter-cell connections. By merging the movement behavior of multiple cells, the system achieves both coverage optimization and backhaul stability, as cells within a group maintain fixed relative positions during movement.
Solution Approach 2:
The system introduces intermediate coordination mechanisms that mediate between the need for cell movement and backhaul stability. These intermediaries manage the timing and coordination of cell movements, ensuring that backhaul connections are maintained or reestablished during position changes.
