Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If UAVs communicate with more ground-based network entities, then communication coverage is improved, but uplink interference increases
Solution Approach 1:
The service area is divided into multiple three-dimensional zones based on altitude coordinates. Each zone is associated with a specific ground-based network entity, allowing UAVs to be served by the most appropriate entity based on their vertical position. This segmentation reduces the number of UAVs each ground entity must serve, thereby reducing uplink interference while maintaining comprehensive coverage.
Solution Approach 2:
The patent introduces altitude as a third dimension for zone differentiation, moving beyond traditional two-dimensional geographic segmentation. By defining three-dimensional zones with altitude ranges, the system can assign UAVs to different ground-based network entities based on their vertical position, effectively managing interference in the uplink direction while preserving extensive communication coverage.
2Adaptability or versatility
If UAVs have more handover candidates, then connectivity options are improved, but network resource waste increases due to unnecessary handovers
Solution Approach 1:
Different mobile network settings are applied to different three-dimensional zones. Each zone has optimized handover parameters and connectivity options tailored to its specific characteristics. When a UAV enters a new zone, it receives localized configuration that balances connectivity options with resource conservation, preventing unnecessary handovers while maintaining adaptability to local network conditions.
Solution Approach 2:
The system pre-configures mobile network settings for each three-dimensional zone before UAVs enter them. By determining the appropriate handover candidates and connectivity parameters in advance for each zone, the system enables UAVs to make informed connection decisions without experiencing excessive handover activity, thereby reducing network resource waste while preserving connectivity options.
3Device complexity
If standard mobile network settings are used for all UAVs, then system complexity is reduced, but spectral efficiency deteriorates
Solution Approach 1:
Mobile network settings are made dynamic and adaptive to the UAV's spatial location rather than being static and uniform. The system automatically adjusts handover parameters, connectivity options, and other network settings based on which three-dimensional zone the UAV currently occupies. This dynamic approach significantly improves spectral efficiency by optimizing settings for each local condition while adding minimal complexity through automated zone-based configuration.
