Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static association between terminal equipment and RIS is used to form boosted areas, then network configuration is simplified, but quality of service deteriorates when terminal equipment moves
Solution Approach 1:
The patent applies dynamics by transitioning from static RIS associations to dynamic associations. The network determines updated trajectories for terminal equipment and identifies new boosted areas along these trajectories, allowing the system to adapt to movement and changing conditions while maintaining service quality.
Solution Approach 2:
The patent uses preliminary action by determining expected trajectories of terminal equipment in advance and pre-identifying boosted areas along these trajectories. This allows the network to prepare control information for RIS reconfiguration before the terminal actually moves, ensuring continuous optimal service.
2Ease of manufacture
If static boosted areas are deployed for identified focused geographical areas, then network deployment is simplified, but performance becomes sub-optimal in dynamic environments
Solution Approach 1:
The system transforms static boosted areas into dynamic boosted areas by continuously updating their positions and configurations based on terminal equipment trajectories and service requirements, thereby maintaining high performance in dynamic environments while keeping deployment procedures relatively simple.
Solution Approach 2:
The patent changes parameters of boosted areas dynamically, including their positions, shapes, and associated RIS configurations, based on real-time trajectory predictions and service needs, allowing the network to optimize performance without redeploying infrastructure.
3Area of stationary object
If terminal equipment moves in coverage area, then service coverage is improved, but quality of service deteriorates due to static RIS associations
Solution Approach 1:
The system maintains reliable quality of service during terminal movement by dynamically updating RIS associations and boosted area configurations along the terminal's trajectory, ensuring continuous optimal performance across the expanded coverage area.
