Engineering Contradiction Analysis
1Quantity of substance
If multi-panel antenna is used to support wide frequency bands, then communication capacity and bandwidth are improved, but device complexity and resource allocation difficulty increase
Solution Approach 1:
The patent divides the multi-panel antenna system into independently controllable panels, each capable of being activated or deactivated based on communication requirements. This segmentation allows the system to support wide frequency bands by selectively using only the necessary panels, thereby managing device complexity while maintaining high bandwidth capability.
Solution Approach 2:
The patent implements dynamic panel selection and resource allocation mechanisms that adapt to changing communication conditions. The system can dynamically activate or deactivate panels and adjust resource allocation based on traffic demands, channel conditions, and frequency band requirements, enabling flexible operation across wide frequency bands without permanently maintaining high device complexity.
2Productivity
If panel selection is performed dynamically to improve resource utilization, then communication efficiency is improved, but measurement and control overhead increases
Solution Approach 1:
The patent performs preliminary measurements of panel reception qualities and pre-configures panel selection criteria before actual communication occurs. By advancing measurement and decision-making processes, the system reduces the need for continuous real-time measurements during communication, thereby improving communication efficiency while minimizing measurement overhead.
Solution Approach 2:
The patent implements feedback mechanisms where measurement results from communication nodes are used to inform panel selection decisions. The system collects measurement information, processes it to determine optimal panel configurations, and applies these configurations to improve communication efficiency. This feedback loop enables intelligent resource allocation based on actual channel conditions without requiring excessive continuous measurements.
