Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed antenna is used to perform sensing service, then device complexity is reduced, but sensing performance degrades due to changing environmental conditions and target statuses
Solution Approach 1:
The patent implements dynamic antenna selection where the sensing device switches between different antennas based on real-time target information and environmental conditions. The network-side device determines antenna selection information dynamically and sends it to the sensing device, enabling the system to adapt to changing sensing conditions while maintaining manageable complexity through centralized control.
2Reliability
If antenna selection is implemented based on target information, then sensing performance improves, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The network-side device serves as an intermediary that centralizes the antenna selection decision-making process. It receives target information, determines the appropriate antenna selection information, and sends it to the sensing device. This intermediary approach improves sensing performance through informed antenna selection while managing complexity by centralizing the control logic in the network-side device rather than distributing it across multiple sensing devices.
3Measurement precision
If adaptive antenna selection is implemented, then sensing accuracy improves, but information processing requirements increase
Solution Approach 1:
The patent extracts only the essential target information needed for antenna selection from the complete sensing data set. The network-side device determines antenna selection information based on relevant target characteristics without processing the entire data set, thereby improving sensing accuracy through selective information use while reducing the overall information processing load.
