Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed sensing frame configurations are used, then sensing services can be performed with simple configuration, but time resource redundancy occurs or sensing performance requirements cannot be met
Solution Approach 1:
The patent applies dynamics by making the sensing frame configuration adaptable rather than fixed. The network device dynamically adjusts sensing frame parameters including duration, subcarrier spacing, and cyclic prefix length based on real-time channel conditions and sensing requirements, allowing the system to optimize time resource utilization while maintaining simple operational procedures through automated adaptation.
Solution Approach 2:
The patent implements parameter changes by modifying key sensing frame parameters such as frame duration, subcarrier spacing, and cyclic prefix configuration based on channel quality indicators and sensing performance requirements. This allows the system to transition between different configuration states to eliminate time resource redundancy while ensuring sensing performance is always met.
2Ease of operation
If fixed sensing frame configurations are used, then configuration management is simplified, but sensing performance requirements cannot be met under varying conditions
Solution Approach 1:
The patent implements feedback mechanisms where the network device continuously monitors channel conditions, echo signal quality, and sensing performance metrics. Based on this feedback, the system automatically adjusts sensing frame configurations to maintain reliable sensing performance under varying conditions without requiring manual reconfiguration, thus preserving ease of operation while ensuring performance requirements are met.
Solution Approach 2:
The system transitions from static fixed configurations to dynamic adaptive configurations that respond to changing environmental conditions. The network device adjusts sensing frame parameters in real-time based on detected channel characteristics and sensing requirements, ensuring reliable performance while maintaining simplified operation through automated adaptation.
3Reliability
If sensing slot duration is extended, then sensing performance is improved, but time resource occupation increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the sensing slot duration and other frame parameters based on actual sensing requirements and channel conditions. When sensing performance requirements are met with shorter slots, the system reduces time resource occupation. When higher performance is needed, the system extends slot duration only to the necessary extent, optimizing the balance between performance and time resource utilization.
Solution Approach 2:
The system implements partial action by extending sensing slot duration only to the extent necessary to meet performance requirements, rather than using fixed extended durations. This allows the system to achieve adequate sensing performance with minimal time resource occupation by applying just the right amount of sensing time needed for each specific scenario.
