Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensing signal transmission uses conventional resource allocation methods, then system compatibility is maintained, but sensing measurement precision and transmission reliability are insufficient
Solution Approach 1:
The patent segments the sensing signal transmission resources into distinct time-domain resource elements and frequency-domain resource elements, organizing them into structured resource sets. This segmentation allows for optimized allocation of time-frequency resources specifically for sensing measurements, improving measurement precision while maintaining manageable configuration complexity through systematic organization.
Solution Approach 2:
The patent introduces a dedicated time-frequency resource dimension for sensing signals, separate from conventional communication resources. By allocating specific time-domain resource elements and frequency-domain resource elements for sensing purposes, the system creates an additional resource allocation layer that enhances sensing measurement precision without interfering with existing communication operations.
2Reliability
If sensing signal transmission uses dedicated time-frequency resource patterns, then transmission reliability improves, but resource allocation complexity increases
Solution Approach 1:
The patent divides sensing signal resources into discrete time-domain resource elements and frequency-domain resource elements, forming structured resource sets. This segmentation enables reliable sensing transmission by ensuring dedicated resource allocation, while the modular structure keeps configuration complexity manageable through systematic organization of resource elements.
Solution Approach 2:
The patent creates resource set configurations that can serve multiple sensing measurement purposes (velocity, distance, angle estimation) while maintaining a unified time-frequency resource pattern structure. This multi-functionality approach improves transmission reliability across different sensing applications without proportionally increasing configuration complexity.
3Measurement precision
If multiple time-domain resource elements are allocated for sensing signals, then velocity and Doppler estimation accuracy improves, but time resource consumption increases
Solution Approach 1:
The patent segments time-domain resources into multiple discrete time-domain resource elements within resource sets, specifically allocated for sensing signal transmission. This segmentation enables accurate velocity and Doppler estimation through multiple time samples, while the structured organization optimizes time resource consumption by eliminating waste and ensuring each time element serves a specific measurement purpose.
