Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sounding reference signals are transmitted towards multiple sensing areas, then sensing coverage and capability are improved, but transmission power management becomes complex and interference increases
Solution Approach 1:
The patent segments the sounding reference signal resources into multiple resource sets, where each resource set is dedicated to a specific sensing area or target object type. This segmentation allows independent power control for each resource set, simplifying the overall power management complexity while maintaining comprehensive sensing coverage across multiple areas.
Solution Approach 2:
The patent implements local quality by configuring different transmission power control parameters for different sounding reference signal resource sets. Each resource set can have its own power control settings optimized for specific sensing requirements, target objects, or interference conditions in particular areas, rather than using a uniform power control approach system-wide.
2Measurement precision
If transmission power is increased for better sensing accuracy, then measurement precision improves, but interference to other areas and target objects increases
Solution Approach 1:
By dividing the sounding reference signal resources into separate resource sets for different sensing areas and target objects, the patent enables targeted power transmission. Each resource set can transmit at optimized power levels for its specific purpose without unnecessarily increasing interference to other areas, thus maintaining measurement precision while reducing harmful interference.
Solution Approach 2:
The patent applies local quality through area-specific power control parameters that allow each sensing area to receive appropriate transmission power for accurate measurement. This localized power optimization ensures that power is increased only where needed for sensing accuracy, rather than uniformly across all areas, thereby minimizing interference generation.
3Measurement precision
If separate resource sets are configured for different target objects, then sensing specificity and accuracy improve, but configuration complexity increases
Solution Approach 1:
The patent implements a universal power control framework that can be applied across multiple sounding reference signal resource sets. The same power control mechanism and parameter structure are reused for each resource set, allowing the system to achieve high sensing specificity for different target objects while avoiding proportional increases in configuration complexity through standardized multi-functional power control procedures.
