Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum sensing parameters are adjusted to increase the probability of obtaining unlicensed frequency band resources, then spectrum utilization efficiency is improved, but interference with existing systems may increase
Solution Approach 1:
The patent implements dynamic adjustment of spectrum sensing parameters (such as energy detection thresholds and sensing durations) based on real-time spectrum utilization information. The spectrum management apparatus continuously monitors spectrum usage patterns and adapts sensing parameters to optimize the balance between acquiring unlicensed band resources and protecting existing systems from interference, rather than using fixed threshold values.
Solution Approach 2:
The patent establishes a feedback mechanism where the spectrum management apparatus receives spectrum utilization information from multiple wireless communication systems, analyzes the data to determine spectrum utilization efficiency, and adjusts sensing parameters accordingly. This closed-loop feedback system enables continuous optimization of spectrum access while minimizing harmful interference to existing communications.
2Productivity
If multiple wireless communication systems share unlicensed frequency bands, then spectrum resource utilization is improved, but fair and effective usage becomes more difficult to manage
Solution Approach 1:
The patent introduces a spectrum management apparatus as an intermediary between multiple wireless communication systems sharing unlicensed frequency bands. This centralised management entity collects spectrum utilization information from all systems, analyzes the data to determine usage efficiency, and coordinates parameter adjustments to ensure fair and effective spectrum sharing, thereby reducing the complexity that would otherwise arise from uncoordinated multi-system operation.
Solution Approach 2:
The spectrum management apparatus performs multiple functions including acquiring spectrum utilization information from different systems, analyzing spectrum usage patterns, determining utilization efficiency metrics, and adjusting sensing parameters for multiple systems simultaneously. This multi-functional approach consolidates what would otherwise be separate management tasks into a single coordinated system.
