Engineering Contradiction Analysis
1Stability of the object's composition
If frequency spectrum resources are allocated to fixed operators and services, then service stability is improved, but frequency spectrum utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic frequency spectrum allocation where secondary systems can dynamically access licensed frequency spectrum according to certain rules. The system allows frequency resources to be reallocated based on actual usage conditions, enabling the transition from fixed static allocation to dynamic flexible allocation, thus improving overall utilization efficiency while maintaining primary system stability
Solution Approach 2:
The patent changes the allocation parameters of frequency spectrum resources by introducing a distribution coefficient that represents interference degree. This coefficient is used to adjust the frequency spectrum distribution for secondary systems, allowing the system to optimize resource allocation by modifying allocation parameters based on interference conditions and utilization efficiency requirements
2Productivity
If secondary systems dynamically access licensed frequency spectrum, then frequency spectrum utilization efficiency is improved, but aggregation interference against primary system worsens
Solution Approach 1:
The patent implements a feedback mechanism where the frequency spectrum management device determines distribution coefficients based on the aggregation interference generated by secondary systems. The system continuously monitors interference levels and adjusts the frequency spectrum distribution accordingly, creating a closed-loop control that balances utilization efficiency with interference control
Solution Approach 2:
The patent introduces and utilizes the distribution coefficient as a key parameter to control aggregation interference. By calculating and adjusting this coefficient based on interference conditions, the system optimizes frequency spectrum distribution to minimize harmful effects on primary systems while maintaining efficient resource utilization
3Adaptability or versatility
If frequency spectrum is allocated to multiple secondary systems, then service coverage is expanded, but interference control difficulty increases
Solution Approach 1:
The patent simplifies interference control by introducing the distribution coefficient as a unified parameter that captures the interference characteristics of multiple secondary systems. This single parameter approach allows the management device to control aggregation interference from multiple sources through a standardized mechanism, reducing the complexity of managing multiple interfering sources
