Dynamic Spectrum Allocation for Secondary Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the allocation of frequency spectrum resources is inefficient due to historical inheritance and constraints from network density, layout complexity, and priority differences, leading to suboptimal usage and interference between primary and secondary systems.
Innovation Solution
A frequency spectrum resource management apparatus and method that acquires available and occupied frequency spectrum information to adjust spectrum usage dynamically, transferring resources between secondary systems to optimize throughput and reduce interference, ensuring efficient use without affecting primary systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frequency spectrum resources are allocated to secondary systems under historical inheritance and constraint conditions, then allocation fairness is maintained, but utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic frequency spectrum resource allocation by establishing a feedback mechanism that continuously monitors spectrum usage status. The system dynamically adjusts allocation decisions based on real-time information about primary and secondary system usage patterns, allowing the allocation strategy to adapt to changing network conditions rather than relying on static historical constraints
Solution Approach 2:
The patent introduces a feedback mechanism where the frequency spectrum resource management apparatus receives information about actual spectrum usage by primary and secondary systems. This feedback loop enables the system to evaluate allocation effectiveness and make iterative improvements, comparing actual usage against allocated resources to identify and correct inefficiencies
2Productivity
If frequency spectrum resources are allocated considering network density and layout complexity, then allocation fairness is maintained, but allocation optimality deteriorates
Solution Approach 1:
The patent segments the frequency spectrum resource management into distinct functional components: a frequency spectrum resource management apparatus that handles allocation decisions, primary system apparatuses that manage licensed spectrum, and secondary system apparatuses that access unlicensed spectrum. This segmentation allows each component to operate independently with specialized logic, reducing overall system complexity while improving allocation optimality
Solution Approach 2:
The patent changes the allocation parameters from static historical constraints to dynamic usage-based parameters. The system monitors actual spectrum usage patterns and adjusts allocation decisions accordingly, transitioning from fixed allocation rules to flexible parameter-driven allocation that adapts to current network conditions and optimizes resource distribution
3Productivity
If frequency spectrum resources are allocated under priority constraints, then primary system protection is maintained, but secondary system utilization deteriorates
Solution Approach 1:
The patent applies partial action by allowing secondary systems to access frequency spectrum resources only when primary systems are not actively using them, rather than providing full unrestricted access. The system partially allocates spectrum to secondary systems based on real-time primary system usage patterns, maximizing secondary utilization while maintaining primary protection through selective rather than comprehensive allocation
Solution Approach 2:
The patent implements self-service mechanisms where secondary systems autonomously monitor primary system usage and independently make allocation requests. The frequency spectrum resource management apparatus automatically evaluates these requests against current primary system status and grants or denies access accordingly, creating a self-regulating system that balances secondary utilization with primary protection without requiring centralized intervention
