Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently allocating limited transmission resources to meet the demands of high-speed and high-quality services, particularly due to the scarcity and high cost of new frequency spectrum resources, necessitating innovative methods for dynamic spectrum utilization between primary and secondary systems.
Innovation Solution
A method and apparatus that effectively allocate transmission resources for secondary systems by estimating geographic distribution density, clustering secondary systems, and determining available resources based on priority levels and interference considerations, optimizing resource utilization and minimizing interference with primary systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic spectrum utilization is implemented to allocate frequency spectrum resources to secondary systems, then transmission resource efficiency is improved, but interference with primary systems increases
Solution Approach 1:
The patent applies local quality by clustering secondary systems based on their geographic distribution density and assigning different available resources to different clusters. This allows resource allocation to be tailored to specific geographic locations and interference conditions, optimizing transmission resource efficiency while controlling interference with primary systems on a local basis rather than uniformly across all secondary systems.
Solution Approach 2:
The patent implements dynamics by determining available resources dynamically based on the geographic distribution density of secondary systems and their cluster assignments. The resource allocation is not static but adapts to changing conditions in the wireless communication environment, allowing the system to respond to varying interference conditions and resource availability in real-time.
2Reliability
If frequency spectrum resources are allocated to secondary systems, then service quality and speed are improved, but resource scarcity and cost increase
Solution Approach 1:
The patent applies merging by clustering multiple secondary systems into groups based on geographic distribution density and having them share available resources. This consolidates resource allocation efforts and allows secondary systems to collectively utilize frequency spectrum resources more efficiently, improving service quality while managing the limited quantity of available resources.
Solution Approach 2:
The patent changes parameters by determining available resources based on geographic distribution density and cluster assignments. The allocation parameters are adjusted according to the specific conditions of each secondary system cluster, allowing optimization of service quality and speed while adapting to the constraints of frequency spectrum resource scarcity.
3Speed
If transmission resources are allocated to meet high-speed communication demands, then communication speed is improved, but transmission resource consumption increases
Solution Approach 1:
The patent applies partial action by allocating available resources selectively to secondary system clusters based on their geographic distribution density and specific needs. Rather than allocating resources uniformly or excessively to all secondary systems, the patent provides partial resource allocation tailored to each cluster's requirements, achieving high-speed communication where needed while conserving transmission resources.

AI summary
A system that identifies a number of secondary systems located in a first geographical area; identifies a primary resource available to be assigned to the secondary systems, the primary resource being a resource to which a primary system has a priority usage right; determines whether the number of secondary systems located in the first geographical area exceeds a predetermined threshold value; and limits a number of secondary systems to which the primary resource is assigned when it is determined that the number of secondary systems located in the first geographical area exceeds the predetermined threshold value.
