Solution Overview
Problem
Current wireless spectrum resource allocation methods result in uneven distribution, leading to low utilization due to inefficient allocation, where some operators have excess resources while others lack sufficient resources, causing service processing inefficiencies.
Innovation Solution
A base station device is equipped with a transmitter to release spectrum resource requirement information and a processor to receive authorization messages, allowing for the dynamic allocation and sharing of wireless spectrum resources between devices based on actual needs, improving resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless spectrum resources are allocated to operators using conventional FDM manner, then each operator can deploy base stations and provide services, but the allocation becomes uneven leading to low utilization with some operators having idle resources while others face resource insufficiency
Solution Approach 1:
The patent merges spectrum resources from multiple operators into a shared pool, allowing dynamic allocation. Base stations from different operators can access and share the same spectrum resources through coordinated multipoint transmission, transforming isolated operator-specific resources into collectively usable resources that improve overall utilization efficiency.
Solution Approach 2:
The patent implements dynamic spectrum resource allocation where the allocation is not fixed but adjusts in real-time based on service demands. The system dynamically assigns spectrum resources to different base stations and operators according to current traffic conditions, enabling flexible adaptation to changing requirements while maximizing resource utilization.
2Productivity
If more wireless spectrum resources are allocated to certain operators to meet their service demands, then service processing capacity increases for those operators, but spectrum resources become insufficient for other operators leading to low service processing efficiency
Solution Approach 1:
The patent makes spectrum resources universal by creating a shared resource pool that serves multiple operators and base stations. The same spectrum resources can be dynamically allocated to different operators based on their instantaneous service needs, allowing one set of resources to fulfill multiple functions and serve multiple purposes simultaneously.
Solution Approach 2:
The patent changes the allocation parameters of spectrum resources dynamically rather than maintaining fixed assignments. By adjusting allocation parameters in real-time based on service demands, the system can increase capacity for operators needing more resources while temporarily reducing allocations for others, optimizing the overall distribution of limited spectrum resources.
3Ease of operation
If conventional fixed allocation of wireless spectrum resources is used, then allocation simplicity is maintained, but resource utilization becomes inefficient due to uneven distribution and idle resources
Solution Approach 1:
The patent implements feedback mechanisms where base stations report their spectrum resource usage and service demand status to a central coordination entity. This feedback enables the system to monitor resource utilization in real-time and dynamically adjust allocations to eliminate waste and idle resources while maintaining manageable complexity through automated control.
