Radio Resource Management for Spectrum Allocation Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource management systems face challenges in allocating spectrum resources to new secondary systems without interfering with primary systems and considering interference from adjacent secondary systems, leading to inefficient resource utilization and potential quality of service (QoS) issues.
Innovation Solution
A radio resource management system that acquires interference information from various locations and determines whether to accept a new secondary system's request based on this information, ensuring that the secondary systems opportunistically use authorized spectrum resources while meeting predetermined interference conditions, and adjusts modulation modes and operating parameters to guarantee QoS requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If spectrum resources are allocated to new secondary systems without considering interference from adjacent systems, then resource allocation speed is improved, but interference management and QoS reliability deteriorate
Solution Approach 1:
The patent applies preliminary action by having the radio resource management system proactively acquire interference information from adjacent systems before making spectrum resource allocation decisions. This allows the system to predict potential interference issues and make informed allocation decisions in advance, maintaining both fast allocation speed and reliable interference management.
Solution Approach 2:
The patent implements feedback mechanisms where interference information from adjacent radio resource management systems is continuously acquired and used to adjust spectrum resource allocation decisions. This feedback loop ensures that allocation decisions consider current interference conditions, maintaining reliability while preserving allocation speed through efficient information utilization.
2Reliability
If interference information from adjacent radio resource management systems is acquired, then interference management reliability is improved, but system complexity and information processing requirements worsen
Solution Approach 1:
The patent applies universality by designing the radio resource management system to handle multiple functions through a unified architecture. The same system components that manage local interference also process information from adjacent systems, eliminating the need for separate dedicated modules and reducing overall system complexity while maintaining reliable interference management.
Solution Approach 2:
The patent merges the interference management functions for local and adjacent systems into a single integrated process. By combining information acquisition, analysis, and decision-making into one unified system operation, the patent reduces the complexity that would arise from separate handling mechanisms while ensuring comprehensive interference management reliability.
3Productivity
If spectrum resources are allocated without considering QoS requirements, then resource allocation efficiency is improved, but service quality and user satisfaction deteriorate
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting spectrum resource allocation based on QoS requirements of different services. The system modifies allocation parameters such as bandwidth, power, and time resources according to service priorities and quality demands, ensuring both efficient resource utilization and reliable QoS guarantees through adaptive parameter optimization.
