Wireless Resource Management for Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication scenarios where primary and secondary systems coexist, there is a challenge in assigning communication resources to secondary systems without causing adverse interference to primary systems, especially when multiple secondary systems are involved.
Innovation Solution
A resource management apparatus is configured to acquire interference information from other resource management apparatuses, determine communication resources for managed systems based on this information, and notify the corresponding systems. This apparatus recognizes managed and non-managed systems, determines mutual interferences, and generates interference information to optimize resource assignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If secondary systems dynamically utilize spectrum resources allocated to primary systems, then communication resource utilization is improved, but interference to primary systems increases
Solution Approach 1:
The patent implements a feedback mechanism where the primary system reports interference levels to the secondary system. The secondary system's base station receives interference information from the primary system's base station and adjusts resource allocation accordingly. This closed-loop feedback enables dynamic spectrum sharing while maintaining interference within acceptable thresholds, resolving the contradiction between resource utilization and interference control.
Solution Approach 2:
The patent changes key parameters including interference thresholds, resource allocation ratios, and power levels based on real-time system conditions. The primary system sets an interference threshold parameter that dynamically controls the maximum allowable interference to secondary systems. By adjusting these parameters adaptively, the system optimizes resource utilization while preventing harmful interference to primary communications.
2Productivity
If multiple secondary systems share spectrum resources, then overall system capacity is improved, but aggregated interference to primary system increases
Solution Approach 1:
The patent merges the interference management of multiple secondary systems into a unified control framework. The primary system's base station aggregates interference information from all secondary systems and communicates a collective interference threshold to coordinate their resource usage. This merging approach enables multiple secondary systems to share spectrum resources while their combined interference remains controlled through centralized coordination.
Solution Approach 2:
The patent introduces dynamic resource allocation where secondary systems continuously adjust their spectrum usage based on real-time interference conditions. The system transitions from static to dynamic control, with base stations exchanging interference information and adapting resource allocation parameters on-the-fly. This dynamic behavior allows multiple secondary systems to coexist by adapting their resource usage to current system conditions, maintaining high capacity while controlling aggregated interference.
3Ease of operation
If secondary systems are allowed to communicate without strict interference control, then ease of operation is improved, but communication quality of primary system deteriorates
Solution Approach 1:
The patent introduces base stations as intermediary entities that mediate between secondary systems and primary systems. Rather than requiring direct complex interference control between end devices, the base stations act as intermediaries that exchange interference information and coordinate resource allocation. This intermediary layer simplifies operation for secondary systems while ensuring primary system quality through centralized interference management at the base station level.
