PRB Bundling Coordination for Wireless Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, existing technologies face challenges in efficiently coordinating PRB bundling between neighboring cells, leading to resource wastage and suboptimal performance due to varying data sizes and interference management.
Innovation Solution
A method for coordinating PRB bundling by sharing traffic information between cells to determine the minimum required resources for bundling, using a bitmap method or RRC signaling to notify user equipment, and applying PRB bundling based on traffic ratios, thereby optimizing resource allocation and interference rejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If PRB bundling is applied independently in each cell without coordination, then each cell can optimize its own resource allocation, but resource wastage occurs and system performance deteriorates due to interference and mismatched bundling configurations
Solution Approach 1:
The patent merges the PRB bundling decisions of multiple cells by coordinating the bundling configurations across neighboring cells. This ensures that PRBs at cell boundaries are bundled in a consistent manner, reducing inter-cell interference and improving resource utilization efficiency without causing resource wastage.
Solution Approach 2:
The patent applies different bundling strategies to different regions: coordinated bundling is applied at cell boundaries where interference is critical, while independent optimization can be applied in other regions. This localized approach resolves the contradiction by improving productivity at critical interfaces without unnecessarily constraining other areas.
2Productivity
If PRB bundling coordination is implemented between neighboring cells, then resource allocation efficiency improves and resource wastage reduces, but system complexity increases due to information sharing and coordination mechanisms
Solution Approach 1:
The patent introduces a coordination mechanism that acts as an intermediary between neighboring cells. This mediator facilitates information exchange about traffic conditions and bundling configurations, enabling coordinated resource allocation without requiring direct complex interactions between all cells, thus managing system complexity.
Solution Approach 2:
The patent changes the parameter of information sharing between cells, transitioning from no information exchange to selective sharing of traffic information and bundling configurations. This controlled parameter change enables coordination benefits while managing complexity by sharing only essential parameters rather than complete system states.
3Device complexity
If PRB bundling is applied without considering traffic information sharing, then implementation is simpler, but channel estimation accuracy deteriorates and interference management becomes suboptimal
Solution Approach 1:
The patent applies preliminary action by having cells share traffic information and determine bundling configurations in advance before actual data transmission. This allows UEs to perform accurate channel estimation and interference management based on known bundling patterns, improving measurement precision without requiring complex real-time coordination.
