Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadband wireless networks, such as IEEE 802.16, face limitations in group resource allocation, particularly in supporting high mobility and low latency applications, due to restrictive frame structures that hinder efficient communication and resource allocation across diverse mobile stations operating in different modes.
Innovation Solution
The implementation of a modified frame structure and group resource allocation technique that allows for dynamic grouping and resource allocation of mobile stations, enabling efficient communication and resource management across stations operating in various multiple input multiple output (MIMO) modes, while maintaining backward compatibility with existing standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If group resource allocations are limited to groupings of mobile stations operating in a same mode, then resource allocation overhead is reduced, but adaptability to diverse mobile stations operating in different modes deteriorates
Solution Approach 1:
The patent segments mobile stations into different groups based on their operational modes (e.g., MIMO modes). Each group is assigned dedicated resource allocation parameters and configurations. This segmentation allows the system to manage complexity by handling each mode separately while still supporting diverse mobile stations through multiple segmented groups, thus resolving the contradiction between reduced overhead and improved adaptability.
2Adaptability or versatility
If frame structure is restrictive to maintain standard compatibility, then backward compatibility is ensured, but support for high mobility and low latency applications deteriorates
Solution Approach 1:
The patent introduces dynamic elements within the frame structure that allow adaptation to high mobility scenarios while preserving the overall standard-compliant framework. Specifically, it enables dynamic resource allocation adjustments, flexible timing configurations, and adaptive parameter modifications within each frame based on detected mobility conditions. This dynamic capability allows the system to support low latency applications without breaking backward compatibility, as the core structure remains standard-compliant while internal parameters can adapt dynamically.
