Transmission Device Dynamic Slice Distribution for Error Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission systems do not effectively improve the reception status of reception devices, as they rely on unchanged availability information to manage error occurrences across multiple transmission paths, leading to inefficiencies and potential errors.
Innovation Solution
A transmission device that receives availability information for multiple transmission paths and dynamically distributes transmission blocks into slices, adjusting distribution based on error occurrence thresholds to optimize data transmission across paths with varying error rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same slice is transmitted to multiple transmission paths regardless of error status, then transmission coverage is maintained, but error propagation increases and reception reliability deteriorates
Solution Approach 1:
The patent applies local quality by transmitting different slices to different transmission paths based on their specific error characteristics. Each transmission path receives customized slice assignments where paths with lower error rates receive slices containing more important or error-sensitive data, while paths with higher error rates receive slices with more redundant or error-tolerant data. This localized adaptation to each path's quality resolves the contradiction between maintaining reception reliability and adapting to varying transmission path conditions.
Solution Approach 2:
The patent implements dynamics by dynamically adjusting slice distribution across transmission paths based on real-time or measured error rates. The system continuously monitors transmission path quality and reconfigures which slices are sent to which paths, allowing the transmission strategy to adapt dynamically to changing channel conditions. This dynamic reconfiguration resolves the contradiction by enabling the system to maintain reliability through adaptive path selection rather than static uniform distribution.
2Reliability
If different slices are transmitted to each transmission path based on error rates, then reception reliability improves, but transmission complexity and processing overhead increase
Solution Approach 1:
The patent applies segmentation by dividing the overall data transmission into multiple slices that can be independently assigned to different transmission paths. Each slice represents a segment of the total data stream with specific error protection characteristics. This segmentation enables the system to manage complexity by treating each slice as an independent unit that can be routed based on simple error rate criteria, rather than managing complex end-to-end error correction across all paths simultaneously.
Solution Approach 2:
The patent implements parameter changes by varying the slice distribution parameters across different transmission paths based on their error rate parameters. The system changes transmission parameters such as slice assignment, redundancy levels, and path selection criteria to match the specific error characteristics of each path. This parameter-based approach resolves the contradiction by providing a systematic method to manage complexity through configurable parameters rather than hard-coded complex routing logic.
3Productivity
If transmission paths with high error rates are used, then transmission capacity is maintained, but error occurrence increases and data integrity deteriorates
Solution Approach 1:
The patent introduces slices as intermediary units between the data source and transmission paths. These slices act as mediators that can be selectively assigned to different paths based on error rates. By using slices as intermediaries, the system can maintain transmission capacity through multiple paths while filtering out high-error paths for sensitive data slices. This intermediary layer resolves the contradiction by decoupling the relationship between transmission capacity and data integrity, allowing each to be optimized independently through slice-based path selection.
