Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication technologies face reliability issues due to random resource selection from exceptional resource pools during transmission resource changes, leading to collisions and reduced communication reliability, especially in NR-V2X systems requiring high reliability and data rate.
Innovation Solution
The proposed solution involves selecting an appropriate transmission mode based on data transmission information, using dedicated resources for high-reliability and high-priority data traffic and exceptional resource pools for other types, thereby optimizing data transmission and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If random resource selection from exceptional resource pools is used during transmission resource changes, then device complexity is reduced and ease of operation is improved, but communication reliability deteriorates due to collisions
Solution Approach 1:
The patent applies dynamics by making the transmission mode adaptable and changeable based on real-time conditions. The terminal device dynamically selects between first transmission mode (dedicated resources) and second transmission mode (exceptional resource pool) according to the data traffic characteristics and channel conditions, allowing the system to optimize reliability for different traffic types while managing complexity through conditional logic rather than fixed structures
Solution Approach 2:
The patent applies local quality by differentiating resource allocation strategies for different types of data traffic. High-reliability and high-priority data traffic receives dedicated resources through first transmission mode, while other traffic uses exceptional resource pools through second transmission mode. This localized optimization ensures that critical traffic gets enhanced protection without unnecessarily complicating the overall system for all traffic types
2Reliability
If dedicated resources are allocated for high-reliability data traffic, then communication reliability is improved, but device complexity and resource management overhead increase
Solution Approach 1:
The patent applies segmentation by dividing data traffic into different categories (high-reliability/high-priority vs. other traffic) and allocating resources through different transmission modes accordingly. This segmentation allows dedicated resources to be assigned only where needed for critical traffic, rather than universally, thereby improving reliability for important data while avoiding unnecessary complexity for the entire system
Solution Approach 2:
The patent applies parameter changes by adjusting transmission mode selection based on traffic parameters such as reliability requirements and priority levels. The system changes operational parameters (transmission mode, resource allocation strategy) dynamically according to traffic characteristics, enabling optimized reliability for high-priority traffic while managing complexity through parameter-based control rather than structural overhead
3Productivity
If exceptional resource pools are used for all data traffic, then device complexity is minimized and ease of operation is maximized, but transmission efficiency and reliability deteriorate for high-priority traffic
Solution Approach 1:
The patent applies local quality by applying different resource selection strategies to different traffic types. Periodic data traffic with predictable patterns utilizes exceptional resource pools through second transmission mode, maintaining operational simplicity. Meanwhile, high-priority traffic receives enhanced treatment through first transmission mode with dedicated resources, improving transmission efficiency where needed without compromising overall system simplicity
