Inter-Service Information Sharing for V2X Parameter Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems for vehicle-to-everything (V2X) applications face challenges in dynamically configuring essential parameters like MCS, antenna ports, and reference signal patterns due to high mobility and lack of network infrastructure, leading to inefficiencies in parameter setting and increased overhead.
Innovation Solution
Vehicles can autonomously determine and configure transmission and reception parameters based on information from surrounding vehicles, leveraging inter-service information sharing between different radio access technologies (RATs) like LTE V2X and NR V2X to enhance performance and reduce overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wireless communication systems configure essential parameters at network control, then parameter setting is simplified, but the system cannot adapt to high mobility and lacks responsiveness in V2X applications
Solution Approach 1:
The patent enables wireless devices to autonomously configure essential physical layer parameters (number of antenna ports, number of MIMO layers, MCS, reference signal patterns) based on their own perceived input and information received from other devices, eliminating dependency on network infrastructure for parameter configuration
Solution Approach 2:
The system uses feedback from channel conditions, interference levels, and service requirements to dynamically adjust parameters. Devices monitor their communication environment and adapt parameters based on this feedback to maintain optimal performance in high-mobility V2X scenarios
2Reliability
If vehicles use autonomous parameter configuration, then network dependency is reduced, but parameter setting efficiency and coordination become more challenging
Solution Approach 1:
The patent pre-configures parameter sets based on different service types and mobility conditions. Devices can quickly select from pre-defined parameter combinations rather than calculating optimal parameters in real-time, reducing configuration time while maintaining reliability
Solution Approach 2:
The system merges parameter configuration for multiple services into a coordinated framework. By combining parameter selection across different services and layers, the system achieves efficient coordination without requiring extensive negotiation time between devices
3Productivity
If dynamic parameter adjustment is implemented, then communication efficiency improves, but system complexity and overhead increase
Solution Approach 1:
The patent implements dynamic parameter adjustment where devices can change physical layer parameters based on current channel conditions, mobility state, and service requirements. This enables the system to adapt to varying communication demands while maintaining manageable complexity through structured parameter selection frameworks
4Reliability
If inter-service information sharing is implemented, then service performance is enhanced, but information processing overhead increases
Solution Approach 1:
The patent extracts only the essential information needed for parameter configuration from inter-service data. Rather than processing all available service information, the system identifies and uses only the critical parameters (channel conditions, mobility indicators, service type) needed for efficient physical layer configuration, reducing information overhead
