Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication configurations in radio-assisted road traffic management scenarios, particularly for autonomous driving, are suboptimal in meeting specific requirements such as latency and reliability, especially in switching between broadcast, multicast, and unicast modes.
Innovation Solution
A method and apparatus for managing radio communication parameters in road traffic scenarios by detecting specific road conditions and transmitting configuration signaling to adjust radio communication modes, such as switching between vehicle-to-vehicle and vehicle-to-infrastructure communication modes, using a processor and memory with computer program code to optimize radio communication characteristics based on traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio communication configurations are optimized for autonomous driving requirements, then latency and reliability are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The system enables autonomous driving MTC devices to self-configure radio communication parameters by autonomously switching between broadcast, multicast, and unicast modes based on detected road traffic conditions, eliminating the need for manual configuration and reducing complexity while maintaining high reliability
Solution Approach 2:
The patent implements dynamic configuration of radio communication parameters that adapt in real-time to changing road traffic conditions, allowing the system to optimize latency and reliability without fixed complex pre-configuration by continuously adjusting communication modes based on current operational context
2Productivity
If radio communication modes are switched dynamically based on traffic conditions, then communication performance is improved, but control and coordination difficulty increase
Solution Approach 1:
The system employs feedback mechanisms where autonomous driving MTC devices detect road traffic conditions and use this information to determine appropriate radio communication modes, creating a closed-loop control system that automatically optimizes communication efficiency without requiring complex external coordination
Solution Approach 2:
The patent introduces road traffic conditions as an intermediary parameter that mediates the selection between different radio communication modes, simplifying the control logic by using observable traffic state (such as vehicle density, speed, and spacing) to automatically determine whether broadcast, multicast, or unicast mode should be used
3Reliability
If advanced processing power is deployed at network edge, then radio communication requirements are met, but infrastructure cost and energy consumption increase
Solution Approach 1:
The patent implements local processing at the network edge through Road Side Units that handle radio communication configuration and mode switching decisions, distributing computational load from centralized cloud infrastructure to local edge nodes, thereby meeting strict radio requirements while reducing overall network energy consumption by processing data closer to the source

AI summary
There are provided measures for configuration of radio communication in radio-assisted road traffic management scenarios. Such measures exemplarily comprise (for managing a predetermined area in a radio-assisted road traffic management scenario) detecting a specific road traffic condition in said predetermined area, and transmitting a configuration signaling instructing a configuration of at least one radio communication related parameter.
