V2X Message Transmission Using Risk-Weighted Status Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems face challenges in minimizing battery consumption of vehicle-to-everything user equipment (V2X UE) by effectively quantifying status information into severity levels and determining appropriate message transmission schemes based on these levels.
Innovation Solution
The method involves quantifying status information related to a first V2X UE into multiple severity levels, adjusting transmission and reception periods based on severity levels, and optimizing operations to minimize battery power consumption while ensuring user safety.

Engineering Contradiction Analysis
1Reliability
If a vehicle wants to transmit a message using V2X communication, it needs to send a first signal to obtain transmission permission and wait for a second signal before transmitting, but this causes the vehicle to waste time waiting for the permission signal
Solution Approach 1:
The first vehicle performs preliminary actions by continuously monitoring the second vehicle's signal transmission state and proactively determining transmission permission before the second vehicle actually needs to transmit. This allows the first vehicle to prepare and transmit its message without waiting for the traditional permission signal, thereby reducing time loss while ensuring transmission reliability.
Solution Approach 2:
The system implements feedback mechanisms where the first vehicle monitors the second vehicle's signal transmission state and adjusts its transmission timing accordingly. This feedback loop allows the first vehicle to determine when transmission permission is effectively granted based on real-time signal state information, eliminating the need for explicit permission signals.
2Reliability
If a vehicle transmits messages frequently to ensure communication reliability, then message delivery is improved, but this increases the complexity of signal transmission management
Solution Approach 1:
The first vehicle performs self-service by autonomously monitoring the second vehicle's signal transmission state and independently determining when transmission permission is granted. This self-service mechanism eliminates the need for complex centralized permission management systems, reducing overall system complexity while maintaining reliable message delivery through autonomous transmission decisions.
