Adaptive V2X Reporting Interval Based on Vehicle Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE-based V2X environments, there is a need for efficient reporting of geographic information by vehicle user equipment (UE) to optimize resource allocation for V2X communication, as existing methods do not adaptively manage reporting intervals based on vehicle speed, leading to suboptimal resource utilization and communication efficiency.
Innovation Solution
A method and apparatus that configure a reporting interval for geographic information based on the speed of the vehicle UE, allowing periodic transmission of this information to the network, enabling adaptive resource allocation and improved communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If geographic information is transmitted frequently to ensure accurate resource allocation, then resource allocation accuracy is improved, but network signaling overhead and energy consumption increase
Solution Approach 1:
The reporting interval is dynamically adjusted based on vehicle speed. When vehicle speed exceeds a threshold, the reporting interval is extended (reduced frequency), and when speed is below the threshold, the reporting interval is shortened (increased frequency). This dynamic adaptation maintains resource allocation accuracy for high-speed vehicles while reducing unnecessary signaling overhead and energy consumption.
Solution Approach 2:
The system changes the reporting interval parameter according to vehicle speed conditions. By modifying this temporal parameter based on speed measurements, the system optimizes the balance between location update accuracy and network overhead, ensuring that geographic information is reported frequently enough for accurate resource allocation while minimizing energy waste from excessive reporting.

3Device complexity
If a fixed reporting interval is used for all vehicles, then system complexity is reduced, but communication efficiency deteriorates due to inability to adapt to different speed conditions
Solution Approach 1:
The system implements dynamic adjustment of the reporting interval based on real-time vehicle speed measurements. This allows the system to adapt to different communication scenarios (high-speed vs. low-speed vehicles) without requiring complex manual configuration, thereby improving communication efficiency while maintaining manageable system complexity through automated speed-based decision making.

AI summary
An in-vehicle terminal engaged in vehicle-to-everything (V2X) communication, especially vehicle-to-vehicle (V2V) communication, establishes a reporting cycle on the basis of the speed of the in-vehicle terminal, and transmits geographic information of the in-vehicle terminal to a network cyclically on the basis of the reporting cycle. That is, the reporting cycle may be shortened as the in-vehicle terminal speed increases, or may be lengthened as the in-vehicle terminal speed decreases.
