AI Technical Summary

Technical Problem

In V2X communication, existing service advertisement messages lack efficiency in channel resource management and multichannel access modes, leading to suboptimal service provision and traffic distribution, particularly in environments requiring high reliability for safety services.

Method used

A communication method for V2X devices that includes accessing a channel to receive a network protocol data unit (NPDU) with a service advertisement message (SAM), which provides channel busy ratio (CBR) information and multichannel access mode details, allowing devices to select optimal channels and adjust access modes based on CBR and transmission mode information.

Benefits of technology

This approach enhances channel resource usage efficiency, improves traffic distribution, and enables flexible multichannel access, supporting reliable service provision and efficient operation in V2X communication systems.
