AI Technical Summary

Technical Problem

Traditional congestion control algorithms in vehicular networks struggle to adapt to dynamically changing traffic conditions, leading to sub-optimal resource allocation, increased packet loss, and degraded network performance, particularly in dense traffic scenarios.

Method used

A communication method that determines a congestion ratio for a communication channel, obtains resource requirements for each terminal, and configures individual congestion control tables based on the channel's congestion ratio and terminal-specific needs, utilizing infrastructure-assisted classification and federated learning to adapt to varying traffic patterns.

Benefits of technology

Enhances network efficiency, reduces congestion and packet loss, and improves quality of service by providing adaptive and scalable resource allocation tailored to individual terminal needs, especially in high-density scenarios like V2X systems.

Abstract

The invention relates to a communication method comprising: - determining a congestion ratio for a communication channel based on measured data; - obtaining, for each terminal in a set of terminals (312, 316, 324), a requirement (504) for radio resources related to the communication channel; and - determining, individually for each terminal in the set of terminals, a respective congestion control table (520) based on the determined congestion ratio of the communication channel and further based on the requirement of each respective terminal.
