•

ArXiv

Analysis

This paper addresses the challenge of dynamic Radio Environment Map (REM) generation for 6G Cellular Vehicle-to-Everything (C-V2X) communication. The core problem is the impact of physical layer (PHY) issues on transmitter vehicles due to the lack of high-fidelity REMs that can adapt to changing locations. The proposed Coordinate-Conditioned Denoising Diffusion Probabilistic Model (CCDDPM) offers a lightweight, generative approach to predict REMs based on limited historical data and transmitter vehicle coordinates. This is significant because it enables rapid and scenario-consistent REM generation, potentially improving the efficiency and reliability of 6G C-V2X communications by mitigating PHY issues.
