New VAE-EVT framework improves radio map prediction for URLLC

Researchers have developed a new physics-informed VAE-EVT framework to improve the prediction of low signal-to-noise ratio (SNR) regions crucial for ultra-reliable low-latency communication (URLLC). This model distinguishes between the bulk and tail distributions of SNR, using a Gaussian mixture model for the bulk and a generalized Pareto distribution for the tail. When evaluated on the RadioMapSeer dataset, the VAE-EVT framework achieved a significantly lower SNR RMSE of 4.83 dB in the critical 0.1% outage region, outperforming a GAN-based model which had an RMSE of 21.90 dB.
