6G OFDM-RIS Optimization Survey: Foundation Models and Deep Learning Emerge

A new survey paper explores optimization algorithms for joint Orthogonal Frequency-Division Multiplexing (OFDM) and Reconfigurable Intelligent Surface (RIS) configuration in 6G networks. It categorizes existing research into four paradigms: model-based convex relaxation, heuristic search, deep reinforcement and unsupervised learning, and emerging methods like foundation models and generative AI. The paper highlights that machine learning-based methods offer significant speedups in inference time compared to traditional solvers, though direct comparisons are difficult due to a lack of standardized benchmarks.
