AI and communication is a key usage scenario envisaged for 6G. In contrast to 5G, where AI adoption has come only as an afterthought, 6G aims to embrace AI right from the beginning. AI-native RAN shifts the trend from fixed, one-size-fits-all algorithms to continuously adaptive, data-driven intelligence embedded throughout the RAN stack for site-specific optimizations. However, embedding AI for RAN introduces stringent latency constraints and computational challenges.
