Integrated AI and Communications: A Two-Way Catalysis Toward 6G and Beyond

Artificial intelligence (AI) and wireless communications are catalyzing each other's advancement as we approach 6G networks and beyond. This article presents a perspective on the two-way interplay between AI and communications—how AI techniques are revolutionizing communication network design (AI4Comm) and how emerging communication technologies are enabling and accelerating AI (Comm4AI). We discuss recent advances and outline the challenges in realizing an AI-native wireless ecosystem and propose a roadmap for integrating AI and communications, offering insights into a future where wireless communications and AI evolve together.
