Fifth-generation wireless communication (5G) technologies not only fulfill the requirement of 1000 times increase of Internet traffic in the next decade but also offer the underlying technologies to the entire industry and ecology for the Internet of everything. Compared with the existing mobile communication technologies, 5G technologies are more widely applicable and have more complicated corresponding system design. In order to better balance the complexity and performance, artificial intelligence (AI) technologies have been considered for 5G. Typical and potential research directions to which AI can make promising contributions need to be identified, evaluated, and investigated. To this end, this overview paper first combs through several promising research directions of AI for 5G, based on the understanding of the key aspects of 5G technologies. Furthermore, the paper devotes itself in providing design paradigms including 5G network optimization, optimal resource allocation, 5G physical layer unified acceleration, and end-to-end physical layer joint optimization.
