摘要
第5代移动通信(5G)技术将为移动互联网的快速发展提供无所不在的基础性业务能力,在满足未来10年移动互联网流量增加1000倍发展需求的同时,为全行业、全生态提供万物互联的基础网络技术.相对已有的移动通信技术, 5G技术适用面更为广泛,系统设计也更为复杂.重新复兴的人工智能(AI)技术为5G系统的设计与优化提供了一种超越传统理念与性能的可能性.本文在概述5G移动通信关键技术的基础上,梳理了AI技术在5G系统设计与优化方面富有发展前景的若干发展方向,并给出了有关5G网络优化、资源最优分配、5G物理层统一加速运算以及端到端物理层联合优化等若干典型范例.
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.
