内生AI技术可实现无线接入网(Radio Access Network, RAN)资源的动态优化、自主管理与智能化决策。与传统RAN及开放无线接入网(Open RAN)相比，AI RAN在提升网络灵活性、降低能耗和增强运营效率方面优势显著。从无线网络的演进技术入手，探讨基于云化和智能化演进的需求和趋势。基于智能化需求分析AI RAN的3个场景，结合Open RAN联盟(Open RAN alliance, O-RAN)架构的优缺点，探讨无线网络智能化的潜在解决方案。围绕AI RAN的关键技术，深入分析其在当前发展阶段的技术机遇与挑战，为6G智能化无线网络的发展提供理论支持与实践参考。
Abstract：AI-native technology optimizes communication and computation resources, enables autonomous management, and supports real-time intelligent decision-making in Radio Access Network(RAN). AI RAN enhances network flexibility, reduces energy consumption, and improves operational efficiency. These advantages make AI RAN a key potential technology for 6G networks. This paper begins by reviewing the evolution of wireless networks, focusing on requirements and trends in cloud-based and intelligent architectures. It then analyzes three AI RAN scenarios: AI for RAN, AI and RAN, and AI on RAN. The paper also evaluates the strengths and limitations of Open RAN alliance(O-RAN) architecture and explores potential solutions for intelligent wireless networks. Finally, it discusses key technologies of AI RAN, identifying current opportunities and challenges. The findings offer valuable insights for the development of 6G intelligent wireless networks.
