AI 中文摘要
6G无线接入网（RAN）架构是5G RAN的有序演进。5G基线引入了模块化基站，为多样部署场景和多供应商互操作性提供了灵活框架。6G RAN的关键架构挑战是在使RAN适应新部署和服务需求的同时保留这些优势。本文回顾了新兴的3GPP 6G RAN架构，重点是边界选择。讨论了中央单元和分布式单元拆分增强、将无线单元识别为独立逻辑单元以及RAN-核心网络接口研究，其中对于连接服务，点对点信令优于基于服务的接口。还强调了开放领域，包括用于非连接服务 的RAN-核心网络接口、数据收集框架以及6G RAN的人工智能。
英文摘要
The 6G radio access network (RAN) architecture is emerging as a disciplined evolution of 5G RAN. The 5G baseline introduced modular base station, providing a flexible framework for diverse deployment scenarios and multi-vendor interoperability. The key architectural challenge for 6G RAN is to preserve these benefits while adapting the RAN to new deployment and service requirements. This article reviews the emerging 3GPP 6G RAN architecture with emphasis on boundary selection. It discusses central unit and distributed unit split enhancements, recognition of radio unit as a distinct logical unit, and the RAN-core network interface study, where point-to-point signaling is favored over service-based interface for connectivity services. It also highlights open areas including RAN-core network interface for non-connectivity services, data collection framework, and artificial intelligence for 6G RAN.
