[摘要] 提出了一种面向未来移动通信的超蜂窝网络架构设计,其核心技术包括:超蜂窝无线组网技术、接入网虚拟小区技术和云平台支撑技术。超蜂窝无线组网技术的特点是空口控制与业务覆盖的分离,进而演进为对空口资源和流程的重构;接入网虚拟小区技术的特点是处理逻辑与空口覆盖的分离,进而演进为以用户为中心、结合SDN(Software-defined networking,软件定义网络)技术的接入网处理重构;云平台支撑技术的特点是接入网处理与计算资源的分离,进而演进为面向运营、平台化和虚拟化的计算重构。超蜂窝网络架构的设计与大规模天线阵、高频段大带宽通信的新兴物理层传输技术有很好的统一性,并且衍生出了一些新颖的跨层跨域的统一研究方法。

[Abstract] This paper describes hyper-cellular access network architecture (HCAN) for future mobile communication systems. Three base technologies are used: hyper-cellular architecture (HCA), collaborative access network (CAN), and access network supporting platform (CAN-Platform). HCA decouples control and traffic in the air interface and re-constructs air interface resource and process flow. CAN decouples process and air interface coverage and then reconstructs the RAN in a user-oriented, SDN-like way. CAN-Platform decouples process and computing and then then evolves into the operations-oriented, platform and virtualized computing reconstruction. HCAN is an integral design suitable for emerging PHY technologies, such as large-scale MIMO and high-spectrum wideband communication. With such integral design, an interesting cross-domain, cross-layer study framework can be built.
