摘　　要：无线接入网开放分为架构开放和能力开放,为应对5G高频段部署带来的室内覆盖及高成本问题,基于开放架构的5G有源小基站值得深入研究,同时基于开放架构有助于实现无线接入网的能力开放。首先介绍了符合开放架构的5G扩展型小基站的基本架构,然后分别从公众网络和虚拟专网两方面论述了5G扩展型小基站的两个不同应用场景,最后给出了面向室内场景建立统一计算环境的架构及展望。The openness of radio access network is divided into open architecture and open capabilities.In order to cope with indoor coverage and high cost caused by 5 G high-frequency deployment,5 G active small base stations based on the open architecture are worthy of in-depth research.At the same time,the open architecture helps to open the capabilities of the radio access network.Firstly,this paper introduces the basic architecture of 5 G extended small base stations with open architecture,and then two different application scenarios of 5 G extended small base stations are discussed in terms of public and private networks,respectively.Finally,the architecture and outlook of establishing a unifi ed computing environment are given for indoor scenarios.
