摘要
为降低5G室内网络部署和运维成本,文章提出基于有源小基站的5G室内覆盖方案,采用三级架构的有源室分系统,能够提供室内全覆盖能力。文中对多种可能的基于不同前传接口方式的设计方案进行分析比较,具体包括接口容量、性能及实现方式。进一步地,为扩大5G有源小基站生态链,促进基带处理单元与射频处理单元之间的互通,降低整体部署成本,文中对前传接口Option7-2协议进行了详细阐述,为前传接口开放提供参考。
In order to reduce the cost of deployment and maintenance for 5G indoor network,an indoor network scheme based on active pico base station is proposed in this paper.The architecture of the equipment can be devided into 3 parts,including BBU,HUB and pRRU.In this paper,three schemes with different fronthaul interface options have been analyzed and compared as the aspects of interface capacity,performance and realization way.Furthermore,in order to promote the interoperability between BBU and pRRU,to reduce the overall deployment cost,the Option 7-2 protocol of fronthaul interface is elaborated in detail,which provides a reference for the opening of fronthaul interface.
