摘　　要：对比5G小基站系统2种现阶段常用前传接口切分方式,确定了option 7-2切分方式在降低前传带宽的优势。随着天线数的增加,option 7-2切分方式对前传带宽的压力越小。通过前传接口承载信息设计、交互流程明确、接口模块拆分完成了option 7-2前传接口的设计方案,利用测试平台的搭建、实时数据的抓取分析进一步验证了5G前传接口方案的正确性和合理性。By comparing the two commonly used segmentation methods of the fronthaul interface in 5G small base station,the advantage of option 7-2 segmentation method in reducing the fronthaul bandwidth is determined.With the increase of the number of antennas,the pressure of option 7-2 segmentation method on the fronthaul bandwidth is smaller.The solution of option 7-2 fronthaul interface is completed through the information bearing design of the fronthaul interface,the clearing of interaction process and the splitting of interface module.Then,the correctness and rationality of the 5G fronthaul interface scheme is further verified by the construction of the test platformand the capture and analysis of the real-time data.
