摘要
为解决5G室内覆盖遇到的难点问题,分析了几种主流的5G室内分布系统方案,对其中的新型室分关键技术进行了深度分析,在此基础上结合几种压缩算法给出了BBU-PB、PB-PB、PB-p RRU各段链路的IQ位宽及相应性能,最后详细对比了各种方案的优缺点,包括5G DAS、新型室分、白盒小站等,对5G室内分布系统演进进行了展望。
To tackle the difficult issues encountered in 5G indoor coverage,this paper analyzes several mainstream 5G indoor distribution system solutions,and investigates the corresponding novel key technologies in depth.Furthermore,several compression algorithms provide the IQ bit width and the corresponding performance for BBU-PB,PB-PB,and PB-p RRU links.Finally,a comprehensive comparison is given in terms of the advantages and disadvantages of various solutions,including 5G DAS,new room division,white-box small stations,etc.,and the evolution of 5G indoor distribution systems is prospectively discussed.
