摘要
目前我国4G网络正由广覆盖向深度覆盖推进,相应的基站站址密度越来越高,同时也出现了站点重叠覆盖区域网络性能发生掉坑的现象。目前业界普遍推崇Cloud BBU(CRAN)的无线接入网方案来降低站间干扰,改善边缘用户体验,实现资源利用率最大化。本文就Cloud BBU的关键技术——Co MP的实现原理、协议流程进行分析,并对Cloud BBU的适用场景进行了探讨。
At present, domestic 4 G networks are developing from broad coverage towards deep coverage. The density of base station site is higher and higher. It leads to the network performance deterioration in site overlapping areas. Currently, the radio access solution of Cloud BBU（CRAN） is honored by the industry to decrease the intersite interference, improve cell-edge user＇s experience and maximize resource utilization. In this paper, the implementation principle and protocol flow of Co MP, which is the key technique of Cloud BBU, are elaborated, and then the application scenario of Cloud BBU is discussed.
