摘要
Bunched系统由多个远端天线单元(RAU)和一个中心单元(CU)构成,可以有效地提高WiMAX等未来宽带无线网络的频谱利用率,能很好地解决热点地区覆盖问题。介绍了Bunched系统的结构,描述了其系统的特点和优点,分析了需要解决的关键技术。
Bunched system is consisted of several remote antenna units and a functional entity named central unit. It can improve the spectral efficiency in future broadband wireless network, and is well suited for hotspot applications. This paper first discusses the architecture of Bunched system and then explains the characters of Bunched system and key issues in it.
