摘要
据预测在LTE网络中将有超过80%的数据业务发生在室内,因此室内覆盖对LTE通信网来说很重要。家庭基站是近年来新兴的室内覆盖技术。针对引入家庭基站的TD-LTE系统,文中分析了其存在的干扰场景,之后针对各种干扰场景给出相应的干扰管理策略,并详细介绍了3GPP R10中开发的毫微微小区(femtocell)增强型小区间干扰协调(eICIC,enhanced Inter-Cell Interference Coordination)技术,最后给出今后的研究方向。
It is predicted that more than 80% data service is happened indoor in the LTE network,so indoor coverage is very important for the LTE network.The home eNodeB is a new indoor coverage technology in recent years.For the use of Home eNodeB in TD-LTE network,this paper first analyzes the existence of interference scenarios,gives the corresponding interference management strategy for each scenario,then describes in detail the femtocell eICIC technology developed by 3GPP Release 10.Finally some suggestions are proposed for future research.
