摘要:

基于LTE有源天线外场测试结果,分析对比了在传统3×1网络拓扑以及垂直扇区化3×2网络拓扑两种场景下的单用户下行速率体验。结果表明,在给定的网络部署场景下内外小区间的同频干扰将会大大降低垂直扇区化功能对网络性能的增益。针对LTE有源天线垂直扇区化未来部署应用提出了3点建议,为业界后续LTE有源天线研究发展提供参考。

Abstract:

An evaluation of vertical sectorization in LTE field trial was conducted. The field trial results show that the performance of vertical sectorization will be decreased due to the co-frequency interference between the inner and outer cells. Furthermore, some practical suggestions on the deployment of vertical sectorization in LTE network were proposed.
