一种动态分层小区结构的载干比性能分析

将自适应多波束天线与移动通信小区覆盖技术有机融合，提出了一种基于基站适应多波束天线的动态覆盖方案。这一文献将一个传统的小区群覆盖结构分两个区域进行覆盖，其中一个区域为固定覆盖，另一部分则利用基站自适应多波束天线在垂直面将覆盖区域分割动态圆形分层小区。这一覆盖方案的重要特点在于有助于改善频率复用下载干比性能及动态覆盖的冗余度。计算机模拟结果证实了这一方案的可行性。

CIR performance analysis of a dynamic multi-layer cellular configuration

According to the idea which the application of adaptive multi beam antennas in the mobile communication systems should be blended in well with cell configuration, a novel cell coverage strategy with synodical channel planning is proposed, in which the cluster cellular region are portioned into two region fixed coverage region with conservation reuse factor. And a dynamic coverage region with a more frequent reuse. And the dynamic coverage region is divided into circular multi layered zones by means of vertical splitting of radiation pattern of the multi beam base station antennas. A key performance factor is that the dynamic coverage region can improve the performance of carrier interference ratio and the flexibility of dynamic coverage range variation, which is illuminated by the numerical simulation results.
