摘要

三维蜂窝结构是将小蜂窝三维地部署在大蜂窝上,被认为是近年来适应快速增长的数据流量的有效蜂窝结构之一。在这种细胞结构中,小细胞间的干扰是主要问题之一。作为一种减轻小区间干扰的技术,我们提出了一种网络协调波束形成技术,其中小小区基站采用水平波束形成技术,通过网络协调来协调其波束。我们还利用计算机模拟阐明了该方法在考虑真实细胞结构的多细胞环境下的吞吐量性能。

Inter-cell interference coordination by horizontal beamforming for small cells in 3D cell structure
3D cell structure, where small cells are three-dimensionally deployed on macro cells, is considered as one of the effective cell structures to accommodate data traffic growing rapidly in recent years. In this cell structure, inter-cell interference among small cells is one of the major issues. As a technique for mitigating inter-cell interference among small cells, we propose a network coordinated beamforming where small-cell base stations, applying horizontal beamforming, coordinate their beams by network coordination. We also clarify the throughput performance of the proposed method under a multi-cell environment considering a realistic cell structure using computer simulation.
