摘要:将单小区划分成为更高数量更小的扇区单元,是一种提升小区网络系统容量的高效方法之一。理想情况下,得益于空间复用技术,小区容量增益和小区的扇区数量成正比。但是前人的研究工作并没有考虑到小区用户分布的动态变化因素以及扇区天线数量分配方案。本文在集中式大规模天线技术、三维波束成形技术、智能天线技术的基础上,提出了一种基于小区用户需求分布的动态的三维扇区划分方案,并且针对动态的对扇区数量进行有效的天线资源配置。最后仿真结果显示,文中提出的方案提升了系统容量和吞吐量。

Antenna resource allocation and dynamic sector construction method based on centralized massive MIMO technology
Abstract:Dividing the single cell into a higher number of smaller sector units is an effective way to enhance the network capacity of the cell. Ideally, thanks to the spatial multiplexing technique, the cell capacity gain is proportional to the number of sectors in the cell. However, the previous research did not take into account the dynamic changes of cell user distribution and the number of sector antenna allocation scheme. In this paper, based on the centralized large-scale antenna technology, three-dimensional beam-forming technology, smart antenna technology, a dynamic three-dimensional sector division scheme based on the user's demand distribution is proposed, and for the effective number of sectors Antenna resource configuration. Finally, the simulation results show that the proposed scheme enhances the system capacity and reduces the system energy consumption.
Keywords: Information and communication systems Massive MIMO, antenna resources allocation, sectorization, beamforming
