An Investigation on Dynamic RAU Selection Method for Distributed Radio Mobile Communications System

摘要

摘要: 分布式无线移动通信系统是由多个远端天线单元(RAU)通过有线或无线传输方式连接到基站组成的系统，其远端天线单元的选择方案将影响移动通信系统的性能。该文在分析移动通信系统容量、信号传输可靠性和系统传输业务质量(QoS)保障的基础上，研究动态选择RAU的基本准则，探讨分布式无线移动通信系统中RAU的动态选择方法，并在蜂窝小区场景和曼哈顿场景中对一种面向系统容量优化的动态选择RAU方法的系统容量分布和RAU数量的选择结果进行仿真, 仿真结果表明，采用此动态选择方法的系统具有较高的系统容量和平稳的小区容量分布。

Abstract: Distributed radio mobile communications system consists of Base Station (BS) and some Remote Antenna Units (RAUs) connecting with BS by wireline or wireless transmission. RAU selection scheme will influence the system performance. In this paper, RAU selection criteria are investigated based on the analysis of capacity, signal transmission reliability and QoS guarantee of mobile communications system. Dynamic RAU selection methods are explored for system performance optimization. The results of selected RAU number and system performance of a dynamic RAU selection method for system capacity optimization are studied by simulation work in cellular and Manhattan scenario. Simulation results show that the system with this dynamic RAU selection method has higher system capacity and stable capacity distribution.
