An Investigation on Dynamic RAU Selection Method for Distributed Radio Mobile Communications System
分布式无线移动通信系统中远端天线单元动态选择方法研究

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.
