摘　　要：中继技术(Relay)作为LTE-Advanced系统的关键候选技术之一,能够有效地扩展网络的覆盖范围并提高系统容量。由于其具有拓扑灵活以及低成本的优点,可以减少网络的建设成本。对于大规模组网,在网络建设前期的网络规划中,手动布放Relay将会增加网络的部署成本。针对对此问题,文章提出了一种自动选择Relay站址的方案,在减少建设成本的同时,保证新引入的干扰在可承受范围之内,使之相对准确而有效地实现覆盖扩展以及容量的提升。Relay technology is one of the key technologies for Long Term Evolution Advanced project.The introduction of Relay can effectively expand network coverage and higher capacity to the system.For large-scale network,in the early network planning of the network construction,manual laying Relay will increase the cost of network deployment.This article proposes a plan for automatic selection of Relay station,which can not only reduce construction costs but also ensure the introduction of the new interference in an affordable range.And this plan can help with relatively accurate and effective implementation of coverage expansion and capacity increase.
