摘要
蜂窝网络是未来5G的关键技术特征,该特征可以满足未来大数据量大与信号覆盖面广的需求。但是小蜂窝网络与邻居小蜂窝存在着较为严重的同频干扰。为了解决小区之间的同频干扰,必须采用有效的干扰协调技术。本文在半静态资源复用方案与软频率复用方案基础上,提出一种新的资源分配方案,在提高边缘用户通信质量的同时,使系统总吞吐量最大化。
Cellular network is the key technical feature of 5G in the future,which can meet the needs of large amount of data and wide signal coverage. However,there is a serious interference between the small cellular network and the neighbor cellular. In order to solve the interference between cellulars,it is necessary to use an effective interference coordination technology. Based on the semi-static resource reuse scheme and soft-frequency reuse scheme,this paper proposes a new resource allocation scheme,which can improve the quality of the edge user communication and satisfy the maximization of the total system.
