LTE-Advanced 中CoMP调度算法的研究
首发时间:2012-11-15
摘要:综述文章:随着LTE技术的成熟和商用化,ITU(国际电信联盟)也为下一代移动通信的演进提出了IMT-Advanced的技术标准,也就是我们通常所说的4G。LTE-Advanced则是其中最被看好的技术之一,其中的一些技术标准甚至超过了4G中提出的最小需求。而随着LTE-Advanced的一些关键技术的提升,许多与之适应的算法,尤其是资源分配方面的算法,都面临着听声的需要以满足新技术的需求。本文通过介绍LTE中调度算法以及加入了CoMP关键技术之后的 LTE-A对这一调度算法的改进算法来对比说明新的调度算法能够很好的发挥CoMP的对小区性能的提升,在边缘用户性能改善方面也令人满意。

Research on LTE-Advanced CoMP Scheduling Algorithm
Abstract:With maturity and commercialization of LTE technology, the ITU (International Telecommunication Union) has been prepared for the next generation mobile communication technology standard-IMT-Advanced, which is called 4G. LTE-Advanced is a promising technology, wich even has beyond the minimum requirements in the 4G standard. With upgrade of the key technologies in LTE-Advanced, new algorithms are requred to adapt them, which in particular, the resource allocation algorithm. In this paper, the scheduling algorithm introduced in LTE and LTE-A CoMP arecompared. The result shows that the new scheduling algorithms can play CoMP enhancement on cell performance, and it can also make the edge user performance improvement people satisfaction.
