摘    要:在3GPPLTE—A网络中,可以使用CoMP(多点协作)技术来提高边缘用户的性能。为了最大化全网边缘用户的总吞吐量,关键是要确定在每个PRB(物理资源块)中同时被服务的用户集合、每个被调度用户所对应的协作基站、以及各基站的传输功率。基于每个边缘用户的RSRP(参考信号接收功率),提出一种低复杂度的集中式传输调度算法,针对每个PRB中被服务的边缘用户和相应的协作基站进行动态选择,并通过仿真实验验证算法的性能增益。

关 键 词:多点协作  集中式传输调度  调度

Abstract:In 3GPP LTE network, CoMP (Cooperative Multi-Point) is used to improve the performance of edge users. In order to maximize the total throughput of all-edge users in the network, it is critical to identify the set of edge user served at the same time in each PRB ( Physical Resource Block) and the set of cooperative base-stations for each scheduled user, as well as the transmission power of each base-station. Based on the RSRP (Reference Signal Receiving Power) of each edge user, a centralized transmission scheduling algorithm with low complexity is proposed, thus to dynamically choose the edge users and cooperative base-stations in each PRB. Finally the simulation indicates the performance gain of the proposed algorithm.
Keywords:CoMP  CTS  scheduling
