摘要

在异构蜂窝网络(HCNs)中，双连接(DC)可以提高用户的吞吐量。此外，基于协调多点(CoMP)的传输/接收可以在hcn中提供更高的覆盖和吞吐量，特别是对小区中的边缘用户。本文将数据中心的资源分配问题视为一个优化问题，并给出了基于时间调度程序的最优用户调度问题。我们比较了DC与HCN中CoMP的吞吐量和覆盖性能。此外，在不同的物理场景中，对不同的用户密度和小单元的数量进行了广泛的模拟结果。研究结果与蜂窝网络运营商在hcn中选择适当的技术高度相关。

Performance comparison of dual connectivity with CoMP in heterogeneous cellular networks

The dual connectivity (DC) can increase the users' throughput in heterogeneous cellular networks (HCNs). Additionally, the coordinated multi-point (CoMP) based transmission/reception can provide higher coverage and throughput in HCNs, specially to edge users in the cell. In this paper, we frame the resource allocation problem for DC as an optimization problem and present the optimal user scheduling for a time based scheduler. We compare the throughput and coverage performance of DC with respect to CoMP in a HCN. Further, extensive simulation results are presented for various user densities and number of small cells in diverse physical scenarios. The results are highly relevant for selection of appropriate technology in HCNs by cellular network operators.
