最近，异构网络（HetNets）的概念被提出，作为蜂窝网络提供更高覆盖率和容量的替代解决方案。在HetNets概念中，许多小型基站（SBSs）被应用于现有的宏基站（mbs）小区，以增加覆盖范围和系统容量。然而，在现有的宏蜂窝中使用许多SBSs会导致功耗增加，同时降低下行蜂窝网络的能量效率。为了解决这一问题，本文提出了一种基于小区吞吐量的HetNets中sbs的睡眠控制方案。在该方案中，以sbb的单元容量比作为决策标准，使sbb进入休眠状态。从各种仿真结果来看，该方案比传统方案具有更高的能效和系统吞吐量。
Recently, the concept of heterogeneous networks (HetNets) has been proposed as an alternative solution to provide higher coverage and capacity for cellular networks. In HetNets concept, many of small base stations (SBSs) are employed in the existing cell of macro base stations (MBSs) to increase the coverage and system capacity. However, the employment of many SBSs in the existing macro cells would causes the increase in power consumption with decreasing the energy efficiency in downlink cellular networks. To solve this problem, this paper proposes a cell throughput based sleep control scheme for the SBSs in HetNets. In the proposed scheme, the cell capacity ratio for the SBSs is employed as decision criteria to put the SBSs into sleep state. From various simulation results, the proposed scheme can achieve better energy efficiency and better system throughput than the conventional schemes.
