摘要

无线通信能耗问题受到越来越多重视，能量效率成为下一代无线通信（5G）三大效率特性之一。当前异构网络（heterogeneous network

HetNet）负载均衡的研究缺少对网络整体功耗的优化考量，根据异构网重叠覆盖的特性建立了面向指派模型的用户负载功率模型，并针对有限的用户负载问题提出一种扩增指派算法求解宏扇区内所有基站功率最小化问题，在LTE系统级仿真平台中仿真表明，无论基站是否支持休眠功能，此算法都能在保证用户速率的条件下有明显的节能效果。

Abstract

Energy consumption of wireless network is receiving more and more attention and has become one of key aspects of 5G while few researches on heterogeneous network （HetNet）load balancing focused in power consumption. User power model was built towards assignment model

based on which the augmented assign algorithm was proposed to minimize power of HetNet on condition of limited user data load. Simulation on system level platform show that power is effectively saved no matter base stations support sleep mode or not

meanwhile

ensure data rate of users.
