摘要

针对绿色通信中如何能在保证一定服务质量的前提下降低能量消耗这一关键问题，根据带宽交换能量的思想，综合考虑系统吞吐量和用户间公平性，提出了LTE 下行传输中基于负载的资源调度策略，通过降低频谱效率换得能量效率的提高，以达到节能的目的。仿真结果表明，所提的两个算法在满足用户速率要求的同时都能在很大程度上降低发射功率，且保证了用户间的公平性。

Abstract

The key question of green communication is how to reduce energy consumption while maintaining the quality of service. According to the conception of trading bandwidth for energy

with the addition of taking system throughput and fairness among users into consideration

a resource scheduling strategy based on system load conditions for LTE downlink was proposed to reduce energy consumption by improving energy efficiency at the cost of spectral efficiency. The simulation results show that the two algorithms can greatly reduce transmit power on the premise that the requirements of the user rate are met

and ensure the realization of the fairness among users.
