摘要

在通信非高峰期，关闭未充分利用的基站是一种减小能耗的有效方法，睡眠基站内用户由邻近基站协作服务，避免了因小区范围拓展导致的基站发射功率消耗。考虑将基站睡眠技术与CoMP（coordinated multipoint，协作多点）传输技术相结合来提升系统性能，全面考虑协作过程中的功耗情况，提出一种基于功耗最小化的动态分簇和基站睡眠方案。该方案能够在为每个用户选择最佳分簇，满足QoS需求的同时，最小化系统功耗。仿真结果表明，本方案在提升能效方面优于传统基站睡眠方案。

Abstract

Shut down underutilized base station is a promising approach to reduce energy consumption of network during its off-peak time. The users in sleeping cell were served by neighboring cells，thus avoiding base station transmit power consumption caused by cell range expansion. Base station sleeping technique was combined with CoMP transmission to improve system performance，fully considered power consumption in the cooperative processing，and a scheme of dynamic clustering and base station sleeping to minimize power consumption was proposed. This scheme could select the best cluster to meet each user’s QoS requirement and minimize system power consumption. Simulation results show that the proposed scheme is better than traditional base station sleeping scheme in improving energy efficiency.
