摘　　要：利用LTE网络的多点协作传输(Co MP)技术,提出了一种基于博弈论的基站自优化节能方法,应用该方法可在基站的控制单元增加1个节能模块,此模块可以通过X2接口交互小区簇内各小区信道信息,使得各小区同频子载波上的发射功率相互博弈,以减少干扰最终达到动态平衡,提高网络容量。通过实验室仿真测试表明,该技术能够在保证网络吞吐量的同时降低系统的能耗,为运营商构建绿色节能的LTE网络提供了参考。According to coordinated multiple points transmission （CoMP） technology of LTE network, a self-optimizing energy-saving method of base station based on game theory is proposed. The control unit of base station can be added one energy-saving module by using the proposed method. This module can interact channel information with the cells within the cell cluster by X2 interface, which makes the transmit power of the pilot sub-carrier game in order to reduce interference, ultimately to achieve dynamic balance and increase network capacity. The simulation results show that this technology can reduce system power consumption with network throughput guarantee, which provides a reference for operators to build green energy-saving LTE networks.
