摘　　要：在蜂窝系统中,采用基站休眠策略时,如果固定设置工作基站功率,将导致基站低负载时,网络功率效率降低。提出基于基站休眠的负载合并动态功率控制算法,低负载的宏基站进入休眠,负载较高的宏基站为工作基站,工作基站根据本小区及其分担的邻近休眠基站内的负载变化,动态调节自身的功率。仿真结果表明,所提出的动态功率控制算法在满足用户服务质量的前提下,有效降低了整个蜂窝网络的功率消耗。With base-station sleeping strategy in a cellular system,the fixed setting of base-station power would reduce network power efficiency when base station being in low load. A load merge dynamic power control algorithm based on base station sleeping strategy is proposed,and when low load Me NB is switched to sleeping-mode,heavy load Me NB acts as working base-station. Working base-station dynamically adjusts the transmit power in accordance with the load fluctuations of its own cell and the contributory neighboring sleeping-mode base-station. Simulation results show that the proposed dynamic power control algorithm could effectively reduce the power consumption of the entire cellular network with satisfaction of the user’s Qo S guarantees.
