摘　　要：为了适应下一代移动通信系统的宽带化的需求,现有3G技术已经不能满足宽带化的需求,3GPP开始了下一代移动通信系统LTE的研究,中国也开始了从TD-SCDMA到LTE TDD技术的演进。功率控制可以在不影响用户的通信质量的情况下尽可能的降低用户的发射功率,增加充电终端的使用时间。在研究LTE FDD上行功率控制算法的基础上,提出了一种改进的上行功率控制算法,并将此算法应用于TD-LTE系统中进行了仿真分析,仿真结果验证了此算法的正确性。For the existing 3G technology could not meet the broad-bard demand of the next-generation mobile communication system,3GPP starts the research on next-generation mobile communication system--LTE,and meanwhile China also begin the evolution from TD-SCDMA to LTE TDD.The power control could reduce the transmitting power as much as possible and raise the working time of the charging mobile phone without any influence on the quality of communication.Based on study of the uplink power control algorithm of LTE FDD,this paper gives an improved uplink power control algorithm.Simulation on this proposed algorithm applied in TD-LTE system indicates its feasibility and correctness.
