功率控制技术是移动通信系统中重要的技术.在LTE系统中设置下行链路中基站或上行链路中终端的发射功率来控制功率,通过功率控制来补偿各种慢衰落、控制小区间干扰、改善无线信道状况.目前LTE上行链路功率控制技术主要存在着两方面的问题,一是小区内功率控制补偿因子设置不灵活、二是小区间功率控制方案中缺乏对OI指示下的功率调整量灵活性的考虑.针对问题一本文介绍了基于补偿因子自适应的LTE小区内功率控制算法,该算法叫之FPC算法而言提高了小区的吞吐量,并且对干扰是可控的.针对问题二本文介绍了一种基于路径损耗差的OI指示下小区间功率控制算法,与传统的基于OI指示下的小区间功率控制算法相比,该算法在抑制小区间干扰和提高小区边缘用户方面优于传统算法.

Power control technology is the important technology of mobile communication system.Set down link in a LTE system base station in the terminal or the uplink transmission power to control the power,through the power control for all kinds of slow fading,control of interference between zones,improve wireless channel conditions.LTE uplink power control technology at present there are two main problems,one is power control compensation factor is set inside the village is not flexible,and second,the power control scheme between zones in the lack of OI indicates the power adjustment quantity flexibility under consideration.In view of the problem were introduced in this paper,based on a compensation factor inside the village of LTE adaptive power control algorithm,the algorithm is called the FPC algorithm in terms of throughput,improved village and is controllable to interference.For question 2 in this paper,a OI instructions based on path loss difference between community under the power control algorithm with the traditional minizone power control algorithm based on OI order compared to the algorithm in suppressing interference between zones is superior to the traditional algorithm and improve the cell edge users.
