Abstract

本发明公开了一种功率控制方法及装置、系统，通过矢量化控制实体获取第i个发送端在第k个子载波上的功率控制因子Dii k,所述第i个发送端为位于中心局端的M个收发器中的一个收发器，1≤k≤K,K表示子载波的个数；将所述功率控制因子Dii k发送给所述第i个发送端；以使所述第i个发送端所述功率控制因子Dii k，若确定所述功率控制因子Dii k小于所述第i个发送端当前发送信号在所述第k个子载波上的功率增益因子gi k，则修改所述当前发送信号的功率增益因子gi k，使得修改后的功率增益因子gi ’k小于等于所述功率控制因子Dii k能够解决现有的功率控制方法中存在的控制复杂、降低整体线路的信号传输性能的问题。
