Abstract
The present invention discloses a power control method, apparatus, and system. A vectoring control entity acquires a power control factor Dof an itransmit end on a ksubcarrier, where the itransmit end is one transceiver of M transceivers located at a central office end, 1≤k≤K, and K indicates a quantity of subcarriers; and sends the power control factor Dto the itransmit end, so that if it is determined, according to the power control factor D, that the power control factor Dis less than a power gain factor g, of a current transmit signal of the itransmit end, on the ksubcarrier, the itransmit end modifies the power gain factor gof the current transmit signal, so that a modified power gain factor g'is less than or equal to the power control factor D.
