1. A power control method, applied in a vectoring crosstalk cancellation system, comprising:

  • acquiring, by a vectoring control entity, a power control factor Diik of an ith transmit end on a kth subcarrier, wherein the ith transmit end is one transceiver of M transceivers located at a central office end, 1≦

    k≦

    K, and K indicates a quantity of subcarriers; and

    sending the power control factor Diik to the ith transmit end, so that if it is determined that the power control factor Diik is less than a power gain factor gik, of a current transmit signal of the ith transmit end, on the kth subcarrier, the ith transmit end modifies the power gain factor gik of the current transmit signal, so that a modified power gain factor g′

    ik is less than or equal to the power control factor Diik.
