Abstract: This application provides a power line communication method. Wherein, a first node determines a channel status of a channel between a second node and the first node in an alternating current cycle. Then, the first node may divide the alternating current cycle into time windows based on the channel status, and determine modulation coding parameters used for data transmission between the second node and the first node in the time window obtained through division. Further, the first node may send information about the time window obtained through division and the modulation coding parameters used in the time window obtained through division to the second node.
