The present invention relates to a method and an apparatus for communication through a power line. The apparatus comprises: a sending module used for continuously sending pilot signals that are provided with preset levels on each of multiple carrier frequency bands of the power line, wherein the multiple carrier frequency bands are discrete from each other, for example, separated by occupied carrier frequency bands; and a transmission module used for sending data, such as data of a same user, on each of the multiple carrier frequency bands. The method and the apparatus can be used to ensure a communication quality requirement of a communication device. |
