Abstract: Embodiments of this application provide a data transmission method applied to power line communication, and a power line communication apparatus and system. The data transmission method includes: a power line node generates a data frame, where the data frame includes a first field, a second field, and a third field, the first field is used to carry a modulation parameter, the second field is used to carry, in a bit mapping manner, identification information that is of at least one destination node of current multicast and that is configured by the power line node, and the third field is used to carry service data; and the power line node sends the data frame to a node in a power line communication network. According to the data transmission method, data can be efficiently transmitted to a plurality of destination nodes to save bandwidth.
