Abstract: A method and an apparatus for coordinating multiple power line networks are provided. The method includes: obtaining, by a central coordinator of a first power line network of multiple power line networks, signaling timeslot information of a second power line network; and determining, according to the signaling timeslot information, whether a predetermined signaling timeslot of the first power line network conflicts with a signaling timeslot of the second power line network, and if the predetermined signaling timeslot conflicts with the signaling timeslot of the second power line network, determining, according to a predetermined backoff rule, a contention-free timeslot as a signaling timeslot of the first power line network. Signaling timeslots of different networks can be staggered as sequential as possible, which ensures non-confliction of the signaling timeslots, thereby avoiding signal interference and attenuation in a shared network.
