PHY PAYLOAD OVER MULTIPLE TONE MASKS USING SINGLE TONE MASK PHY HEADER INFORMATION

摘要

A method of communications includes compiling a data frame for physical layer (PHY) by a first communications device at a first communications node on a network. The data frame includes a single tone PHY header portion and a data payload portion in a set of tones including at least one tone having a frequency different from a frequency of the single tone. The PHY header portion includes tone mask identification information identifying the set of tones. The first communications device transmits the data frame over the powerline to a second communications device at a second communications node on the powerline. The second communications device receives the data frame, and decodes the data payload using the tone mask identification information in the PHY header portion.
