Abstract: A tone map includes physical layer transmission properties for a multi-carrier communications channel. The physical layer transmission properties indicate modulation mode and transmission power to be used on one or more frequencies (i.e. “tones”). The transmission power may be reduced on a first frequency having a high signal-to-noise ratio (SNR) so that performance will improve for a second frequency having a lower SNR. Transmission power may be reduced on a first frequency having an unusably low SNR so that performance will improve on a second frequency. A tone map message is used to efficiently communicate modulation and transmission power adjustments on a per-carrier basis.
