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.

Abstract: A power spectral density (PSD) shape may be modified based upon the transmitter power setting of a transmitter. The power associated with notched frequencies and adjacent frequencies may be adjusted responsive to a change in transmitter power setting. As a result of adjusting the power for the notched frequencies and adjacent frequencies when operating at the different transmitter power setting, the performance of the transmission system is improved. The PSD shape may be considered dynamic, being modified responsive to a change in transmitter power setting by adjusting power associated with notches in the PSD shape based on the transmitter power setting and PSD constraint.

Abstract: A transmitting device may determine a physical layer transmission properties based upon an amount of data to transmit via a communications channel. The physical layer transmission properties may comprise a derated tone map that has a lower physical layer transmission throughput capability than an original tone map. An indication regarding the derated tone map may be included in a first message, a portion of a physical layer framing protocol, a physical layer control transmission (such as a frame control symbol), or other transmissions such that the receiving device can derive the derated tone map without significant added overhead.

Abstract: A method includes determining a first Signal-to-Noise Ratio (SNR) average for a first symbol set of at least one or more first symbols in one or more packets. The method includes determining a second SNR average for a second symbol set of at least one or more second symbols in the one or more packets.
