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 device may determine adapted physical layer transmission properties based upon characteristics of a packet stream to be transmitted via a communications channel. The physical layer transmission properties may comprise an adapted tone map that is associated with an aggressive physical layer throughput capability for UDP traffic, a conservative physical layer throughput capability for TCP traffic, or a dynamically adjusted physical layer throughput rate for mixed traffic. An indication regarding the adapted 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 adapted tone map without significant added overhead.
