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.
