1. A method for an orthogonal frequency division multiplexing multipoint-to-point communications system, the method comprising:

  • establishing communication between a first remote unit of a plurality of remote units and a host unit, the plurality of remote units communicatively coupled to the host unit in a multipoint-to-point configuration;

    transmitting non-control data on up to a plurality of tones from the first remote unit using an orthogonal frequency division multiplexing (OFDM) waveform, the up to a plurality of tones modulated with the non-control data using a first modulation scheme; and

    transmitting control signals on up to a plurality of tones from the first remote unit using an orthogonal frequency division multiplexing (OFDM) waveform, the up to a plurality of tones modulated with the control signals using a second, more robust modulation scheme.
