Abstract
Systems and methods for bidirectional communication are provided. In one embodiment, a bidirectional communication comprises a multipoint-to-point host unit and a plurality of remote units communicatively coupled to the multipoint-to-point host unit through an orthogonal frequency division multiplexing waveform. The multipoint-to-point host unit is configured to receive the orthogonal frequency division multiplexing waveform, the orthogonal frequency division multiplexing waveform comprising a plurality of tones transmitted by the plurality of remote units. The multipoint-to-point host unit is configured to allocate up to a plurality of the plurality of tones to a first remote unit of the plurality of remote units based on a characteristic of upstream information transmitted by the first remote unit.
