1. A method comprising:

  • categorizing a plurality of cable modems in a cable network into interference groups;

    scheduling, by a cable modem termination system (CMTS) in the cable network, upstream transmissions and downstream receptions for cable modems in each interference group, such that no cable modem of any one interference group transmits upstream in a frequency range simultaneously as another cable modem in the same interference group receives downstream in the frequency range, wherein downstream transmission frequency is interleaved across a downstream symbol spanning a frequency range of an orthogonal frequency division multiplex block, wherein upstream transmission frequency is interleaved across an upstream symbol, wherein the upstream symbol is aligned with the downstream symbol;

    generating scheduling information of the scheduling; and

    transmitting the scheduling information to the cable modems.
