1. A wireless communication device comprising:

  • a processor configured to generate a multi-user super-frame (MU-SF) to indicate a contention free period associated with a first at least one cluster and a contention based period associated with a second at least one cluster that includes at least one other cluster that is different than the first at least one cluster to govern communication medium access by a plurality of wireless communication devices that is located remotely from the wireless communication device; and

    at least one wireless communication interface configured to transmit the MU-SF to and support subsequent communications with the plurality of wireless communication devices based on the MU-SF, wherein at least one of;

    based on the first at least one cluster, the wireless communication device is further configured to receive a first signal from a first of the plurality of wireless communication devices using a first mapping of orthogonal frequency division multiplexing (OFDM) tones within a first at least one channel within a first at least one frequency band to receive a second signal from a second of the plurality of wireless communication devices using a second mapping of OFDM tones within a second at least one channel within a second at least one frequency band;

    orthe processor is further configured to generate at least one additional MU-SF based on communications received from at least some of the plurality of wireless communication devices during a time period governed by the MU-SF, the at least one wireless communication interface is further configured to transmit the at least one additional MU-SF to and support subsequent communications with the plurality of wireless communication devices based on the at least one additional MU-SF.
