1. A wireless communication device comprising:

  • a communication interface; and

    processing circuitry that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry configured to;

    generate a first orthogonal frequency division multiple access (OFDMA) frame that includes information that specifies a first time period during which a first other wireless communication device is to transmit first information via a first subset of OFDMA sub-carriers of a communication channel to the wireless communication device, wherein the first other wireless communication device has a first capability based on a first communication protocol;

    transmit the first OFDMA frame to the first other wireless communication device;

    receive the first information from the first other wireless communication device via the first subset of OFDMA sub-carriers of the communication channel during the first time period specified within the first OFDMA frame;

    generate a second OFDMA frame that includes information that specifies a second time period during which a second other wireless communication device is to transmit second information via a second subset of OFDMA sub-carriers of the communication channel to the wireless communication device and also during which a third other wireless communication device is to transmit third information via a third subset of OFDMA sub-carriers of the communication channel to the wireless communication device, wherein both the second other wireless communication device and the third other wireless communication device have a second capability based on a second communication protocol that is different than the first capability based on the first communication protocol;

    transmit the second OFDMA frame to the second other wireless communication device and the third other wireless communication device; and

    receive the second information from the second other wireless communication device via the second subset of OFDMA sub-carriers of the communication channel and the third information from the third other wireless communication device via the third subset of OFDMA sub-carriers of the communication channel via another OFDMA frame during the second time period specified within the second OFDMA frame.
