1. A wireless communication device comprising:
a communication interface; and
processing circuitry that is coupled to the communication interface and that is configured to:
receive, via a plurality of sub-carriers and via the communication interface, a first orthogonal frequency division multiple access (OFDMA) frame from a first other wireless communication device, wherein the first OFDMA frame specifies a first subset of the plurality of sub-carriers for use by the wireless communication device and a second subset of the plurality of sub-carriers for use by a second other wireless communication device and a time during which the wireless communication device and the second other wireless communication device to make simultaneous transmission to the first other wireless communication device within a second OFDMA frame; and
transmit, during the time specified in the first OFDMA frame and via the communication interface, first data of the second OFDMA frame via the first subset of the plurality of sub-carriers to the first other wireless communication device when the second other wireless communication device simultaneously transmits second data of the second OFDMA frame via the second subset of the plurality of sub-carriers to the first other wireless communication device.
