Abstract: A method includes generating a data packet at an access point. The data packet is to be communicated using a waveform that includes a first set of tones that is allocated to a first destination device and a second set of tones that is allocated to a second destination device. The first set of tones is non-overlapping with respect to the second set of tones, and each tone of the first set of tones and each tone of the second set of tones is an orthogonal frequency-division multiple access (OFDMA) tone. The method also includes transmitting the data packet to the first destination device via an institute of electrical and electronics engineers (IEEE) 802.11 wireless network and transmitting the data packet to the second destination device via the IEEE 802.11 wireless network.
