System and method for ofdma tone allocation in next generation wi-fi networks

An orthogonal frequency division multiple access (OFDMA) frame tone allocation includes a 256-tone payload consisting of 228 pilot and data tones and 28 null tones. The 28 null tones consist of protection tones and at least one direct current (DC) tone. In one example, the 256-tone payload consists of 224 data tones, 4 common pilot tones, and 28 null tones. In another example, the 256-tone payload consists of 222 data tones, 6 common pilot tones, and 28 null tones. In yet another example, the 256-tone payload may consist of 220 data tones, 8 common pilot tones, and 28 null tones. The OFDMA frame may be a downlink OFDMA frame or an uplink OFDMA frame. </p> <p>(Automatic translation with Google Translate, without legal value)
