SYSTEM AND METHOD FOR COMMUNICATING AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXED FRAME FORMAT
FIG8 illustrates embodiment tone plans for a 40 MHz OFDMA frame
FIG8 illustrates tone plans 850 for a 40 MHz transmission for OFDMA and SU frames. There are 484 tones for data, pilot, and leftover tones, and 28 tones for DC and edge tones. Tone plans 850 includes the OFDMA tone plan 870 and the SU tone plan 872. The tones in the OFDMA tone plan 870 are sent to or received from multiple STAs. The tones in the SU tone plan 872 are sent to or received from a single STA.

['1. A method implementing orthogonal frequency division multiple access, OFDMA, communication according to Institute of Electrical and Electronics Engineers, IEEE, 802.11 ax standard comprising: transmitting or receiving a downlink or uplink frame; wherein the IEEE 802.1lax standard adopts one or more tone plans, each of which comprises a first set of data and pilot tones, a second set of data and pilot tones, and a direct current,DC, region positioned between the first set of data and pilot tones and the second set of data and pilot tones, wherein the DC region consists of five DC tones; and, the tone plan further comprises a first edge region, and a second edge region, the first set of data and pilot tones positioned between the first edge region and the DC region, and second set of data and pilot tones positioned between the DC region and the second edge region, wherein the first edge region includes 12 guard tones and the second edge region include 11 guard tones; wherein the tone plan is a tone plan of 40MHz channel; and wherein the first set of data and pilot tones consists of nine 26-tone resource units, RUs, and the second set of data and pilot tones consists of nine 26-tone RUs; or the first set of data and pilot tones consists of one 242-tone RUs and the second set of data and pilot tones consists of one 242-tone RUs.']
