SYSTEM AND METHOD FOR OFDMA TONE ALLOCATION IN NEXT GENERATION WI-FI NETWORKS

SYSTEM AND METHOD FOR OFDMA TONE ALLOCATION IN NEXT GENERATION WI-FI NETWORKS

An orthogonal frequency division multiple access (OFDMA) symbol tone allocation includes a 256 tone payload consisting of 228 data and pilot tones and 28 null tones. The 28 null tones consist of guard tones and at least one direct current (DC) tone. In one example, the 256 tone payload consists of 2...

Zusammenfassung:An orthogonal frequency division multiple access (OFDMA) symbol tone allocation includes a 256 tone payload consisting of 228 data and pilot tones and 28 null tones. The 28 null tones consist of guard 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 symbol may be a downlink OFDMA symbol or an uplink OFDMA symbol.
