Patent ID: 10862637

Abstract:
In accordance with embodiments, methods and systems for data transmissions are disclosed. A station (STA) transmits an orthogonal frequency division multiplexing (OFDM) frame to an access point (AP). The OFDM frame comprises an OFDM symbol. The OFDM symbol comprises data tones and pilot tones. The total number of the data tones and the pilot tones in the OFDM symbol is divisible by 4. In some embodiments, the OFDM symbol may comprises 232 data tones, 8 pilot tones, 5 direct current (DC) tones, and 11 edge tones. The 232 data tones and 8 pilot tones of the OFDM symbol may be segmented to a set of 15 blocks for channel estimation between the AP and the STA.
