Abstract
A method is described for generating and transmitting a frame by a station. The method includes determining a bandwidth of a frame to be transmitted by the station; generating a long training field for the frame, wherein the long training field includes a set of pilot tones located at a set of subcarrier positions, wherein when the bandwidth of the frame is 10 MHz, the set of subcarrier positions include four subcarrier positions and the four subcarrier positions are set as {−21-α1,−7-α2,7+α3,21+α4} where α1, α2, α3, and α4 are odd values, and wherein when the bandwidth of the frame is 20 MHz, the set of subcarrier positions include six sub carrier positions, including {−53-β1,−25-β2,−11-β3, 11+β4,25+β5,53+β6} where β1, β2, β3, β4, β5, and β6 are odd values.
