1. A method for a first station (STA) to transmit a preamble in a wireless local area network (WLAN), the method comprising:

  • configuring a frame comprising a first part of the frame for a first type STA and a second part of the frame for a second type STA,wherein the first type STA is a legacy STA in view of the second type STA,wherein the first part of the frame comprises a STF (Short Training Field) for the first type STA and a LTF (Long Training Field) for the first type STA,wherein the second part of the frame comprises a STF for the second type STA and a LTF for the second type STA,wherein a first tone spacing between first tones in a frequency domain for the first part is M times larger than a second tone spacing between second tones in the frequency domain for the second part, the M being an inter greater than 1, andwherein one or more of the STF for the second type STA and the LTF for the second type STA is configured;

    by mapping each of components of a sequence for the one or more of the STF for the second type STA and the LTF for the second type STA in every N tones with an interval of N tones among the second tones in the frequency domain, andby setting a remainder of the second tones, to which the components of the sequence are not mapped, to zero, the N being an integer representable as power of 2; and

    transmitting the frame to a second STA.
