Abstract
Disclosed is a method for transmitting a preamble in a wireless communication system, particularly, a wireless LAN system, and a station device for performing the same. To this end, a station for transmitting a preamble configures a wireless frame including a first type terminal frame portion, which has first length in a time domain, and a second type terminal frame portion, which has a second length corresponding to a length that is an integer times the first length. The first type terminal frame portion includes a first type terminal preamble including a first type terminal short training field (STF) and a first type terminal long training field (LTF), and the second type terminal frame portion includes a second type terminal preamble including a second type terminal SFT and a second type terminal LTF. Here, the station configures the second type terminal preamble by allocating sequence components at an interval of an integer number of tones in a frequency domain and transmits the configured wireless frame to another station.

14. 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 (L-STF) and a LTF (Long Training Field) for the first type STA (L-LTF), wherein the second part of the frame comprises a STF for the second type STA (HE-STF) and a LTF for the second type STA (HE-LTF), and wherein one or more of the HE-STF and the HE-LTF is configured by mapping each of components of a sequence in every N tones in a frequency domain, the N being an integer representable as power of 2; and transmitting the frame to a second STA. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A station (STA) configured to transmit a preamble in a wireless local area network (WLAN), the STA comprising:
-
a processor for 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 (L-STF) and a LTF (Long Training Field) for the first type STA (L-LTF), wherein the second part of the frame comprises a STF for the second type STA (HE-STF) and a LTF for the second type STA (HE-LTF), and wherein one or more of the HE-STF and the HE-LTF is configured by mapping each of components of a sequence in every N tones in a frequency domain, the N being an integer representable as power of 2; and a transceiver for transmitting the frame to a second STA. - View Dependent Claims (22, 23, 24, 25, 26, 27)
