Abstract
Disclosed are a method and device for transmitting or receiving an STF for a new numerology in a wireless LAN system. A method performed by a first station (STA) in a wireless LAN system according to an embodiment disclosed herein may comprise the steps of: generating a physical layer protocol data unit (PPDU) including a non-legacy short training field (STF); and transmitting the generated PPDU to one or more second STAs. In the non-legacy STF field, a specific STF sequence may be applied for each transmission bandwidth of a PPDU type supporting the new numerology.
