1. A method in a wireless local area network (WLAN) system, the method performed by a first station (STA) in an Orthogonal Frequency Division Multiplexing (OFDM) mode and comprising:
- generating an Enhanced Directional Multi Gigabit (EDMG) Short Training Field (EDMG STF) signal a STF sequence,wherein the STF sequence includes an A sequence and a B sequence; and
transmitting an EDMG Physical Protocol Data Unit (PPDU) including the generated EDMG STF signal via a wireless channel based on one or more space-time streams (STSs) to the second STA,wherein the A sequence and the B sequence are determined based on a number of contiguous 2.16 GHz channels for the wireless channel and an index value of the one or more STSs, andwherein the STF sequence is defined as {A, 0, 0, 0, B}.

Abstract
The present specification discloses a method for transmitting and receiving a signal in a WLAN system, by a station, and a device therefor. More particularly, the present specification discloses, when a station transmits and receives a signal through a channel on which one or two channels are bonded, a method for constituting an enhanced directional multi gigabit (EDMG) short training field (STF) for an orthogonal frequency division multiplexing (OFDM) packet, and transmitting and receiving a signal comprising the constituted EDMG STF field, and a device therefor.

14. A first station (STA) in an Orthogonal Frequency Division Multiplexing (OFDM) mode in a wireless LAN (WLAN) system, the first STA comprising:
-
a transceiver having one or more RF (radio frequency) chains and configured to transmit or receive a signal to or from a second STA; and a processor connected to the transceiver and processing the signal transmitted or received to or from the second STA, wherein the processor is configured; to generate an Enhanced Directional Multi Gigabit Short Training Field (EDMG STF) signal based on a STF sequence, wherein the STF sequence includes an A sequence and a B sequence, and to transmit an EDMG Physical Protocol Data Unit (PPDU) including the generated EDMG STF signal via an wireless channel based on one or more space-time streams (STSs) to a second STA, wherein the A sequence and the B sequence are determined based on a number of contiguous 2.16 GHz channels for the wireless channel and an index value of the one or more STSs, and wherein the STF sequence is defined as {A, 0, 0, 0, B}.
