A method for a station (STA) apparatus transmitting a physical protocol data unit (PPDU) in a wireless LAN (WLAN) system, according to one embodiment of the present invention, comprises: generating a high-efficiency-short training field (HE-STF) sequence; generating a PPDU including an HE-STF field configured based on the HE-STF sequence; and transmitting the PPDU, wherein the HE-STF field included in the PPDU is transmitted through a channel, and wherein the HE-STF sequence can be configured based on an M sequence comprising {-1, -1, -1, 1, 1, 1, -1, 1, 1, 1, -1, 1, 1, -1, 1}*(√1/2)(1+j). |
