A method for transmitting a physical layer protocol data unit (PPDU) by a station (STA) in a wireless LAN (WLAN) system according to an embodiment of the present invention may comprise the steps of: configuring an L-part including a legacy-short training field (L-STF), a legacy-long training field (L-LTF), and a legacy-signal field (L-SIG); when a PPDU to be transmitted by the STA corresponds to apredetermined format, performing binary phase shift keying (BPSK) modulation on N consecutive symbols located after the L-SIG, for packet classification; and transmitting the PPDU including the L-part and the N BPSK-modulated symbols. 根据本发明的实施方式的一种由站(STA)在无线LAN(WLAN)系统中发送物理层协议数据单元(PPDU)的方法可以包括以下步骤：配置包括传统短训练字段(L-STF)、传统长训练字段(L-LTF)和传统信号字段(L-SIG)的L部分；当将由所述STA发送的PPDU是预定格式时，对用于分组分类的位于所述L-SIG之后的N个连续符号执行二进制相移键控(BPSK)调制；以及发送包括所述L部分和所述N个经BPSK调制的符号的所述PPDU。
