Abstract
A method and a device for receiving a PPDU in a wireless LAN system are presented. Particularly, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The broadband is the 320 MHz band or 160+160 MHz band. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the broadband. The first STF sequence is the sequence in which phase rotation is applied to the sequence in which a second STF sequence is repeated. The second STF sequence is the STF sequence for the 160 MHz band defined in the 802.11ax wireless LAN system. The first sequence is the sequence in which a preset M sequence is repeated, and is defined as {M1−M0−M1−M0−M−1M0−M1−M0−M−1M0M−1M0M1−M0M−1M}*(1+j)/sqrt(2).
