Abstract: Proposed are a method and a device for configuring a spatial reuse field in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB PPDU to the transmission STA through a pre-configured frequency band. The trigger frame comprises a common information field and a special user information field. The common information field comprises first to fourth spatial reuse fields. The special user information field comprises fifth and sixth spatial reuse fields. When the pre-configured frequency band is a 20 MHz band, the first to fourth spatial reuse fields are configured by the value of the fifth spatial reuse field.

Abstract: Proposed is a method and device for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband and decodes the PPDU. 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 obtained on the basis of a first preamble puncturing pattern of the broadband. When the broadband is a 320 MHz band, the first preamble puncturing pattern includes a pattern in which a 40 MHz or 80 MHz band is punctured in the broadband. The first STF sequence is a sequence including an M sequence and is defined as {M 1 −M 0 −M 1 −M 0 M 1 −M 0 −M 1 −M 0 −M −1 M 0 M −1 M 0 −M −1 M 0 M −1 M}*(1+j)/sqrt(2).
