Abstract: Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. In detail, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a preamble and a data field. The first band includes first and second subblocks. The data field includes first data for the first subblock and second data for the second subblock. The first data is generated on the basis of data in which constellation mapping is performed on encoded data bits. The second data is generated on the basis of data obtaining by duplicating the first data and applying phase rotation thereto.

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).
