    Abstract: Presented are a method and a device for receiving a PPDU in a wireless LAN system. Particularly, a receiving STA receives a PPDU from a transmitting STA through a broadband, and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. The first phase rotation value is acquired on the basis of a first preamble puncturing pattern of the broadband. The first preamble puncturing pattern includes the pattern in which 40 MHz or 80 MHz band is punctured in the broadband, when the broadband is a 320 MHz band. The first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1].

    Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wideband 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 wideband. When the wideband is a 320 MHz band, the first STF sequence is a sequence including a M sequence and is defined as {M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M 0 −M 1 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M}*(1+j)/sqrt(2).

    Abstract: A transmission and reception PPDU according to the present specification may include a first control signal field and a second control signal field. Overflowed information from the first control signal field may include a first encoding block of a common field of the second control signal field. In addition, the common field of the second control signal field may include various numbers of encoding blocks and various numbers of RU allocation subfields on the basis of the characteristics of the transmission and reception PPDU. In addition, the overflowed information may be included in a plurality of content channels using various methods.

    Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband communication and decodes the PPDU. The PPDU is received on the basis of an OFDMA scheme. The PPDU includes a first signal field. The first signal field includes first information on a preamble puncturing pattern for each 80 MHz band in the broadband communication. The first information consists of a 4-bit bitmap for the 80 MHz band.
