Abstract: Proposed are a method and apparatus for receiving a PPDU on which BCC interleaving has been performed in a Multi-RU in a wireless LAN system. Specifically, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a Multi-RU which is an aggregate of a first RU and a second RU. The data field is generated on the basis of a coded bit string included in a BCC interleaver block. The coded bit string is obtained by interleaving a data bit string on the basis of first and second parameters. The data bit string is interleaved as the data bit string is entered into the BCC interleaver block in rows on the basis of the first parameter and is read out in columns of the BCC interleaver block on the basis of the second parameter.

Abstract: Proposed are a method and apparatus for receiving a PPDU on the basis of control information related to a pilot tone in a wireless LAN system. Particularly, a reception STA receives a PPDU from a transmission STA. The reception STA acquires control information related to a tone plan and pilot tone by decoding the PPDU. The reception STA decodes a data field of the PPDU on the basis of the control information. If a bandwidth of the PPDU is 480 MHz, the tone plan is a 6×996 tone RU or 3×2020 tone RU. An index of a first pilot tone within the 6×996 tone RU or 3×2020 tone RU is ±{112, 246, 360, 494, 598, 732, 846, 980, 1136, 1270, 1384, 1518, 1622, 1756, 1870, 2004, 2160, 2294, 2408, 2542, 2646, 2780, 2894, 3028}.

Abstract: The present disclosure proposes a method and device for configuring a UL_LENGTH parameter in TRIGVECTOR parameters in a wireless LAN system. Specifically, a transmission STA transmits a trigger frame to a reception STA. The transmission STA acquires the TRIGVECTOR parameters. The transmission STA receives a TB PPDU on the basis of the trigger frame and the TRIGVECTOR parameters. The TRIGVECTOR parameters include the UL_LENGTH parameter. When the TB PPDU is an EHT TB PPDU, the UL_LENGTH parameter is set to a first value that is not a multiple of 3.

Abstract: A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for a broadband. The first STF sequence is a sequence of which a phase rotation is applied to a sequence in which a second STF sequence is repeated. The second STF sequence is an STF sequence for a 80 MHz band defined in an 802.11ax wireless LAN system. If the broadband is a 320 MHz band, the first SFT sequence is a sequence in which preset sequence M is repeated, and is defined to be the same 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)).

Abstract: A method and an apparatus for transmitting an EHT PPDU to a wireless LAN system are presented. Particularly, a transmission device generates an EHT PPDU, and transmits the EHT PPDU to a reception device through a 320 MHz band of which a partial band is punctured on the basis of an RF. A legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is determined on the basis of a first method and a second method. The first method is for acquiring an optimum PAPR in the L-LTF. The second method is for acquiring an optimum PAPR on the basis of a maximum transmission bandwidth supported by the RE. The first phase rotation value is acquired on the basis of a second phase rotation value and a third rotation value. The second phase rotation value is a phase rotation value which repeats a phase rotation value that is defined with respect to an 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value that is defined by 80 MHz band units in the 320 MHz band.
