    摘要: Proposed are a method and an apparatus for receiving an EHT PPDU in a wireless LAN system. Specifically, a reception STA receives an EHT PPDU including an STF signal from a transmission STA through a 320 MHz band or a 160+160 MHz band. The reception STA decodes the EHT PPDU. The STF signal is generated on the basis of an EHT STF sequence for the 320 MHz band or the 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a preconfigured M sequence is repeated, 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}*(1+j)/sqrt(2).

    摘要: In a wireless local area network (LAN) system, a station (STA) generates an NGV PPDU, wherein the NGV PPDU comprises: a first legacy control field; a second legacy control field in which the first legacy control field is repeated; a first NGV control field; a second NGV control field in which the first NGV control field is repeated; an NGV-short training field (NGVSTF); and an NGV-long training field (NGV-LTF), and the first NGV control field is consecutive to the second legacy control field, the second NGV control field is consecutive to the first NGV control field, and the control information may include 1-bit information related to the NGV-LTF. The STA may transmit the NGV PPDU.

    摘要: Proposed are a method and device for receiving a PPDU in a wireless LAN system. 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 a first field and a second field. The first field includes an L-LTF. The first field is generated on the basis of a first or second phase rotation value. The first phase rotation value is generated on the basis of a third phase rotation value and a fourth phase rotation value. The third phase rotation value is a phase rotation value obtained by repeating a phase rotation value for an 80 MHz band defined in an 802.11be wireless LAN system.
