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: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20 MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.

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: A method and device for transmitting an NGV frame in a wireless LAN system is proposed. Specifically, a transmission device generates an NGV frame and transmits the NGV frame through a first band. The NGV frame includes an L-STF, an L-LTF, an L-SIG, an NGV-SIG, an NGV-STF, an NGV-LTF, and NGV-Data. The L-STF, the L-LTF, the L-SIG, and the NGV-SIG are duplicated in units of second bands and transmitted through the first band. The NGV-STF, the NGV-LTF, and the NGV-Data are transmitted through a full band of the first band. The first band is a 20 MHz band, and a second band is a 10 MHz band.

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 RF. 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.
