    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.

    Abstract: The present disclosure proposes a method and a device for configuring a trigger frame including control information for DL A-PPDU in a WLAN system. Specifically, a receiving STA receives a trigger frame from a transmitting STA. The receiving STA receives, from the transmitting STA, a triggered DL A-PPDU on the basis of the trigger frame. The trigger frame includes a common information field, an HE modified user information field, and an EHT modified user information field. The common information field includes a trigger type subfield, a DL BW subfield, a DL BW Extension subfield, and a first reserved subfield. The HE modified user information field includes a first AID12 subfield, a first RU allocation subfield, and a second reserved subfield. The EHT modified user information field includes a second AID12 subfield, a second RU allocation subfield, and a PS160 subfield.

    Abstract: The present disclosure proposes a method and device for transmitting capability information about a reception STA in a wireless LAN system. Specifically, the reception STA generates and transmits capability information about the reception STA to a transmission STA. The capability information about the reception STA includes an HE Capabilities element and an EHT Capabilities element. The HE Capabilities element includes a Supported EHT-MCS And NSS Set field. The EHT Capabilities element includes a Supported EHT-MCS And NSS Set field. The Supported EHT-MCS And NSS Set field includes first to fourth sub-fields. When the reception STA is a non-AP STA operating only at 20 MHz and is allocated to a first transmission bandwidth, the first sub-field includes information about the maximum number of spatial streams that the reception STA can transmit and receive in each MCS.

    Abstract: A method and an apparatus for transmitting an EHT PPDU to a WLAN system are proposed. Specifically, a transmitter generates and transmits an EHT PPDU to a receiver through a 320 MHz band from which an 80 MHz band is punctured. The EHT PPDU includes a legacy preamble and an EHT field. The 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 obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in unit of the 80 MHz band in the 320 MHz band on the basis of an optimal PAPR of the L-STF and L-LTF. The first phase rotation value is [1 1 −1 −1 −j −j j j 1 1 −1 −1 −j −j j j].
