Abstract: Proposed are a method and device for transmitting an EHT PPDU in a wireless LAN system. Specifically, a transmission device generates an EHT PPDU and transmits the EHT PPDU to a receiving device through a 320 MHz RF band. 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 technique and a second technique. The first technique acquires an optimal PAPR in the L-STF and the L-LTF. The second technique acquires an optimal PAPR on the basis of the 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 phase rotation value. The second phase rotation value is obtained by repeating a phase rotation value defined for an 80 MHz band in an 802.11ax system. The third phase rotation value is defined in 80 MHz band units in a 320 MHz band.

Abstract: A method and a device for transmitting and receiving PPDU on the basis of FDR in a wireless LAN system are presented. More particularly, an AP transmits a trigger frame to an STA. The AP transmits downlink (DL) PPDU to the STA on the basis of the AP trigger frame. The AP receives uplink (UL) PPDU from the STA on the basis of the trigger frame. The trigger frame includes a first common information field. The first common information field includes a trigger type field, a length field, and a bandwidth field. The length field comprises information on the length of the longest PPDU of the DL PPDU and the UL PPDU. The bandwidth field comprises information on the total bandwidth over which the DL PPDU and the UL PPDU are transmitted. The DL PPDU and the UL PPDU are transmitted and received on the basis of FDR.

Abstract: A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, a transmission device generates a PPDU and transmits the PPDU to a reception device through a 320 MHz band. The PPDU includes a legacy preamble and an EHT field, and the legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value or a second phase rotation value. The first phase rotation value is obtained based on 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 defined when the PPDU is transmitted in an 80 MHz band four times. The fourth phase rotation value is a phase rotation value defined for each 80 MHz band in the 320 MHz band based on an optimal PAPR of the L-STF.

Abstract: Proposed are a method and a 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 phase rotation value. The first phase rotation value is [1 −1 −1 −1 −j j j j 1 −1 −1 −1 −j j j j]. One element of the first phase rotation value is a phase rotation value applied to each 20 MHz band of the 320 MHz band or the 160+160 MHz band.

Abstract: Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

Abstract: A method for providing ACK and/or NACK information in a WLAN system is proposed. The method proposes configuring a second PPDU in response to receiving a first PPDU. The second PPDU includes a legacy part, a control signal field, and a training field. The training field of the second PPDU may be configured based on whether the data field of the first PPDU is successfully received. The training field may be configured based on a first LTF sequence for indicating a successful reception of the first PPDU. The training field may be configured based on a second LTF sequence for indicating an error of the first PPDU.
