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 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.

Abstract: Proposed are a method and apparatus for receiving a PPDU in a broadband in a wireless LAN system. Particularly, a reception STA receives a PPDU from a transmission STA through a band of 240 MHz and decodes the PPDU. The PPDU includes a control field and a data field. The control field includes information regarding a first tone plan of the band of 240 MHz. The first tone plan is set as a tone plan in which one of first through fourth bands of 80 MHz is punctured in a second tone plan of a band of 320 MHz defined in a 802.11be wireless LAN system. The second tone plan includes 12 left guard tones, 11 right guard tones, five DC tones, and a 4068-tone RU. The 4068-tone RU is an RU including 4068 tones.

Abstract: Proposed are a method and an apparatus for transmitting data in a wireless LAN system. Particularly, an AP transmits a PPDU to one STA. The AP transmits data to the one STA over a first NCCB band or a second NCCB band on the basis of the PPDU. The PPDU includes a first signal field and a second signal field. The first NCCB band is a 40 MHz or 60 MHz band generated by bonding a discontinuous 20 MHz band in an 80 MHz band. The second NCCB band is an 80 MHz, 100 MHz, 120 MHz, or 140 MHz band generated by bonding a discontinuous 20 MHz band in a 160 MHz band. The first signal field includes first information and second information. The first information is NCCB indication information on whether or not an NCCB can be performed. The second information is NCCB bandwidth information for a band to be used for transmitting the PPDU from the first NCCB band and the second NCCB band.

Abstract: A method and a device for transmitting a wake-up frame in a wireless LAN system are proposed. In particular, the transmission device configures a PPDU to which a first wireless LAN system is applied. The transmission device transmits, via the PPDU, a wake-up frame to which a second wireless LAN system is applied. The PPDU is transmitted via a first frequency band. The PPDU comprises a signal field and a data field. The signal field indicates that a data frame is transmitted in at least one RU excluding three 26-RUs located at the center of a second frequency band included in the first frequency band. The wake-up frame is transmitted via a 4 MHz band located at the center of the three 26-RUs. A coefficient is inserted in a first subcarrier constituting the 4 MHz band. The wake-up frame has an OOK scheme applied thereto and thus comprises an on signal and an off signal.
