    Abstract: A method and an apparatus for transmitting and receiving data in a wireless LAN system are proposed. Specifically, an AP transmits control information to at least one STA. The AP transmits data to at least one STA or receives data from at least one STA, on the basis of the control information. The control information includes resource unit information for transmitting and receiving the data in a broadband. If the RU information is tone plan information for the full bandwidth of the broadband, the RU information includes allocation information that the broadband is composed of 12 guard tones, 4068 tones RU, 5 DC tones, and 11 guard tones. If the RU information is tone plan information to which OFDMA is applied for the broadband, the RU information includes allocation information that the broadband is composed of 12 guard tones, 2020 tones RU, 13 tones RU, 7 DC, 13 tones RU, 2020 tones RU, and 11 guard tones.

    Abstract: An example according to the present disclosure relates to a technique for identifying a wireless LAN (WLAN) packet. For example, when a physical protocol data unit (PPDU) includes a legacy signal field, a field contiguous to the legacy signal field may be used to identify a type of the PPDU. A field contiguous to the legacy signal field may include information indicating that the PPDU is an extreme high throughput (EHT) PPDU. The field contiguous to the legacy signal field may include at least one of information related to a frame format, a transmission opportunity, an STA ID, and/or a bandwidth.

    Abstract: According to various embodiments, a receiving station (STA) may receive a physical layer protocol data unit (PPDU). The PPDU may include a first signal field and a second signal field. The first signal field may include 3-bit information. The receiving STA may determine whether the PPDU is related to single user (SU) transmission or multiple user (MU) transmission, whether the PPDU is related to orthogonal frequency division multiple access (OFDMA), whether the PPDU is related to multi-user multiple input multiple output (MU-MIMO), and whether the PPDU is related to a trigger-based (TB) PPDU, based on the 3-bit information.

    Abstract: A method and apparatus for transmitting PPDU in a wireless LAN system are proposed. Specifically, a transmitter generates the PPDU, and transmits the PPDU to a receiver through a 320 MHz band in which some bands are punctured. The PPDU includes a legacy preamble and an EHT field. The legacy preamble includes L-STF and 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 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 having repeated a phase rotation value defined for an 80 MHz band in an 802.11ax system. The fourth phase rotation value is a phase rotation value defined in units of the 80 MHz band in the 320 MHZ band on the basis of an optimal PAPR of the L-LTF.

    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 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.
