    Abstract: Proposed are a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives the EHT PPDU from a transmission STA through a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information about a pilot tone. The information about the pilot tone includes allocation information indicating that a first pilot tone for the 320 MHz band is configured by repeating a second pilot tone for an 80 MHz band defined in an 802.11ax wireless LAN system. The first pilot tone is received in a data field on the basis of the allocation information.

    Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband communication and decodes the PPDU. The PPDU is received on the basis of an OFDMA scheme. The PPDU includes a first signal field. The first signal field includes first information on a preamble puncturing pattern for each 80 MHz band in the broadband communication. The first information consists of a 4-bit bitmap for the 80 MHz band.

    Abstract: In a wireless local area network (LAN) system, a station (STA) can generate a plurality of long training field (LTF) symbols used for a plurality of streams including first to fourth streams. The first to fourth streams use different LTF sequences, and the LTF sequences used by the first to fourth streams may be multiplied by the same element of a P matrix. The STA may include a step for transmitting a PHY protocol data unit (PPDU) including the plurality of LTF symbols.

    Abstract: The present is related to a wireless local area network (WLAN) system. A transmitting station (STA) may generate a physical protocol data unit (PPDU), and the transmitting STA may transmit the PPDU over a 320 MHz band, wherein the PPDU may include a long training field (LTF) signal which may be generated on the basis of an LTF sequence for the 320 MHz band.

    Abstract: An example according to the present specification relates to a technique for configuring a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may comprise an L-SIG field, an RL-SIG field, a first control field, and a second control field. A result of “modulo 3 operation” for a length field value of the L-SIG field may be set to “0.” The RL-SIG field may be configured to be the same as the L-SIG field. The first control field may comprise 3-bit information on the version of a PPDU, 6-bit information on a BSS color, and 7-bit information on TXOP.

    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: A transmission and reception PPDU according to the present specification may include a first control signal field and a second control signal field. Overflowed information from the first control signal field may include a first encoding block of a common field of the second control signal field. In addition, the common field of the second control signal field may include various numbers of encoding blocks and various numbers of RU allocation subfields on the basis of the characteristics of the transmission and reception PPDU. In addition, the overflowed information may be included in a plurality of content channels using various methods.
