    Abstract: The present specification proposes a technical feature for increasing a transmission range of a wireless LAN signal. The wireless LAN signal of the present specification, e.g. a transmission physical protocol data unit (PPDU), may be configured on the basis of a duplicate transmission mode. The transmission PPDU of the present specification may comprise a data unit duplicated in frequency . The data unit duplicated in frequency may be configured on the basis of a total bandwidth of the transmission PPDU. The transmission PPDU of the present specification proposes various training fields for the duplicated data unit.

    Abstract: A transmission STA in a wireless local area network system can transmit a sensing start frame. The sensing start frame can comprise information relating to a feedback method and feedback frequency. The feedback method can comprise information relating to at least one of an explicit feedback, implicit feedback and hybrid feedback. The transmission STA can transmit a sensing frame to a reception STA. The transmission STA can receive from the reception STA a feedback frame comprising channel state information obtained on the basis of the sensing frame. The sensing start frame can further comprise information relating to the number of sensing frame transmissions. The information relating to feedback frequency can comprise information relating to the number of received sensing frames prior to the transmission of the feedback frame by the reception STA.

    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 PPDU includes a legacy preamble and a first and a second signal field. The legacy preamble and the first and second signal fields are generated on the basis of a first and a second phase rotation value. When the broadband corresponds to a 320 MHz band, the first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1]. An element of the first phase rotation value is applied to each 20 MHz band of the 320 MHz band. An element of the second phase rotation value is applied to each subcarrier of the 320 MHz band.

    Abstract: Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA via a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a band of 320/160+160 MHz including a primary channel of 160 MHz and a secondary channel of 160 MHz, the data field is received via a first multiple RU in which a 996-RU and a 484-RU are aggregated. The first multiple RU is allocated within the primary channel of 160 MHz or the secondary channel of 160 MHz.

    Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU through a broadband from a transmission STA, 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 the broadband. The first STF sequence is obtained by applying a phase rotation to a sequence in which a second STF sequence for a 80 MHz band is repeated. The first STF sequence is a sequence in which a preconfigured M sequence is repeated, and is defined by a formula {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). A first preamble puncturing pattern includes all patterns of a band obtained by puncturing a 20 MHz band in the 320 MHz band or the (160+160) 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.
