Abstract: Proposed are a method and a device for transmitting and receiving a PPDU by setting a primary channel for each antenna port distributed in a DAS in a WLAN system. Specifically, a receiving STA receives control information from a transmitting STA. The receiving STA receives the PPDU from the transmitting STA on the basis of the control information. The transmitting STA operates in a system in which a plurality of antenna ports are distributed. The control information includes first indication information for a first primary 20 MHz channel and second indication information for a second primary 20 MHz channel.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system on the basis of tone plan-related control information. Specifically, a reception STA receives a PPDU from a transmission STA. The reception STA acquires tone plan-related control information by decoding the PPDU. The reception STA decodes a data field of the PPDU on the basis of the control information. If the PPDU is transmitted on the basis of non-OFDMA without puncturing, the tone plan is 2020-tone RU when the bandwidth of the PPDU is 160 MHz, the tone plan is 2×2020 tone RU when the bandwidth of the PPDU is 320 MHz, the tone plan is 3×2020 tone RU when the bandwidth of the PPDU is 480 MHz, and the tone plan is 4×2020 tone RU when the bandwidth of the PPDU is 640 MHz.

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: Proposed are a method and a device for configuring a spatial reuse field in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB PPDU to the transmission STA through a pre-configured frequency band. The trigger frame comprises a common information field and a special user information field. The common information field comprises first to fourth spatial reuse fields. The special user information field comprises fifth and sixth spatial reuse fields. When the pre-configured frequency band is a 20 MHz band, the first to fourth spatial reuse fields are configured by the value of the fifth spatial reuse field.
