Abstract: A method and a device for transmitting data in a wireless LAN system are proposed. Specifically, an AP transmits a band switch announcement element through a first band supported by a first and a second RF. The AP changes the first band, supported by the second RF, to a second band on the basis of the band switch announcement element. The AP transmits first data to an STA through the first band supported by the first RF and the second band supported by the second RF. The first data is transmitted through a multiple band in which the first band and the second band are combined.

Abstract: One example according to the present specification relates to a technique for forming a midamble in a wireless LAN (WLAN) system. A reception STA may receive an NGV PPDU. The NGV PPDU may include a preamble, a data field, and a midamble. The midamble format may be determined as either a first format or a second format. A midamble symbol of the first format may include an LTF signal and a GI pertaining to the LTF signal.

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.

Abstract: An example according to the present specification relates to a technique for identifying a wireless LAN (WLAN) packet. An NGV PPDU may include a first legacy control field and a second legacy control field. The second legacy control field may be used to identify a type of a PPDU. The first legacy control field may be received through a first symbol, and the second legacy control field may be received through a second symbol. The first legacy control field and the second legacy control field may include identical bit information.

Abstract: One embodiment according to the present specification relates to a method for transmitting, from a first link, information for setting a NAV in a second link. When transmission STA performs communication through a second link, the transmission STA can transmit, through a first link, information for setting the NAV for the second link in another STA. Particularly, the transmission STA can receive, from the second reception STA, a second frame through the second link. The transmission STA can transmit, to a first reception STA, a first frame through the first link during the reception of the second frame. The first frame can include information for setting the NAV for the second link. The first reception STA can set the NAV for the second link on the basis of the first frame.
