    Abstract: A method and device for transmitting an NGV frame in a wireless LAN system is proposed. Specifically, a transmission device generates an NGV frame and transmits the NGV frame through a first band. The NGV frame includes an L-STF, an L-LTF, an L-SIG, an NGV-SIG, an NGV-STF, an NGV-LTF, and NGV-Data. The L-STF, the L-LTF, the L-SIG, and the NGV-SIG are duplicated in units of second bands and transmitted through the first band. The NGV-STF, the NGV-LTF, and the NGV-Data are transmitted through a full band of the first band. The first band is a 20 MHz band, and a second band is a 10 MHz band.

    Abstract: Provided is a method and device for transceiving a frame in a wireless LAN system. Particularly, an AP transmits a first frame to a first STA via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a DL transmission and a UL transmission. The relationship between the first STA and the second STA is a hidden node. A PHY header of the first frame includes channel status information of the second band. An NAV of the first STA is set up on the basis of the channel status information.

    Abstract: A method for a non-simultaneous transmit and receive (non-STR) device in a wireless local area network (LAN) is provided. The non-STR device may support a multi-link communication related to a first link and a second link. The non-STR device may determine whether to transmit a first physical protocol data unit (PPDU), PPDU, based on a channel access result on the first link and a channel access result on the second link. The non-STR device determines not to transmit the first PPDU through the first link and keeps the back-off counter of the first link at zero (0) when a back-off counter of the first link reaches zero (0) and a back-off counter of the second link does not reach zero (0).

    Abstract: A method and apparatus for communicating in a wireless LAN system are disclosed. The method by which a first station (STA) communicates in a wireless LAN system comprises the steps of: performing, with a second STA, a restricted target wake time (r-TWT) membership setup procedure; and receiving, from the second STA, r-TWT schedule information included in a broadcast TWT element, wherein, on the basis that a specific portion of a first transmission opportunity (TX-OP) in a r-TWT service period (SP) notified by the r-TWT schedule information is not used for downlink (DL) frame transmission corresponding to at least one r-TWT DL traffic identifier (TID) or uplink (UL) frame request corresponding to at least one r-TWT UL TID, the first TXOP may be terminated before the start time of the r-TWT SP.

    Abstract: Proposed are a method and apparatus for performing sensing in a wireless LAN system. Specifically, a first STA transmits a sensing request frame to a second STA. The first STA receives a first sensing response frame form the second STA. The first STA transmits a sensing signal to the second STA or receives the sensing signal from the second STA. The sensing request frame includes a transmission parameter set, a measurement and feedback parameter set, and a transmission method of the sensing signal. The sensing response frame includes a first indicator indicating whether to use at least one transmission parameter included in the transmission parameter set and a second indicator indicating whether to use at least one measurement and feedback parameter included in the measurement and feedback parameter set.
