Abstract: One example according to the present specification relates to a scheme for transmitting a PPDU in a wireless LAN (WLAN) system. A transmission STA can determine whether both a first channel and a second channel are idle. The transmission STA can configure backoff count values associated with the first channel and the second channel. The transmission STA can reduce the backoff count values on the basis of the first channel and the second channel. The transmission STA can transmit an NGV PPDU on the basis of the backoff count values.

Abstract: A method and an apparatus for transmitting a PPDU on the basis of an S-TDMA in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP receives, on the basis of the trigger frame, a first trigger-based frame from the first STA and a second trigger-based frame from the second STA. The trigger frame includes a common information field and a user information field. The common information field includes S-TDMA indication information enabling the S-TDMA to be performed. The user information field includes: allocation information on a first RU to which the first trigger-based frame and the second trigger-based frame are transmitted; first symbol offset information on the first trigger-based frame; and second symbol offset information on the second trigger-based frame.

Abstract: A transmitting multi-link device (MLD) in a wireless local area network system enables a first station (STA) to perform a back-off operation again without transmitting PPDU, if a second STA is in the middle of receiving even when a back-off counter (BC) of the first STA becomes 0. The first STA and the second STA are included in the same transmitting MLD. The first STA operates on a first link and the second STA operates on a second link. The first and second links are included in a non-simultaneous transmit and receive (NSTR) link pair.

Abstract: Proposed are a method and device for performing backoff and channel access on antenna ports distributed in a DAS in a wireless LAN system. Specifically, a reception STA checks whether one or more of a plurality of antenna ports are idle. When one or more of the antenna ports are idle, the reception STA performs backoff on the one or more antenna ports. When a counter of the backoff becomes 0, the reception STA performs channel access on a first channel that is commonly idle in the one or more antenna ports. The reception STA receives a PPDU from a transmission STA through the first channel.
