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.

Abstract: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wide band, and decodes the PPDU. The PPDU includes a legacy preamble, and first and second signal fields.

Abstract: Disclosed are a method and device for transmitting/receiving a NDP feedback report response in a wireless LAN system. The method for transmitting a NDP feedback report response, according to one embodiment of the present disclosure, may comprise the steps of: receiving, from an AP, a NFRP trigger frame for requesting for a NDP feedback report response; and transmitting, to the AP, as a response to the NFRP trigger frame, a PPDU for carrying the NDP feedback report response.
