Abstract: The present invention relates to a wireless communication system. More particularly, a method and a device for restricted access window-based channel access in a WLAN system are disclosed. The method whereby a station (STA) performs channel access in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving restricted access window (RAW) cross-border transmission allowance (CBTA) information from an access point (AP) in case an RAW is allocated to the STA; and performing transmission by the STA on the basis of the RAW CBTA information. In case the RAW CBTA information is configured as a first value, transmission by the STA beyond the border of the RAW may be allowed.

Abstract: The present invention relates to a method for converting, by a station (STA), a non-traffic indication map (TIM) mode into a TIM mode and performing channel-accessing. According to the present invention, a station that does not receive a TIM or DTIM is to be switched so as to operate between a wakeup mode and a sleep mode for power saving. In order to set an efficient wakeup time, the STA may listen to beacon frame information from an AP and access a channel through information included in the beacon frame information.

Abstract: In a Wireless Local Area Network system, an STA may receive a trigger frame from an AP. The trigger frame may include a common information field and user information fields. Each of the user information fields may include a first field related to an association identifier (AID) and a second field including information for the STA related to the AID. The second field may include special information for every STA receiving the trigger frame on the basis that the first field has a specific value. The common information field may include a present field related to whether a user information field in which the first field has the specific value is present among the user information fields.

Abstract: The present disclosure proposes a method and device for using a coding subfield reserved for MU-MIMO in a wireless LAN system. Specifically, a receiving STA receives an MU PPDU from a transmitting STA. The receiving STA decodes the MU PPDU. The MU PPDU includes EHT-SIG and a data field. The EHT-SIG includes a common field and a user field. The user field includes a coding subfield and an MCS subfield. If the data field is transmitted in an RU or MRU having a size larger than a 242 RU on the basis of MU-MIMO, the coding subfield is reserved. If the value of the coding subfield is set to 0, the MCS subfield includes information on a second MCS different from a first MCS defined in an EHT wireless LAN system.

Abstract: Proposed are a method and apparatus for transmitting an ML element for ML reconfiguration in a wireless LAN system. In particular, a reception MLD generates a first ML element for ML reconfiguration. The reception MLD transmits the first ML element to a transmission MLD through a first link. The first ML element includes a profile sub-element of a second reception STA. The profile sub-element of the second reception STA includes a first STA control field. The first STA control field includes an entire profile sub-field. When a value of the entire profile sub-field is 1, the profile sub-element of the second reception STA includes entire information for the ML reconfiguration. When the value of entire profile sub-field is 0, the profile sub-element of the second reception STA does not include any information for the ML reconfiguration.
