Abstract: Proposed are a method and a device for transmitting and receiving important update information of another AP through an ML element in a WLAN system. Specifically, a receiving MLD receives a basic ML element from a transmitting MLD over a first link. The receiving MLD decodes the basic ML element. The basic ML element includes a profile field of the second transmitting STA. The profile field of the second transmitting STA includes a first CSF presence field. When the value of the first CSF presence field is set to 0, the profile field of the second transmitting STA includes a first CSF field. The first CSF field includes information about the current change sequence number of the second transmitting STA.

Abstract: A method performed in a wireless local area network (LAN) system according to various embodiments is associated with a first station (STA) supporting multi-links comprising first and second links. A control field associated with an operating mode (OM) of the first STA can be associated with the on-off of the first link and/or the second link. The first and second links can each be a channel for various bandwidths defined in, for example, 2.4 GHz band, 5 GHz band and 6 GHz band. The first and second links can belong to the same or different bands. On-off information relating to each link can be formed on the basis of information such as an index or a control field bitmap associated with the operating mode.

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: The present specification proposes a method for resuming a PHY-level HARQ operation in a wireless local area network (WLAN) system. The method may include transmitting a resume signal including information related to resumption of hybrid automatic repeat request (HARQ) retransmission. The method may include transmitting a physical protocol data unit (PPDU) after transmitting the resume signal. The PPDU and the resume signal may be transmitted in different transmission opportunities (TXOPs).
