Abstract: A method and apparatus for transmitting a PPDU on the basis of S-TDMA in a wireless LAN system are presented. In particular, an AP generates a PPDU, and transmits the PPDU to a first STA and a second STA. When a PPDU further comprises a third signal field, the third signal field comprises information about S-TDMA. The information about S-TDMA comprises STDMA indication information indicating that S-TDMA can be carried out, first symbol offset information about a first data field, and second symbol offset information about a second data field. The S-TDMA indication information comprises information indicating that the first and second data fields are assigned to a first RU. The first data field is transmitted from the first RU during a first symbol determined on the basis of the first symbol offset information. The second data field is transmitted from the first RU during a second symbol determined on the basis of the second symbol offset information.

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.

Abstract: Proposed are a method and a device for requesting the same partial information for all transmission STAs within a transmission MLD and responding thereto in a wireless LAN system. Specifically, a reception MLD transmits an ML probe request frame through a first link from the transmission MLD. The reception MLD receives an ML probe response frame through the first link from the transmission MLD. The ML probe request frame includes a first frame body and a probe request ML element. When the first reception ST A requests the same partial information for all transmission STAs, the first frame body includes a first request element and the probe request ML element does not include a profile sub-element of the second transmission STA.
