Abstract: The specification proposes a method for requesting information on a restricted TWT when an STA has failed to receive the information. According to an embodiment of the present specification, when an STA fails to acquire information on a restricted TWT, the STA may transmit, to an AP, a signal for requesting the information on the restricted TWT after a certain time elapses from a TBTT. The signal may be transmitted independently or may be transmitted together with another signal transmitted by the STA.

Abstract: Proposed are a method and an apparatus for receiving an MAC address of another STA within a reception MLD in a wireless LAN system. Specifically, the reception MLD receives an ML element from a transmission MLD through a first link. The reception MLD decodes the ML element. The ML element includes common information and link information. The link information includes a profile field of the second transmission STA. The profile field of the second transmission STA includes first information relating to whether an MAC address of the second transmission STA exists. If the first information is configured to be 1, the profile field of the second transmission ST A includes the MAC address of the second transmission STA.

Abstract: Proposed are a method and device for switching between 320 MHz channels in a wireless LAN system. Specifically, a reception STA receives a beacon frame from a transmission STA through a first 320 MHz channel. The reception STA receives an EHT OM field from the transmission STA through the first 320 MHz channel. The reception STA receives a beacon frame from the transmission STA through a second 320 MHz channel. BSS channels of the transmission and reception STAs are switched from the first 320 MHz channel to the second 320 MHz channel on the basis of the beacon frame and the EHT OM field.

Abstract: A method and a device for transmitting updated information for an ML reconfiguration in a wireless LAN system are proposed. Specifically, a reception MLD performs an ML reconfiguration with a transmission MLD. The reception MLD transmits MLD capability information for the ML reconfiguration to the transmission MLD. The transmission MLD comprises a first transmission STA operating in a first link and a second transmission STA operating in a second link. The reception MLD comprises a first reception STA operating in the first link and a second reception STA operating in the second link. The MLD capability information includes information on a change in the number of links supported by the transmission and reception MLDs at the same time.

Abstract: The present specification proposes a method for a restricted TWT operation which has been improved and an apparatus for using the method. Particularly, according to an embodiment of the present specification, only when a specific condition is satisfied, a restricted TWT operation may be performed. Also, according to an embodiment of the present specification, an STA may determine whether or not to maintain a TXOP in progress prior to the start of a restricted TWT SP. In addition, according to an embodiment of the present specification, when the TXOP in progress is maintained prior to the start of the restricted TWT SP, the restricted TWT SP may be delayed.
