Abstract: Proposed are a method and a device for obtaining critical update information between MLDs in a wireless LAN system. Specifically, a reception MLD transmits a probe request frame to a transmission MLD through a first link. The reception MLD receives a probe response frame from the transmission MLD through the first link. The transmission MLD comprises a first transmission STA operating in the first link and a second transmission STA operating in a second link. The probe request frame comprises a change sequence element which requests critical update information of the second transmission STA. The probe response frame comprises the critical update information of the second transmission STA.

Abstract: In a Wireless Local Area Network system, a reception device can receive information about link deactivation, and deactivate a link. The proposed method includes receiving a physical protocol data unit (PPDU) including a first control field in a first link. In the method, the first control field may include information related to disablement of the first link and information on a time point at which the first link is disabled. The proposed method further includes disabling the first link based on the first control field.

IPC: H04W72/04
Abstract: In a wireless local area network system, a station (STA) generates a physical (PHY) protocol data unit (PPDU) including at least one subframe and information related to a subframe length, wherein the subframe may include a medium access control (MAC) protocol data unit (MPDU) and a padding bit. The length of the padding bit may be determined such that the length of the subframes is an integer multiple of a codeword length. The information related to the subframe length may be information on the number of codewords related to the subframe length. A step in which the STA transmits the PPDU may be comprised.
