Abstract: In a wireless local area network (WLAN) system, an STA MLD may include a first STA and a second STA, wherein the first STA operates on a first link, and the second STA operates on a second link. The STA MLD may transmit an association request frame to an access point (AP) MLD. The association request frame may include capability information of a requesting STA, which requests to be associated with the AP MLD, among STAs included in the STA MLD and information related to a request link, to with which a request to be associated is transmitted by the requesting STAs. The STA MLD may receive an association response frame from the AP MLD. The association response frame may include capability information of an AP that operates in a link, an association with which is accepted by the AP MLD, among the request links.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a first link and a second link may transmit information on data buffered in the MLD through a first station (STA) operating in an awake state. The information on the data buffered in the MLD may include a first information field related to the first STA and a second information field related to a second STA.

Abstract: An Internet of Things (IoT) device may transmit, to a Blockchain Node, a registration request signal including a public key certificate of the IoT device and a universally unique identifier (UUID) of the IoT device. The IoT device may receive, from the Blockchain Node, a first certification identifier (ID) for the IoT device, wherein the first Certification ID is a newly generated block. The IoT device may receive a first encrypted signal from an onboarding tool (OBT), wherein the encrypted signal includes a second certification ID of the OBT and encrypted information being encrypted based on a private key of the OBT. And, the IoT device may transmit, to the Blockchain Node, a verification request signal including the second certification ID of the OBT.
