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.

A method performed in a multi-link device (MLD) operating in a first link and second link of a wireless local area network (WLAN) system, the method comprising:
- performing an association process;
- obtaining a first identifier (ID) for the first link and a second ID for the second link, based on the association process,
- wherein the first ID for the first link has a length of 4 bits, and the second ID for the second link has a length of 4 bits;
- identifying data buffered in the MLD;
- identifying a first station (STA) operating in an awake state out of the first STA related to the first link and a second STA related to the second link, which are included in the MLD;
- and
- transmitting information on the data buffered in the MLD through the first STA,
- wherein the information on the data buffered in the MLD includes a first information field related to the first STA and a second information field related to the second STA,
- wherein the first information field includes the first ID for the first link and information on a queue buffered in the first STA, and
