1. A method performed by a multi-link device (MLD) operating in a plurality of links in a wireless local area network system, the method comprising:
receiving a physical layer protocol data unit (PPDU) through a first link among the plurality of links,
wherein the PPDU includes control information related to a second link distinct from the first link among the plurality of links, and
wherein the control information related to the second link includes a first information field related to a link identifier of the second link and a second information field related to whether complete element information for the second link or partial element information for the second link is included in the PPDU, and the second information field has a length of one bit; and
obtaining the complete element information for the second link based on the first information field and the second information field.
