1. A method in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a multi-link device (MLD) connected to a plurality of links including a first link and a second link, a request frame including an information field for requesting complete elements included in an element set designated for the second link to a first access point (AP) of an AP MLD, through a first station (STA) included in the MLD, wherein the first STA operates on the first link; and
receiving, by the MLD, a response frame from the first AP through the first STA, based on the request frame, wherein the response frame includes complete elements included in the element set designated for the second link,
wherein the request frame includes 1-bit information on whether the complete elements or partial elements of a second AP are requested,
wherein based on the 1-bit information being set to 1, the complete elements of the second AP are requested, and
wherein based on the 1-bit information being set to 0, the partial elements of the second AP are requested.
