1. A method in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a first non-access point (AP) station (STA), a multi-link probe request frame to a first AP; and
receiving, by the first non-AP STA, a multi-link probe response frame from the first AP,
wherein the first AP operating on a first link and a second AP operating on a second link are affiliated with an AP multi-link device (MLD),
wherein the first non-AP STA operating on the first link and a second non-AP STA operating on the second link affiliated with a non-AP MLD,
wherein the multi-link probe request frame includes a profile field for the second AP,
wherein the profile field for the second AP includes a first Complete Profile Requested subfield of a first STA Control field,
wherein based on the first non-AP STA requesting partial information on the second AP, a value of the first Complete Profile Requested subfield is set to 0, and the profile field for the second AP further includes a first request element, and
wherein the partial information on the second AP is requested based on the first request element.
