1. A method in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a first non-access point (non-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, a second AP operating on a second link and a third AP operating on a third link are affiliated with an AP multi-link device (MLD),
wherein the first non-AP STA operating on the first link is affiliated with a non-AP MLD,
wherein based on the multi-link probe request frame including per-STA profiles for the second AP and the third AP, only APs whose link ID is equal to a value in a Link ID field in the per-STA profiles for the second AP and the third AP in the multi-link probe request frame are the second AP and the third AP, and
wherein the multi-link probe request frame allows the first non-AP STA to request information on all APs affiliated with the AP MLD, based on the multi-link probe request frame not including any per-STA profile.
