1. A method in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a non-access point (AP) station (STA), a multi-link probe request to a first AP; and
receiving, by the non-AP STA, a multi-link probe response 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 non-AP STA operating on the first link is affiliated with the non-AP MLD,
wherein based on a Probe Request Multi-Link element carrying a Per-STA Profile subelement for the second AP, the multi-link probe request allows the non-AP STA to request the first AP to include a partial profile for the second AP,
wherein the multi-link probe request includes a first Request element and a Probe Request Multi-Link element,
wherein the Per-STA Profile subelement for the second AP includes a first Complete Profile Requested subfield, and
wherein based on the non-AP STA requesting the same partial profile for the second AP and the first AP, the first Request element is included in a frame body of the multi-link probe request and is not carried in the Per-STA Profile subelement for the second AP, the first Request element is inherited for the second AP, and a value of the first Complete Profile Requested subfield is set to 0.
