1. A method in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a receiving multi-link device (MLD), a probe request frame to a transmitting MLD through a first link; and
receiving, by the receiving MLD, a probe response frame from the transmitting MLD through the first link,
wherein the transmitting MLD includes a first transmitting station (STA) operating in the first link and a second transmitting STA operating in a second link,
wherein the receiving MLD includes a first receiving STA operating in the first link and a second receiving STA operating in the second link,
wherein the probe request frame includes a frame body and a profile field of the second receiving STA,
wherein when the first receiving STA does not request complete information on the first link and requests complete information on the second link, the complete information on the second link is requested based on the profile field of the second receiving STA,
wherein the probe response frame does not include the complete information on the first link, and includes only the complete information on the second link, and
wherein the frame body does not include a field for requesting the complete information on the first link.
