1. A method in a wireless local area network (WLAN) system, the method comprising:
generating, by a station (STA) affiliated with a multi-link device (MLD), an Association Request frame including a multi-link element,
wherein the multi-link element includes a multi-link control field, and a common information field which is contiguous to the multi-link control field,
wherein the multi-link control field includes a first present field related to presence/absence of a link information field, and the first present field has a length of 1 bit,
wherein the link information field has a length of 4 bits and is related to a number of stations affiliated with the MLD that support simultaneous transmission or reception of frames on respective links,
wherein the common information field includes the link information field based on the first present field,
wherein the common information field further includes a Medium Access Control (MAC) address field related to the MLD;
transmitting, by the STA, the Association Request frame; and
receiving, by the STA, an Association Response frame.
