1. A method performed in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a non-access point (non-AP) station (STA) affiliated with a non-AP multi-link device (MLD), an Association Request frame to an AP MLD,
wherein the Association Request frame includes a link identifier (ID) field identifying at least one link that is requested for setup with the AP MLD, wherein the Association Request frame further includes a 1-bit control field being contiguous to the link ID field,
wherein a per-STA profile for at least one STA carries one of two types of profiles, wherein the two types of profile are a complete profile and a partial profile,
wherein to request the at least one link to be setup, the Association Request frame carries the complete profile of a corresponding non-AP STA affiliated with the non-AP MLD,
wherein the Association Request frame further includes a link mapping field carrying a bitmap related to traffic identifiers (TIDs) being mapped to the at least one link associated with the link ID,
wherein the Association Request frame further includes information indicating whether a link pair related to the at least one link is a simultaneous transmit and receive (STR) link pair; and
receiving an Association Response frame from the AP MLD,
wherein the Association Response frame indicates status information indicating whether the at least one link that is requested for the setup is accepted or not,
wherein based on the at least one link being accepted, the Association Response frame carries the complete profile of a corresponding AP affiliated with the AP MLD.
