1. A method for a wireless local area network system, the method performed by an access point (AP) multi-link device (MLD) and comprising:
receiving, from a non-simultaneous transmit and receive (NSTR) station MLD (NSTR STA MLD), a Multi-Link element including transmit power information for the NSTR STA MLD to operate in STR based on a simultaneous transmit and receive (STR) mode, wherein the NSTR STA MLD includes a first STA and a second STA, the first STA operating in a first link, the second STA operating in a second link, wherein the first and second links are part of an NSTR link pair, wherein the Multi-Link element further includes frequency separation information for the STR mode, maximum link number information of the NSTR STA MLD, and Traffic Identifier (TID) mapping information of the NSTR STA MLD, wherein the frequency separation information is related to a frequency distance between the first and second links for operating based on the STR mode, wherein the maximum link number information is related to a number of maximum links supported by the NSTR STA MLD, and wherein the TID mapping information is related to at least one TID allowed to be exchanged on the first and second links;
receiving, from the NSTR STA MLD, a reference signal to calculate a path loss value between the NSTR STA MLD and the AP MLD, the reference signal including a transmit power value of the reference signal; and
determining, based on the Multi-Link element and the path loss value, whether the NSTR STA MLD is allowed to operate based on the STR mode.
