1. A method in a wireless local area network (WLAN) system, the method comprising:
announcing, by a multi-link device (MLD) including a first station (STA) operating on a first link and a second STA operating on a second link, information related to the first link and the second link, wherein the first link and the second link are related to a non-simultaneous transmit and receive (NSTR) link pair;
invoking, by the first STA, a first Enhanced Distributed Channel Access (EDCA) back-off procedure related to setting a back-off counter of the first STA;
based on the back-off counter of the first STA reaching zero (0), determining, by the first STA whether to transmit a frame on the first link based on a condition related to the second STA; and
based on determining not to transmit the frame, invoking, by the first STA, a new EDCA back-off procedure related to setting the back-off counter.
