1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a second station (STA) operating on a second link, a first request to send (RTS) frame on the second link, wherein the second STA is included in a receiving multi-link device (MLD), wherein the receiving MLD further includes a first STA operating on a first link, wherein the first STA is a transmission opportunity (TXOP) responder, wherein the first link and the second link are a non-simultaneous transmit and receive (STR) link pair;
skipping, by the second STA, clear to send (CTS) frame transmission for the first RTS frame, based on that the first STA is the TXOP responder; and
receiving, by the second STA, a physical protocol data unit (PPDU) on the second link.
