Abstract
In a wireless local area network system, a reception multi-link device (MLD) may not transmit a CTS frame, even if the reception multi-link device receives an RTS frame via a second link, in the case that an STA operating via a first link is a TXOP responder.
Claims12
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.

A receiving multi-link device (MLD) used in a wireless local area network (WLAN) system, the receiving MLD comprising:
- a first station (STA) operating on a first link;
- and
- a second STA operating on a second link,
- wherein the first STA is a transmission opportunity (TXOP) responder, and
- wherein the first link and the second link are a non-simultaneous transmit and receive (STR) link pair,
- wherein the receiving MLD is adapted to:
- receive, by the second STA, a first request to send (RTS) frame on the second link;
- skip, 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
- receive, by the second STA, a physical protocol data unit (PPDU) on the second link.
