1. A non-access point (AP) multi-link device (MLD) associated with an AP MLD in a wireless network, the non-AP MLD comprising:
at least two stations (STAs), each STA being affiliated with the non-AP MLD; and
a processor coupled to the at least two STAs, the processor configured to:
set up enhanced multi-link multi-radio (EMLMR) links among multiple links between the non-AP MLD and the AP MLD;
operate in an EMLMR mode via the EMLMR links with the AP MLD, the EMLMR link including a first link and one or more second links;
transmit a first tunneled direct link setup (TDLS) discovery request frame to the AP MLD via the first link, the first link being set up between a first STA affiliated with the non-AP MLD and a first AP affiliated with the AP MLD; and
sequentially transmit one or more second TDLS discovery request frames to the AP MLD via the one or more second links when the non-AP MLD does not receive a TDLS discovery response frame from a TDLS peer STA in response to previously transmitted TDLS discovery request frame, wherein each second link is set up between a second STA affiliated with the non-AP MLD and a corresponding second AP affiliated with the AP MLD, and each second TDLS discovery request frame is associated with a respective one of the one or more second links.
