at a first multi-link device (MLD) that supports a first link, link1, and a second link, link2, transmitting a first frame during a first Transmission Opportunity (TXOP) on link1, and a second frame during a second TXOP on link2, simultaneously to a second MLD;
receiving, at the first MLD, a first response frame to the first frame transmitted on link1 after a transmission end time of the first frame;
identifying, at the first MLD, that a response frame to the second frame transmitted on link2 was not received after the transmission end time of the second frame; and
