1. A method, comprising:
receiving a trigger frame from an access point (AP) by a station (STA) affiliated with a multi-link device (MLD) on a first link of a non-simultaneous-transmission-and-reception (NSTR) link pair;
determining whether the STA is in a blindness condition on the first link responsive to receiving the trigger frame; and
responsive to determining that the STA is in the blindness condition, transmitting a trigger-based (TB) physical-layer protocol data unit (PPDU) on the first link under the blindness condition on the first link with at least one restriction.
 
13. A method, comprising:
receiving a control frame from an access point (AP) by a station (STA) affiliated with a multi-link device (MLD) on a first link of a non-simultaneous-transmission-and-reception (NSTR) link pair;
determining whether the STA is in a blindness condition on the first link; and
responsive to determining that the STA is in the blindness condition, transmitting a control response frame on the first link under the blindness condition on the first link with at least one restriction.
