1. A method of transmitting a group addressed frame, the method comprising:
at an access point (AP) multi-link device (MLD), determining that a first non-AP MLD is wirelessly transmitting over a first wireless link of a non-simultaneous transmit and receive (NSTR) link pair;
the AP MLD wirelessly transmitting an individually addressed frame to a second non-AP MLD over a second wireless link of the NSTR link pair; and
the AP MLD wirelessly transmitting a group addressed frame to be received by the second non-AP MLD over the second wireless link after the first non-AP MLD is done transmitting, wherein the first non-AP MLD and second non-AP MLD refrain from transmitting on the NSTR link pair during transmission of the group addressed frame without changing wireless links.
