1. A non-access point (AP) multi-link device (MLD), comprising:
stations (STAs), each comprising a transceiver configured to form a link with a corresponding AP of an AP MLD; and
a processor operably coupled to the STAs, the processor configured to:
detect a non-simultaneous transmit and receive (NSTR) link pair;
detect that respective links of the NSTR link pair have transmit opportunity (TXOP) durations having different values; and
manage communication on the respective links of the NSTR link pair based on access categories (ACs) to reduce interference between the respective links of the NSTR link pair,
wherein to manage the communication on the respective links of the NSTR link pair, the processor is configured to:
determine the respective link of the NSTR link pair having a longer data unit (DU) duration based on the ACs; and
divide the DU for the respective link having the longer DU duration into two or more DUs that are configured to be transmitted as part of a same TXOP.
