Abstract: Methods and apparatuses for facilitating the coexistence of enhanced multi-link single radio (EMLSR) operation with target wake time (TWT) operation in a wireless local area network. A non-access point (AP) MLD comprises STAs, each comprising a transceiver that forms a link with a corresponding AP of an AP MLD, and a processor.
