This disclosure describes systems, methods, and devices related to multi-link traffic steering. A device may establish one or more links with a station multi-link device (STA MLD), wherein the STA MLD comprises one or more logical entities defining separate station devices. The device may generate a traffic indication map (TIM) bitmap of a plurality of bits, wherein one or more bits are associated with an association identification (AID) corresponding to the STA MLD. The device may set the one or more bits to a first value to indicate that there is data to be retrieved by the STA MLD on any of the one or more links. The device may generate one or more beacon frames each comprising a same TIM element, wherein the TIM element comprises the TIM bitmap. The device may cause to send one or more beacon frames on each of the one or more links.
