1. An apparatus of an extremely high-throughput (EHT) EHT access point (AP), the apparatus comprising: processing circuitry; and memory, the AP configured to operate as a first AP station (AP1) that is part of an AP multi-link device (AP MLD), the AP MLD being a first logical entity comprising at least two affiliated AP STAs including at least the AP1 and a second AP STA (AP2), the AP MLD configured to communicate over multiple links with a non-AP MLD (STA MLD) including at least a first link and a second link,
wherein for multi-link operation, the processing circuitry is configured to:
encode a management frame for transmission on the first link of the multiple links, the management frame encoded to include an element comprising a link ID bitmap identifying two or more of the multiple links including the second link to which the element applies; and
receive one or more medium access control (MAC) service data unit (MSDUs) from the STA MLD over two or more of the multiple links,
wherein when the element of the management frame is a target wake-up time (TWT) element, the link ID bitmap identifies two or more of the multiple links including the second link to which the TWT element applies.
