1. An apparatus for an access point (AP) multi-link device (MLD), the AP MLD comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a first Traffic Indication Map (TIM) element with a first bitmap for a first communication link, indicating traffic to be sent by a first AP device of the AP MLD to a first non-AP device of a non-AP MLD during a beacon interval;
generate a second TIM element with a second bitmap for a second communication link, indicating no traffic to be sent by a second AP device of the AP MLD to a second non-AP device of the non-AP MLD during the beacon interval;
include a Multi-Link Traffic Indication element in the first TIM element and the second TIM element, containing per-link traffic indication bitmap(s) for non-AP MLD(s), managing transmissions over multiple wireless links within the AP MLD;
utilize a Partial Virtual Bitmap subfield of a TIM element in a beacon frame, with the Multi-Link Traffic Indication element counting from a bit position corresponding to an Association Identifier (AID) value in an AID Offset subfield of the Multi-Link Traffic Indication element; and
cause to send, using the first AP device of the AP MLD and the first communication link, the beacon frame, the beacon frame comprising the first TIM and the second TIM.
