Group addressed frame delivery over multi-link systems

A computer-implemented method comprising:

• identifying, by an access point (AP) multilink device (MLD) in a wireless network, a data frame that is to be transmitted to a plurality of non-AP MLDs subject to a groupcast with retry (GCR) block acknowledgement (BA) agreement;
• identifying, by the AP MLD, respective communication links by which the AP MLD is communicatively coupled with the non-AP MLDs;
• transmitting, by the AP MLD, the data frame on each of the respective communication links;
• and
• transmitting, by the AP MLD based on transmission of the data frame, a BA request (BAReq) on respective ones of the communication links to the non-AP MLD;
• and
• wherein a different BAReq is transmitted for each of the non-AP MLDs.

A computer-implemented method comprising:

• identifying, by a non-access point (AP) multilink device (MLD) in a wireless network, a first frame received on a first link and a second frame received on a second link;
• processing, by a group frames and reorder buffer of the non-AP MLD, the first frame and the second frame to identify:
• (a) whether the first frame and second frame are duplicates of one another;
• and
• (b) whether the first frame and second frame have a sequence number (SN) that is in accordance with a pre-identified order;
• and
• outputting, by the group frames and reorder buffer of the non-AP MLD, the first frame and the second frame to a PN check and decryption block when the first frame and second frame are not duplicates of one another and have respective SNs that are in accordance with the pre-identified order.
