US 12,757,230 B2 · Reliable frame transmission scheme for multi-link device

Abstract

In implementations of the present disclosure, there is provided an approach for transmitting a broadcast frame (BC) or a multicast (MC) frame. A method comprises obtaining a BC frame or an MC frame. Moreover, multiple links used by an access point (AP) multi-link device (MLD) are determined. Then, a master link is selected from the multiple links based on the usage condition of the multiple links. The BC frame or the MC frame is converted to a unicast frame for the master link. Next, the unicast frame is transmitted to a station MLD of the set of stations by using the master link. Implementations of the present disclosure can reduce a waste of time for a station MLD, a waste of channel resources, and serious issues for dynamic multicast optimization on the station side.

Dependent claims

A method comprising:

obtaining, by an access point (AP) multi-link device (MLD), a first broadcast (BC) frame, or a first multicast (MC) frame;
determining, by the AP MLD, multiple links used by the AP MLD, the multiple links being linked between the AP MLD and a set of stations including station MLDs;
determining, by the AP MLD and based on usage condition of the multiple links, a master link from the multiple links;
converting, by the AP MLD, the first BC frame or the first MC frame to a unicast frame for the master link;
transmitting, by the AP MLD and by using the master link, the unicast frame to a station MLD of the set of stations;
determining that a second BC frame or a second MC frame is to be transmitted on the multiple links;
determining an aligned delivery traffic indication message (DTIM) period based on multiple DTIM periods for the multiple links;
and
transmitting the second BC frame or the second MC frame with the aligned DTIM period.
