1. A method comprising:
detecting, by an access point (AP) multi-link device (MLD), a trigger condition for a retry on a first link;
in response to detecting the trigger condition, selecting, by the AP MLD, a second link from a plurality of links based on channel utilizations of the links, power save (PS) statuses of the links, and frame retry rates of the links;
selecting, by the AP MLD, a retry mode from a plurality of retry modes for the second link based on at least one of a received signal strength indicator (RSSI), a channel utilization, a packet length, a historical retry mode, and a total number of retries; and
transmitting, by the AP MLD, a retry packet on the second link using the selected retry mode.
