Enhancing roaming performance with multi-link operation

A multi-link device, comprising:

• a multi-link communication interface comprising a first set of radio resources and a second set of radio resources;
• a processor;
• and
• a memory communicatively coupled to the processor, wherein the memory comprises a roaming management logic that is configured to:
• associate with an access point (AP) over a first link using the first set of radio resources and a second link using the second set of radio resources;
• exchange traffic with the AP over the first link;
• indicate to the AP that the second link is unavailable;
• and
• scan, upon indicating to the AP that the second link is unavailable, for a roaming candidate AP using the second set of radio resources of the second link, while concurrently having the first link operational to exchange the traffic with the AP.

A method for roaming, comprising:

• by a multi-link device:
• associating with an access point (AP) over a first link using a first set of radio resources and a second link using a second set of radio resources;
• exchanging traffic with the AP over the first link;
• indicating to the AP that the second link is in a power save mode;
• and
• scanning, upon indicating to the AP that the second link is in the power save mode, for a roaming candidate AP using the second set of radio resources of the second link, while having the first link operational with the AP to exchange the traffic.
