A non-access point (non-AP) multi-link device (MLD) is arranged to roam within a roaming AP MLD comprising a plurality of AP MLDs. The non-access point MLD receives from the roaming AP MLD an announcement. In an example, the announcement indicates that the roaming AP supports one of a link level roaming and MLD roaming within the roaming AP MLD. Based on the announcement, the non-AP MLD sends a roaming request to the roaming AP MLD, where the roaming request indicates one of the link level roaming and MLD roaming. A roaming response is received from the roaming AP MLD where the response indicates at least one new link established from the non-AP MLD to the roaming AP MLD. Based on the new link which is established, the non-AP MLD exchanges frames with the roaming AP MLD.
