Abstract
Multi-link device (MLD) security association (SA) query and query response procedures are described. Any of the links between an access point (AP) MLD and a non-AP MLD may be used to initiate association, reassociation, or disassociation procedures using the SA query requests and responses. The SA query request or response from one of the stations (STAs) associated with the MLD is sent to a corresponding linked one of the STAs associated with the other MLD. The SA request or response is addressed to the other MLD rather than the STA of the other MLD. Retry timeouts and maximum timeouts for resending SA query requests are set by the AP MLD and the same across each of the links.
