  • Publication number: 20210120602
    Abstract: Multi-link device (MLD) devices and transitions are described. The MAC addresses of the AP MLD and non-AP MLD are used to generate keys for different fast transitions (FT) between a non-AP MLD and an AP MLD. In an FT initial mobility domain operation, the AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S0KH-ID and S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in a single FT 4-way handshake. In a fast MLD transition to an AP MLD in the same ESS, the other AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in an FTE.

    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.
