  • Patent number: 12262431
    Abstract: During association between an access point (AP) multi-link device (MLD) and a non-AP MLD, the non-AP MLD indicates a first capability allocation of a first combination of affiliated stations for a first combination of enabled links on the non-AP MLD, and indicates a second capability allocation of a second combination of affiliated stations for a second combination of enabled links on the non-AP MLD. For example, the first combination of affiliated stations and the second combination of affiliated stations have different numbers of stations in the non-AP MLD, and the first combination of enabled links and the second combination of enabled links have different numbers of enabled links. Hence, during the association between the non-AP MLD and the AP MLD, capabilities of different non-AP station combinations corresponding to different enabled link combinations supported by the non-AP MLD are signaled to the AP MLD.
