Claim 15:
16. A non-access point (non-AP) multi-link device (MLD) that includes power save operation, wherein a plurality of links are established between the non-AP MLD and an AP MLD, the non-AP MLD comprising:
a processor configured to set a QoS capability for a first 802.11 access category to a first state for all links of the plurality of links that the non-AP MLD operates;
a transmitter configured to transmit a first management frame to the AP MLD, wherein the first management frame is used to request a multi-link setup with the AP MLD, and wherein the first management frame includes a first element that comprises the setting of the QoS capability for the first 802.11 access category; and
a receiver configured to:
receive a second management frame from the AP MLD, wherein the second management frame includes information for an association ID (AID) that corresponds to the non-AP MLD, wherein the AID is assigned to the non-AP MLD regardless of the number of links in the plurality of links; and
receive a third management frame from the AP MLD, wherein the third management frame comprises a partial virtual bitmap and a bit in the partial virtual bitmap corresponds to the AID is set to indicate if the first state is a nondelivery-enabled access category and the AP MLD has buffered buffer units (BU) of the first 802.11 access category for the non-AP MLD.
