1. A method for power save operation by a non-access point (non-AP) multi-link device (MLD), wherein a plurality of links are established between the non-AP MLD and an AP MLD, the method comprising:
setting, by the non-AP MLD, 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;
transmitting, by the non-AP MLD, 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;
receiving, by the non-AP MLD, 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
receiving, by the non-AP MLD, 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 corresponding 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.
