Enhanced acknowledgment and power saving for wireless communications

A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

• determining a multi-user (MU) multiple-input multiple-output (MIMO) frame associated with a MU-MIMO group;
• determining a first indication included in the MU-MIMO frame, wherein the first indication is associated with a first station device of the MU-MIMO group, and wherein the first indication indicates a first time slot assigned to the first station;
• determining a second indication included in the MU-MIMO frame, wherein the second indication is associated with a second station device of the MU-MIMO group, and wherein the second indication indicates a second time slot assigned to the second station, wherein the first indication is different from the second indication, and wherein the first time slot is different from the second time slot, and wherein the first station device is different from the second station device;
• causing to send the MU-MIMO frame to the MU-MIMO group;
• identifying a first acknowledgment from the first station device based on the first time slot;
• and
• identifying a second acknowledgement from the second station device based on the second time slot.
