A method for improving multiple-user (MU) multiple-input-multiple-output (MIMO) acknowledge (ACK) protocol efficiency includes: receiving a sounding frame from a device, sending a feedback response, which includes quantized channel state information (CSI) to the device, receiving an MU physical-layer protocol data unit (PPDU) frame from the device, and in response to receiving the MU PPDU frame, sending an ACK frame to the device without receiving a polling frame prior to the ACK frame.
