<p>The present invention relates to a method for improving responsiveness in exchanging management and control frame in a wireless local area network (LAN) and a system thereof. An initiator transmits a frame (action, management, control, or data frame) to a responder. If the frame is accurately received, the responder sends a response frame to the initiator, instead of directly transmitting an acknowledgement (ACK) packet. It is desirable for the responder to access a wireless medium and send the response frame in a short inter-frame spacing (SIFS). With this method, a long delay associated with the competition for a wireless medium to transmit the response frame can be avoided and, therefore, the responsiveness and timeliness of feedback mechanism are remarkably improved. The response frame is piggybacked on or integrated with another packet.
