<P>PROBLEM TO BE SOLVED: To disclose a method and system for improving responsiveness in exchanging management and control frames in a wireless local area network. <P>SOLUTION: An initiator sends a frame (action, management, control or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses a wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of a feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet. <P>COPYRIGHT: (C)2011,JPO&INPIT |
