Abstract
Association procedure in 802.11 networks is bandwidth consuming because the management frames are sent in the low bitrate Single User mode. Multi-user operations are not available for unassociated stations because they are not assigned association identifiers. The present invention proposes to provide temporary AIDs to unassociated stations sending a frame to the AP, wherein the temporary AIDs are conveyed by a multi-station block acknowledgment. In an efficient scenario for station association, unassociated stations randomly access tone sets of a short feedback procedure. Based on the feedback responses, the AP subsequently provides MU UL RUs for the unassociated station to send a first management frame. Subsequently, the temporary AID may be used to schedule further MU UL RUs and to provide response in MU DL transmissions.
