摘要

An association establishment method and apparatus, for carrying out the method are described. The association establishment method includes broadcasting, by an access point (AP), a trigger frame, wherein the trigger frame is used to trigger one or more unassociated stations STAs to perform uplink data transmission and indicate one or more available subchannels for random accessing of the unassociated STAs. The method further includes receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs. Thereafter, the AP broadcasts a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message.

說明書

With reference to the seventh aspect, in a second possible implementation of the seventh aspect, the association acknowledgement information further includes a MAC address of the second STA.

With reference to any one of the seventh aspect to the second possible implementation, in a third possible implementation of the seventh aspect, a special traffic identifier TID or all 4 bits of a TID in the association acknowledgement information indicates or indicate a quantity of second STAs to which the AP sends acknowledgement requests by using a same piece of association acknowledgement information.

With reference to any one of the seventh aspect to the second possible implementation, in a fourth possible implementation of the seventh aspect, the association acknowledgement information further includes a statistical identifier, and the statistical identifier indicates a quantity of second STAs to which the AP sends acknowledgement requests by using a same piece of association acknowledgement information.

With reference to the fourth possible implementation of the seventh aspect, in a fifth possible implementation of the seventh aspect, the statistical identifier is located after per traffic identifier information in the association acknowledgement information.

With reference to the fourth possible implementation of the seventh aspect, in a sixth possible implementation of the seventh aspect, the statistical identifier occupies a bit reserved in block acknowledgement starting sequence control in the association acknowledgement information.

According to an eighth aspect, an embodiment of the present invention provides an association establishment apparatus, where the apparatus is a first station STA, and includes:
