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.

What is claimed is:1. A non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform a method comprising:sending a trigger frame, wherein the trigger frame is used to:trigger an unassociated station (STA) to perform uplink data transmission, and indicate at least one available subchannel for random accessing by the unassociated STA; receiving an association request message on an available subchannel, of the at least one available subchannel, acquired by an unassociated STA; and sending a multi-user block acknowledgement frame, wherein the multi-user block acknowledgement frame includes a piece of association acknowledgement information, wherein the piece of association acknowledgement information includes a traffic identifier information, wherein the traffic identifier information comprises a dummy association identifier, and wherein the dummy association identifier indicates the piece of association acknowledgement information is acknowledgement information of the association request message. 2. The non-transitory computer-readable media according to claim 1 , wherein the dummy association identifier occupies 11 bits. 3. The non-transitory computer-readable media according to claim 1 , wherein the dummy association identifier is a special association identifier allocated by the AP. 4. The non-transitory computer-readable media according to claim 1 , wherein the traffic identifier information comprises:an acknowledgement (ACK) type, and a traffic identifier (TID); wherein the traffic identifier information is provided in a subfield that occupies two octets, and wherein the ACK type and the TID occupy a total of 5 bits of the subfield containing the traffic identifier information. 5. The non-transitory computer-readable media according to claim 1 , wherein the piece of association acknowledgement information further includes a temporary identifier of the unassociated STA allocated by the AP. 6. The non-transitory computer-readable media according to claim 1 , wherein the association acknowledgement information includes a media access control (MAC) address of the unassociated STA that is acquiring the available subchannel of the at least one available subchannel. 7. The non-transitory computer-readable media according to claim 6 , wherein the MAC address occupies a total of 6 octets. 8. The non-transitory computer-readable media according to claim 1 , wherein the trigger frame includes a temporary identifier of the at least one available subchannel allocated by the AP. 9. The non-transitory computer-readable media according to claim 7 , wherein the piece of association acknowledgement information further includes a temporary identifier of the unassociated STA allocated by the AP,wherein the traffic identifier information comprises:an acknowledgement (ACK) type, and a traffic identifier (TID); wherein the traffic identifier information is provided in a subfield that occupies two octets, wherein the ACK type and the TID occupy a total of 5 bits of the subfield containing the traffic identifier information, wherein the dummy association identifier is a special association identifier allocated by the AP and occupies 11 bits, and wherein the trigger frame includes a temporary identifier of the at least one available subchannel allocated by the AP. 10. The non-transitory computer-readable media according to claim 1 , wherein the computer instructions, when executed by the one or more processors, cause the one or more processors to further perform:sending an association response message to the unassociated STA sending the association request message, wherein the association response message carries a first association identifier (AID), wherein the first AID is allocated by the AP to the unassociated STA sending the association request message, and wherein the association response message indicates that an association between the unassociated STA sending the association request message and the AP is successfully established. 11. A non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform a method comprising:receiving a trigger frame sent by an access point (AP), wherein the trigger frame is used to:trigger an unassociated station (STA) to perform uplink data transmission, and indicate at least one available subchannel for random accessing by the unassociated STA; performing random accessing to acquire an available subchannel; sending an association request message on the available subchannel, of the at least one available subchannel, acquired by an unassociated STA; receiving a multi-user block acknowledgement frame, wherein the multi-user block acknowledgement frame includes a piece of association acknowledgement information, wherein the piece of association acknowledgement information includes a traffic identifier information, wherein the traffic identifier information comprises a dummy association identifier, and wherein the dummy association identifier indicates the piece of association acknowledgement information is acknowledgement information of the association request message. 12.
