Abstract: 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.

Abstract: This application discloses a data unit sending or receiving method, and a related apparatus; and belongs to the field of communication technologies. In this solution, a transmit end sends a first aggregated media access control protocol data unit A-MPDU and determines an MPDU that needs to be retransmitted in the first A-MPDU. The MPDU that needs to be retransmitted is included in a first A-MPDU subframe in the first A-MPDU. The first A-MPDU subframe includes a first MPDU delimiter, and the first MPDU delimiter includes a first EOF field and a first MPDU length field. The transmit end sends a second A-MPDU, where the second A-MPDU includes a second A-MPDU subframe, the second A-MPDU subframe includes the MPDU that needs to be retransmitted and a second MPDU delimiter, and the second MPDU delimiter includes a second end of frame EOF field and a second MPDU length field.

Abstract: This application provides a communication method and apparatus, to resolve a problem that retransmitted MPDUs with different RVs cannot be transmitted in a same transmission process, and improve data transmission efficiency. The communication method and apparatus may be applied to a data retransmission process between any two nodes in a Wi-Fi system. The method includes: When a PPDU sent by a first node includes one or more retransmitted MPDUs, the first node may include, in the PPDU, RV indication information used to indicate an RV of each retransmitted MPDU, so that a second node receives each retransmitted MPDU based on the RV indication information.
