Abstract: A data unit sending or receiving method and a related apparatus that belong to the field of communication technologies are provided. 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 end of frame (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 EOF field and a second MPDU length field.

Abstract: This application provides a full-duplex self-interference weakening method and a full-duplex self-interference weakening system. The full-duplex self-interference weakening method includes: separately receiving, by a first port of a dual-polarized receive antenna and a second port of the dual-polarized receive antenna, a signal sent by a transmit antenna; and adjusting and combining the signal received by the first port of the dual-polarized receive antenna and/or the signal received by the second port of the dual-polarized receive antenna, to weaken interference caused by the transmit antenna to the dual-polarized receive antenna. The full-duplex self-interference weakening method and the full-duplex self-interference weakening system provided in this application resolve a problem that a quantity of antennas and an antenna location are limited in an existing antenna interference cancelation method.

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 comprises 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.
