摘要： 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.

摘要： 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.

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 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.

摘要： This application relates to the field of wireless fidelity technologies, and in particular, to a resource indication method, an access point, and a station. The method includes: An access point generates a PPDU, and sends the PPDU, where the PPDU comprises a preamble puncturing information field; and where when the PPDU is in non-orthogonal frequency division multiple access (non-OFDMA) transmission mode, the preamble puncturing information field is used to indicate a puncturing status of an entire bandwidth corresponding to the PPDU; when the PPDU is in an orthogonal frequency division multiple access (OFDMA) transmission mode, the preamble puncturing information field is used to indicate a puncturing status of 80 MHz corresponding to a frequency domain fragment.

摘要： This application describes resource unit indication methods, access points, and stations. In an example method, a resource unit allocation subfield in a trigger frame includes a frequency band range indication and a resource unit indication. The resource unit indication is used to indicate a multi-resource unit (MRU) allocated to a station. The frequency band range indication is used to indicate a frequency band range in which a resource unit (RU) in the MRU is located. For example, the frequency band range indication is used to indicate 80 MHz in which a smallest RU in the MRU is located.

摘要： Embodiments of this application provide a probe request and response technology between a station and a plurality of AP MLDs. If the station wants to obtain a communication parameter of a nontransmitted BSSID AP, the station may send a probe request frame to a nontransmitted BSSID AP in an MBSSID set, and a transmitted BSSID AP in the MBSSID set may reply with a probe response frame. Alternatively, if the station wants to probe a plurality of AP MLDs at a time, the station may send the probe request frame to one transmitted BSSID AP in the MBSSID set, to request the AP to reply with a communication parameter of the nontransmitted BSSID AP. The nontransmitted BSSID AP and the transmitted BSSID AP may belong to different AP MLDs. During implementation of this application, a station may obtain communication parameters of a plurality of APs of one or more AP MLDs by sending one probe request frame, to obtain communication parameters of the AP MLD on a plurality of links, thereby efficiently implementing association between the station and the AP MLD or establishing multi-link transmission between the station and the AP MLD.

摘要： A method includes an access point device that obtains a transmission opportunity (TXOP) in a wireless local area network (WLAN) and that allocates a first period in the TXOP to a non-access point device for data transmission. The access point device receives a first frame in the first period. An access address or a transmitter address of the first frame is associated with the non-access point device. The method further includes that the access point device keeps, based on the first frame, a network allocation vector (NAV) unchanged.
