    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: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.
