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 communication field, and in particular, to a communication method and apparatus applicable to a multi-link device. The approach generates, by a first access point (AP) of a first access point multi-link device (AP MLD), first information that indicates whether a key basic service set (BSS) parameter corresponding to at least one AP of the first AP MLD changes. In turn, the first AP sends the first information to a first station multi-link device (STA MLD).

Abstract: Embodiments of the present disclosure disclose example data communication methods and apparatuses. One set of operations performed by the example solutions includes sending a preset frame to an access point (AP) associated with a data communication apparatus, wherein the data communication apparatus and the AP belong to a first basic service set (BSS) having a first BSS identifier, and the preset frame comprises a second BSS identifier that identifies a second BSS. A physical layer protocol data unit (PPDU) is sent, wherein the PPDU comprises a target BSS identifier. Receiving a frame from the AP is stopped in response to the target BSS identifier being the same as the second BSS identifier and different from the first BSS identifier, as well as a preset condition being met.
