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: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.

Abstract: An antenna channel sounding method, an apparatus, and a storage medium are provided. A first communication apparatus sends a first frame and a first physical layer protocol data unit (PPDU) to a second communication apparatus. The first frame includes first indication information for indicating the second communication apparatus to perform transmit antenna channel sounding. The first PPDU is a null data packet (NDP). The first PPDU includes a first identifier field indicating an identifier of a first transmit antenna set. In this way, the second communication apparatus can determine a correspondence between a transmit antenna channel sounding result corresponding to a received PPDU and an identifier of a transmit antenna set, and can determine an identifier of a transmit antenna set selected based on one or more transmit antenna channel sounding results. This can perform antenna selection based on the antenna channel sounding results in the large-scale antenna scenario.
