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: A method includes: A first device sends a block acknowledgment request frame to a second device. The block acknowledgment request frame is used to request the second device to send a block acknowledgment frame. The block acknowledgment frame indicates a receiving status of an access control layer protocol data unit in first transmission. The first transmission is suspended at a first moment, and the first moment is earlier than a transmission end moment when the first transmission is not suspended. The first device receives the block acknowledgment frame. The first device starts, at a second moment, to perform second transmission.

Abstract: The present disclosure relates to data communication methods and apparatuses. One example method includes when receiving a physical layer protocol data unit (PPDU), obtaining, by a network node, a basic service set (BSS) identifier in the PPDU.If the BSS identifier in the PPDU is different from a first BSS identifier and same as a second BSS identifier, the network node determines whether the PPDU meets a preset spatial reuse condition, where the first BSS identifier is an identifier of a first BSS to which the network node belongs, the second BSS identifier is an identifier of an extended BSS to which a target relay belongs, and the target relay and the network node belong to the first BSS. If the PPDU meets the preset spatial reuse condition, the network node contends for an access channel, and communicates with a station other than the target relay in the first BSS.

Abstract: A data transmission method includes sending, by a first station in a first multi-link device, a third frame. The third frame indicates the first station enables a mode of sharing a quantity of spatial streams. The mode of sharing the quantity of spatial streams is used for enabling the first station to use the shared spatial streams. A quantity of shared spatial streams is a maximum quantity of shared spatial streams supported by the first multi-link device. The data transmission method also includes receiving, by the first station, a fourth frame. The fourth frame is used for responding to the third frame.

Abstract: A method of communication includes duplication of a first field of a first content channel into a third field in a third content channel and applying a modulation and coding scheme (MCS) to only one of the first field and the third field. The first content channel is a first portion of a frame and the third content channel is a third portion of the frame. Duplication of a second field of a second content channel into a fourth field in a fourth content channel and applying a modulation and coding scheme (MCS) to only one of the second field and the fourth field. The second content channel is a second portion of a frame and the fourth content channel is a fourth portion of the frame. The first content channel and the second content channel form a first group of content channels and the third content channel and the fourth content channel form a second group of content channels. The method then transmits the frame.
