Abstract: First information received by a first MLD on a first link is used to determine whether a BSS configuration of a second link is updated. In response to the BSS configuration of the second link not being updated, the first MLD directly transmits a data frame on the switched-to second link or the second link whose status is transited, and the data frame is not transmitted until a beacon frame is received and a latest parameter of the BSS configuration is obtained on the switched-to second link or the second link whose status is transited. A waiting time occurring before the data frame is transmitted is reduced.

Abstract: This application provides a communication method and an apparatus, and relates to the field of communications technologies, to reduce a phenomenon that an acknowledge rule is violated in some scenarios. The method includes: After a receive device receives a first data unit from a transmit device through a first link, the receive device sends receiving status information of the first data unit to the transmit device through the first link, unless the first data unit meets any one of a first preset condition. The first preset condition includes: Correctly received information of the first data unit is fed back through another link, or an acknowledge policy corresponding to the first data unit is no acknowledge. The communication method in embodiments of this application is applied to a multi-link data transmission process.
