Abstract
Data transmission method and device are provided. The method includes: determining a portion of a plurality of links as dedicated link, and the other portion of the plurality of links as ordinary link, wherein the dedicated link is configured to transmit control frames which include ordinary control frames and dedicated control frames, and the ordinary link is configured to transmit data frames and ordinary control frames; determining links for control frames to be transmitted and data frames to be transmitted; and when the dedicated link or the ordinary link obtains a transmission opportunity, transmitting a control frame or a data frame at a head of a queuing list of the link. By configuring the dedicated link, transmission efficiency of the control frames may be improved, compatibility with existing systems is relatively good, and complexity of design is relatively low.
