Abstract: Disclosed in the present application are a data transmission method and a device, comprising: dividing a time unit into DL areas, a time unit including at least two DL areas; notifying a terminal of the divided DL areas by means of configuration signaling. The terminal receiving the configuration signaling; according to said configuration signaling, determining DL areas into which a time unit is divided. Using the present application, defining at least two DL detection areas in a time unit, a terminal detects a downlink transmission in each detection area, and, when one is detected, performs ACK/NACK feedback in an uplink area corresponding to said downlink area. In the present invention, each downlink area has a defined feedback and scheduling relationship, respectively, by means of dividing a time unit into multiple downlink areas, thereby increasing scheduling flexibility and system resource utilization.

Abstract: A method and apparatus for transmitting downlink control information. In the present invention, transmitted downlink control information at least comprises one or more of the following information fields: a first information field used for indicating the frequency domain resources occupied by the data resources scheduled by the DCI, a second information field used for indicating the time frequency resources occupied by the data resources scheduled by the DCI, and a third information field used for indicating the scheduled N users. As the resource size occupied by the transmission resources in the frequency domain and/or in the time domain is indicated by means of the downlink control information, transmission of downlink control information can be implemented in flexible resource allocation scenarios having variable transmission time intervals.
