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.

Abstract: Disclosed are a data transmission method, a terminal, and a base station. Determined is that a TB needs to be divided into M CBG; grouping, according to a preset grouping scheme, multiple CB produced when the one TB is code block segmented, thus diving the one TB into the M CBG; and transmitting data according to the M CBG, where M is a positive integer. The technical solution of the present invention solves the technical problem of low data transmission efficiency and low resource utilization rate in an LTE system found in the prior art.

Abstract: Disclosed in the present application are a data transmission method and device. The method comprises: a base station sends a signaling notification to a terminal, so that the terminal determines, according to the signaling notification, whether a pilot signal of data transmitted using a second transmission time interval exists within a first transmission time interval, wherein the first transmission time interval is shorter than the second transmission time interval, or the priority of a service carried by the first transmission time interval is higher than the priority of a service carried by the second transmission time interval, there is a resource overlap between the first transmission time interval and the second transmission time interval, and the terminal using the first transmission time interval for data transmission knows a pilot signal location of the data transmitted using the second transmission time interval; and the base station performing transmission according to a pilot signal resource location of the second transmission time interval. The present application can ensure that a receiving end for other service transmissions can use a pilot signal for data demodulation, thereby avoiding the waste of resources caused by the destruction of the pilot signal.
