1. A method for transmitting Downlink Control Information (DCI), comprising:
transmitting, by a base station, the DCI to a user equipment (UE), wherein the DCI comprises following information fields: a first information field indicating a frequency resource occupied by a data resource scheduled by the DCI and a second information field indicating a time resource occupied by the data resource scheduled by the DCI; and the DCI further comprises: a seventh information field indicating a piece of or a group of pieces of Acknowledgement/Non-acknowledgement (ACK/NACK) information of an uplink Hybrid Automatic Repeated Request (HARQ), and the seventh information field existing in DCI for scheduling uplink transmission; and/or an eighth information field indicating a type of transmission and/or a type of service;
wherein the frequency resource occupied by the data resource scheduled by the DCI comprises:
a quantity of sub-carriers occupied by the data resource scheduled by the DCI; or
a quantity of sub-carriers occupied by the data resource scheduled by the DCI, and a start index of the sub-carriers;
wherein the time resource occupied by the data resource scheduled by the DCI comprises:
a quantity of symbols occupied by the data resource scheduled by the DCI, and a start symbol index of the symbols; or
a length of a Transmission Time Interval (TTI) for data transmission scheduled by the DCI, and a time domain start position of the data transmission.
