Abstract: Provided are a method and device for transmitting downlink control information. The method comprises: according to a predefined condition, the downlink control information carried on an ePDCCH onto at least one PRB pair, the predefined condition comprising at least one of: an ePDCCH aggregation level, a subframe cyclic prefix type, a format of downlink control information carried on the ePDCCH, an ePDCCH transmission mode, and mapping mode indication information; and the downlink control information carried on the at least of PRB pairs is transmitted. By mapping according to one or more predefined conditions, the present disclosure achieves mapping from the ePDCCH to the physical resource pair, and ensures the ePDCCH to obtain frequency domain diversity gain and scheduling gain.
