Embodiments of the present invention provide a method for transmitting a downlink control signal, a base station, and a user equipment. The method includes: mapping, by a base station according to an order of OFDM symbols used by an E-PDCCH of a user equipment UE, the E-PDCCH sequentially to resource elements used to transmit the E-PDCCH in each OFDM symbol; and sending, by the base station, the E-PDCCH to the UE by using the resource elements, where the E-PDCCH and a PDSCH invoked by the E-PDCCH are frequency-division multiplexed. In the present invention, the E-PDCCH can be mapped, according to an order of OFDM symbols used by an E-PDCCH of a UE, sequentially to resource elements used to transmit the E-PDCCH in each OFDM symbol, so that different control channel elements of E-PDCCHs at different aggregation levels will not include a same E-PDCCH modulation symbol, thereby avoiding that the UE judges a start position of the E-PDCCH incorrectly. |
