The present invention provides a method for transmitting control information, a base station, and a user equipment. The method includes: sending, by a base station, control information to a user equipment UE by using an enhanced physical downlink control channel EPDCCH physical resource set, wherein the base station determines, according to a mapping rule, a physical resource for sending the control information, so that the UE determines, according to the mapping rule, a carrier to which the control information is applied, where a carrier bearing the control information is the same as or different from the carrier to which the control information is applied, and the mapping rule is a correspondence between a carrier and a physical resource. The foregoing method solves problems of large control information overheads and resource waste caused by lack of configuration of an EPDCCH which can support cross-carrier scheduling in an LTE system in the prior art. |
