The application provides a method and equipment for transmitting control information, wherein the method comprises the steps that a first network device sends configuration information to a terminal device, the configuration information is used for indicating the terminal device to detect first control information on a first carrier, and detect second control information on a second carrier, and the first control information and the second control information are both control information of data scheduling of the second carrier; the first network device transmits at least one of the first control information and the second control information. Therefore, the configuration information is sent by the network equipment, and for data scheduling of one carrier, the terminal equipment detects both the cross-carrier scheduling cell and the local carrier scheduling cell. The problem that only the control information on the scheduling data carrier is detected in the prior art is solved, the problem of resource conflict of a plurality of control information of the same terminal equipment is avoided, the terminal equipment can accurately acquire the control information sent by each transmission point, and the network performance is improved.
