The present invention discloses a control information transmission method, a user equipment, and a base station. The method includes: obtaining a data channel transmission mode configured by a base station; determining a downlink control information DCI format set corresponding to the transmission mode, where the DCI format set includes a first DCI format, and the first DCI format includes single-codeword control information; and detecting, according to the DCI format set, control signaling sent by the base station and corresponding to the DCI format set. The user equipment includes a first obtaining module, a first determining module, and a detecting module. The base station includes a configuring module, a first determining module, and a first sending module. Because the data channel transmission mode corresponds to at least two transmission manners, the control information transmission method, the user equipment, and the base station in embodiments of the present invention can enhance a control channel, reduce overhead of the control channel, improve system scheduling efficiency and flexibility, overcome the congestion problem of the control channel, and improve the utilization rate of control channel resources of a system. |
