Embodiments of the present invention provide a control information enhanced transmission method, a user equipment, a base station, and a communications system. The method comprises: determining first parameters of control information enhanced transmission, and performing enhanced transmission of control information according to the first parameters. Between a base station and a UE, a kth subframe after a last subframe of the control information enhanced transmission may be preset as a start subframe of PDSCH enhanced transmission, and a jth subframe after the last subframe of the control information enhanced transmission may be preset as a start subframe of PUSCH enhanced transmission, start subframes for control information enhanced transmission are preset, and the subframes may also be radio frames. In this manner, the UE can determine the number of repetitions of the control information enhanced transmission according to the preset start subframes, preset radio frames and one or more of the first parameters. Accordingly, the user equipment can accurately determine a last subframe and/or radio frame occupied by control information, and further, accurately determine a start time point of receiving the retransmitted PDSCH or a start time point of retransmitting the PUSCH, and performance of the PDSCH or the PUSCH is ensured, the start time point comprising a start subframe and/or a start radio frame. |
