The invention discloses a method for transmitting control information,
user equipment and a
base station. The method comprises the following steps of: acquiring a transmission mode of a
data channel configured by the
base station; determining a downlink control information DCI format set corresponding to the transmission mode, wherein the DCI format set comprises a first DCI format, and the first DCI format comprises single
code word control information; and detecting a control signaling which is sent by the
base station and corresponds to the DCI format set according to the DCI format set. The
user equipment comprises a first acquisition module, a first determination module and a detection module. The base
station comprises a configuration module, a first determination module and a first sending module. By the method for transmitting the control information, the
user equipment and the base
station, the transmission mode of the
data channel at least corresponds to two transmission
modes, so that the
control channel can be enhanced, the expense of the
control channel is reduced, and the
system scheduling efficiency and flexibility are improved; and moreover, the problem of blocking of the
control channel can be solved, and the
utilization rate of control channel resources of a
system can be increased.
