Abstract:
A control signaling transmission method, a control signaling detection method, a terminal, and a base station are provided. The transmission method includes: a base station determining an enhanced Physical Downlink Control Channel (ePDCCH) resource region of the terminal in a current subframe according to at least one of multiple parameters, and transmitting control signaling to the terminal on some or all of the resources in the ePDCCH resource region. The above technical scheme can adapt to the dynamically-changing transmission capabilities of subframes, improves the transmission performance of the control signaling on an ePDCCH, increases the accuracy of the terminal in searching for the control signaling, and conserves terminal consumption. Therefore, the present document has a great industrial applicability.
