1. A method of transmitting control signaling comprising:
- a base station instructing a user equipment via signaling to switch to an enhanced physical downlink control channel mode, wherein the signaling instructs the user equipment operating in the enhanced physical downlink control channel mode to detect control signaling over a resource corresponding to an enhanced physical downlink control channel and a resource corresponding to a common search space of a physical downlink control channel, PDCCH; and
the base station transmitting the control signaling to the user equipment over the resource corresponding to the enhanced physical downlink control channel and the resource corresponding to the common search space upon reception of a feedback message of the user equipment,wherein the feedback message notifies the base station that the user equipment has switched to the enhanced physical downlink control channel mode.

Abstract
Provided in an embodiment of the present invention are a control signaling transmission method, base station, terminal and system, comprising: when the terminal operates in an E-PDCCH mode, the base station may transmit a control signaling to the terminal via a resource corresponding to the E-PDCCH and a resource corresponding to common search space; that is, in the E-PDCCH mode, the control signaling transmission method on the resource corresponding to the common search space is maintained, thus providing an effective mechanism to transmit the control signaling of the terminal operating in the E-PDCCH mode.

7. A base station comprising:
-
a first sending module configured to instruct a user equipment via signaling to switch to an enhanced physical downlink control channel mode, wherein the signaling instructs the user equipment operating in the enhanced physical downlink control channel mode to detect control signaling over a resource corresponding to an enhanced physical downlink control channel and a resource corresponding to a common search space of a physical downlink control channel, PDCCH; a reception module configured to receive a feedback message of the user equipment, wherein the feedback message notifies the base station that the user equipment has switched to the enhanced physical downlink control channel mode; and a signaling transmission module configured to transmit the control signaling to the user equipment over the resource corresponding to the enhanced physical downlink control channel and the resource corresponding to the common search space after the reception module receives the feedback message. - View Dependent Claims (8, 9, 10, 11, 12)

13. A user equipment comprising:
-
a first reception module configured to receive signaling of a base station to instruct the user equipment to switch to an enhanced physical downlink control channel mode, wherein the signaling instructs the user equipment operating in the enhanced physical downlink control channel mode to detect control signaling over a resource corresponding to an enhanced physical downlink control channel and a resource corresponding to a common search space of a physical downlink control channel, PDCCH; a first sending module configured to send a feedback message to the base station, wherein the feedback message notifies the base station that the user equipment has switched to the enhanced physical downlink control channel mode, and a second reception module configured to receive the control signaling transmitted by the base station over the resource corresponding to the enhanced physical downlink control channel and the resource corresponding to the common search space of the physical downlink control channel. - View Dependent Claims (14, 15, 16, 17, 18)
