Disclosed is a method for transmitting and receiving control information. The method for transmitting control information according to the present invention, in a mobile communication system in which a control channel region and a data channel region are separated from each other, comprises the steps of: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. According to the present invention, a capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.
A method in which a base station transmits downlink control information to a terminal in a mobile communication system where a Physical Downlink Control Channel (PDCCH) area is divided from a Physical Downlink Shared Channel (PDSCH) area, the method comprising:
