1. A method of transmitting machine type communication (MTC) downlink control information (DCI), being applicable to a base station, comprising:
determining a DCI transmission region configured for an MTC device;
generating and sending control resource configuration information to the MTC device;
determining an information detection capability of the MTC device in the DCI transmission region, wherein the information detection capability indicates whether the MTC device supports searching for DCI from a target resource region, and the target resource region is a control region of an original long term evolution (LTE) system;
mapping a target physical resource in the DCI transmission region according to the information detection capability and a preset resource mapping mode, wherein the target physical resource carries the DCI of the MTC device; and
transmitting the DCI to the MTC device through the target physical resource mapped in the DCI transmission region.
