Claim 18:
19. The MTC device according to claim 17, wherein the preset reference information comprises the physical resource configuration information sent by the base station, and the processor is further configured to:
determine a preset resource mapping mode of a region to be detected according to the physical resource configuration information, wherein the region to be detected comprises the DCI transmission region or a mapping region of the DCI transmission region;
in response to that the preset resource mapping mode is a first mapping mode, determine the region to be detected excluding the target resource region as the target search region; and
in response to that the preset resource mapping mode is a second mapping mode, determine a valid region of the entire region to be detected as the target search region, wherein the valid region is a region of the region to be detected excluding a CRS resource;
wherein the first mapping mode is configured to map a target physical resource in a data region of the original LTE system, and the target physical resource carries DCI of the MTC device; and
the second mapping mode is configured to map the target physical resource in a valid region of a subframe, and the valid region of the subframe is a time/frequency region excluding a CRS resource in the subframe.
