Claim 14:
15. The method according to claim 13, wherein the preset reference information comprises the physical resource configuration information sent by the base station, and determining the target search region according to the preset reference information and the DCI transmission region comprises:
determining 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, determining 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, determining 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 the 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.
