Method and apparatus for transmitting MTC downlink control information, base station and user equipment

A method of receiving and processing machine type communication (MTC) downlink control information (DCI), being applicable to an MTC device, the MTC device supporting searching for DCI from a target resource region, the target resource region being a control region of an original long term evolution (LTE) system, the method comprising:

• obtaining control resource configuration information from DCI received from a base station;
• determining a DCI transmission region;
• determining a target search region according to preset reference information and the DCI transmission region, wherein the preset reference information comprises a blind detection control channel element (CCE) aggregation level or physical resource configuration information sent by the base station;
• and
• detecting target DCI from the target search region according to a preset blind detection CCE aggregation level.

A machine type communication (MTC) device, comprising:

• a processor, and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• obtain control resource configuration information from downlink control information (DCI) received from a base station, and determining a DCI transmission region;
• determine a target search region according to preset reference information and the DCI transmission region, wherein the preset reference information comprises a blind detection control channel element (CCE) aggregation level or physical resource configuration information sent by the base station;
• and
• detect target DCI from the target search region according to a preset blind detection CCE aggregation level.
