Abstract

According to one discourse of the present specification, a method for receiving information by a machine type communication (MTC) device is provided. The method of receiving the information may comprise the steps of: monitoring cell-specific control information within a common search space; and monitoring MTC device-specific control information within a UE-specific search space. Here, a resource region in which the common search space (CSS) is located and a resource region in which the UE-specific search space (USS) is located may be configured not to overlap each other.

First claim

1 . A method for receiving information by a machine type communication (MTC) device, the method comprising:
monitoring cell-specific control information within a common search space; and monitoring MTC device-specific control information within a UE-specific search space, wherein a resource region in which the common search space (CSS) is located and a resource region in which the UE-specific search space (USS) is located are configured not to overlap each other.

2 . The method of claim 1 , wherein the resource region is a subframe unit.

3 . The method of claim 1 , wherein the resource region is any one of a control channel element (CCE) unit, a resource element group (REG) unit, and a resource element (RE) unit.

4 . A method for receiving information by a machine type communication (MTC) device, the method comprising:
determining a common search space (CSS) where cell-specific control information is to be monitored; determining a UE specific search space (USS) where UE-specific control information is to be monitored; and selectively monitoring only any one search space when all or some of radio resources of the common search space (CSS) and radio resources of the UE-specific search space (USS) overlap with each other.

5 . The method of claim 4 , wherein the monitoring includes prioritizing the common search space (CSS) to the UE-specific search space (USS), and monitoring the cell-specific control information within the common search space.

6 . The method of claim 4 , wherein the monitoring includes
prioritizing the UE-specific search space (USS) to the common search space (CSS), and monitoring the UE-specific control information within the UE-specific search space (USS).

7 . The method of claim 4 , wherein control information within a search space other than a search space selected to be monitored is punctured on the radio resource.

8 . The method of claim 4 , wherein in the monitoring, when a PDCCH masked with a system information-radio network temporary identifier (SI-RNTI) is present in the radio resource, only the common search space (CSS) is monitored on the radio resource.

9 . A machine type communication (MTC) device comprising:
a processor configured to determine a common search space (CSS) where cell-specific control information is to be monitored and determine a UE-specific search space (USS) where UE-specific control information is to be monitored; and a transceiving unit configured to selectively monitor only any one search space when all or some of radio resources of the common search space (CSS) and radio resources of the UE-specific search space (USS) overlap with each other.

10 . The MTC device of claim 9 , wherein the processor is configured to prioritize the common search space (CSS) to the UE-specific search space (USS) and thereafter, control the transceiving unit to monitor the cell-specific control information within the common search space (CSS).

11 . The MTC device of claim 9 , wherein the processor is configured to prioritize the UE-specific search space (USS) to the common search space (CSS) and thereafter, control the transceiving unit to monitor the UE-specific control information within the UE-specific search space (USS).

12 . The MTC device of claim 9 , wherein control information within a search space other than a search space selected to be monitored is punctured on the radio resource.

13 . The MTC device of claim 9 , wherein the processor controls the transceiving unit to monitor only the common search space (CSS) on the radio resource when a PDCCH masked with a system information-radio network temporary identifier (SI-RNTI) is present in the radio resource, only the common search space (CSS) is monitored on the radio resource.
