Abstract

A communication system, a mobile station apparatus, a base station apparatus, and a processing method are provided that can perform decoding processing of a PDCCH related to a search space efficiently, and can perform communication promptly. A mobile station apparatus for performing communication with a base station apparatus in a mobile communication system: perform monitoring of a physical downlink control channel in an extension search space in accordance with an instruction from the base station apparatus.

Claims

1-6. -6. (canceled)

7. A mobile station apparatus for performing communication with a base station apparatus in a mobile communication system, wherein

the mobile station apparatus:

performs monitoring of a physical downlink control channel in an extension search space in accordance with an instruction from said base station apparatus, where the extension search space is different from a common search space commonly determined for mobile station apparatuses in a cell and an UE-specific search space determined for each mobile station apparatus.

8. A base station apparatus for performing communication with a mobile station apparatus in a mobile communication system, wherein

the base station apparatus instructs said mobile station to perform monitoring of a physical downlink control channel in an extension search space, where the extension search space is different from a common search space commonly determined for mobile station apparatuses in a cell and an UE-specific search space determined for each mobile station apparatus.

9. A method for processing a mobile station apparatus in a mobile communication system, wherein

said mobile station apparatus:

performs monitoring of a physical downlink control channel in an extension search space in accordance with an instruction from the base station apparatus, where the extension search space is different from a common search space commonly determined for mobile station apparatuses in a cell and an UE-specific search space determined for each mobile station apparatus.

10. A method for processing a base station apparatus in a mobile communication system, wherein

said base station apparatus instructs said mobile station to perform monitoring of a physical downlink control channel in an extension search space, where the extension search space is different from a common search space commonly determined for mobile station apparatuses in a cell and an UE-specific search space determined for each mobile station apparatus.
