Communication apparatus and method that can promptly and efficiently perform decoding/processing of a PDCCH that is related to a search space |
摘要 |
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: performs monitoring of a physical downlink control channel in an extension search space in accordance with an instruction from the base station apparatus. |

1. A mobile station apparatus that is configured to communicate with a base station apparatus by using a plurality of cells, the mobile station apparatus comprising:
a reception circuitry configured to and/or programmed to perform detecting of Downlink Control Information with CRC (cyclic redundancy check) bits scrambled by C-RNTI (cell-radio network temporary identity) in a first search space which is commonly determined for mobile station apparatuses in a first cell and a second search space which is a mobile station apparatus specific search space determined based on at least the C-RNTI, and to perform detecting of Downlink Control Information with the CRC bits scrambled by RNTI which is different from the C-RNTI in a third search space which is different from the first search space and the second search space and is commonly determined for mobile station apparatuses in a second cell which is a specific cell within the plurality of cells, wherein the detection of the Downlink Control Information with CRC bits scrambled by the C-RNTI in the first search space and the second search space and the detection of the Downlink Control Information with the CRC bits scrambled by the RNTI are performed in a same subframe. |
