Claim Text:
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.
