Abstract

When a common search space and a user equipment-specific search space overlap with each other, and bit numbers of DCI formats transmitted in the common search space and the user equipment-specific search space, respectively are the same as each other, a mobile station apparatus identifies a type of the DCI format. When the common search space and the user equipment-specific search space overlap with each other, and a bit number of a DCI format allocated in the common search space and a bit number of a DCI format allocated in the user equipment-specific search space are the same as each other, a base station apparatus does not allocate the DCI format allocated in the user equipment-specific search space in the overlapped space, and a mobile station apparatus performs blind decoding only of the DCI format allocated in the common search space in the overlapped space.
