摘要： Disclosed is a transmission apparatus capable of properly performing cross carrier scheduling in ePDCCHs. In this apparatus, when communication is performed using a plurality of component carriers (CCs), configuration section 102 configures a first search space as a candidate to which control information for a first CC is assigned and a second search space as a candidate to which control information for a second CC other than the first CC among the plurality of CCs is assigned, within a same allocation unit group among a plurality of allocation unit groups included in a data-assignable region within the first CC, and transmission section 106 transmits control information mapped to the first search space and control information mapped to the second search space.
