TRANSMISSION DEVICE, RECEIVING DEVICE, TRANSMISSION METHOD, AND RECEIVING METHOD

摘要

Provided is a transmission device capable of performing cross carrier scheduling appropriately in ePDCCH. In this transmission device, when communication is performed with a plurality of component carriers (CCs), a setting section (102) specifies a first search space and a second search space within the same allocation unit group among a plurality of allocation unit groups included in a data allocatable area in the first CC, said first search space being a candidate to which control information for a first CC is allocated, and said second search space being a candidate to which control information for a second CC other than the first CC among the plurality of CCs is allocated. A transmitter (106) sends control information mapped to the first search space and the second search space.
