Abstract
A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit () sets a search space having a plurality of allocation candidates, in both regions. An allocation unit () allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.
