Abstract
A signal including control information is enabled to be transmitted and received efficiently between a base station device and a mobile station device. A plurality of physical resource block pairs are configured as control channel regions which are regions in which there is a probability of the control channels being mapped. First components are configured by resources divided from one of the physical resource block pair. The control channel is configured from an aggregation of one or more first components. An antenna port used to transmit the first component is selected from a plurality of kinds of combinations. When one combination is selected from the plurality of kinds of combinations, there is provided a second radio network resource control unit that selects the combination on the basis of at least one of parameters for determining a C-RNTI number assigned to the mobile station device, N1 which is a parameter unique for a terminal, and an initial value Cinit of a series of UE-specific RSs used for a second PDCCH.
