摘要：
In a wireless communication system in which a base station and a terminal communicate, the base station effectively transmits control information for the terminal.The base station that communicates with the terminal by using resource elements configured with OFDM symbols and subcarriers, and resource block pairs configured with a predetermined number of resource elements includes a second control channel generation unit that generates a second control channel which is transmitted by using a reference signal of an antenna port different from an antenna port of a first control channel. The second control channel is configured with predetermined E-REGs, and transmitted to the terminal, by using one or more E-CCEs. The resource block pair is configured with a predetermined number of E-REG sets. The E-REG set is configured with a predetermined number of the E-REGs. The E-REG is configured with a predetermined number of resource elements.
