In a case of performing a carrier aggregation in which a macro cell of legacy carrier is a primary cell and a small cell of new carrier type is a secondary cell, transmissions of uplink control channel (PUCCH) converge on the uplink of the macro cell, resulting in degradation of frequency efficiency. In view of this problem, it is arranged that: the primary cell still be the macro cell; a serving cell to transmit the PUCCH be informed to terminals; and the terminals use the informed serving cell to transmit the PUCCH. |
