Claim of US Patent No. 10,219,276

1. An integrated circuit comprising:control circuitry, which, in operation:
configures a common search space for a plurality of terminals that communicate with a communication apparatus using a plurality of component carriers, and configures a specific search space for each of the plurality of terminals;
assigns control information including resource assignment information to a control channel element (CCE) in the common search space or the specific search space; and
transmitting circuitry, which, in operation, controls transmission of the control information to one or more of the plurality of terminals,
wherein:
the control information, a format of which is common to the plurality of terminals and which includes a carrier indicator that indicates each of the plurality of component carriers, is assigned to the CCE in the specific search space configured in a primary component carrier among the plurality of component carriers; and
the control information, a format of which is common to the plurality of terminals and which includes no carrier indicator, is assigned to the CCE in the common search space configured in a primary component carrier among the plurality of component carriers.
