1. An integrated circuit controls a communication apparatus, the integrated circuit comprising:
a mapping circuitry which, in operation, maps downlink control information to resources by:
selectively mapping the downlink control information to resources of a first resource region and a second resource region included in a first type of subframe, the first resource region being available for a downlink control channel and a downlink data channel and the second resource region being available for the downlink control channel;
selectively mapping the downlink control information to resources of the second resource region included in a second type of subframe, the second type of subframe having a gap period between a downlink period and an uplink period in time division duplex (TDD); and
a transmitting circuitry which, in operation, transmits the mapped downlink control information, wherein a terminal apparatus that receives the transmitted downlink control information does not blind-decode the first resource region in the second type of subframe,
wherein the mapping circuitry configures whether to map the downlink control information to the resources of the first resource region and the second resource region included in the first type of subframe, or to map the downlink control information to the resources of the second resource region included in the second type of subframe, per subframe.
