1. A communication system comprising:
a base station includes a transmitting circuitry which, in operation, transmits downlink control information to a terminal apparatus; and
wherein the terminal apparatus includes:
a receiver which, in operation, receives the downlink control information that is:
selectively mapped 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, the second resource region being available for the downlink control channel; or
selectively mapped 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) communications; and
a decoder which, in operation, identifies both of the first resource region and the second resource region or only the second resource region as a region for decoding, and decodes the identified first and second resource regions or the identified second resource region to obtain the downlink control information,
wherein whether to decode both the first resource region and the second resource region or to decode only the second resource region is configured per subframe.
