Claim:
1. A terminal apparatus, comprising: a receiver structured to receive a control channel, which is snapped to a first resource defined by frequency and time in accordance with a mapping method, and to receive downlink data mapped to a second resource in accordance with downlink assignment information, wherein the control channel includes a first control channel carrying the downlink assignment information indicating the second resource to which downlink data is allocated and a second control channel carrying uplink assignment information indicating a third resource to which uplink data is allocated; and circuitry structured to detect the control channel, wherein: the mapping method is one of a localized mapping and a distributed mapping; the first control channel carrying the downlink assignment information is mapped to a first region of the first resource; the second control channel carrying the uplink assignment information is mapped to a second region of the first resource, the first region being different from the second region; and the control channel is mapped to an Orthogonal Frequency Division Multiplexing (OFDM) symbol other than at a beginning of a subframe.
