Abstract
The purpose of the present invention is to avoid ACK/NACK collision in a system in which E-PDCCH control information is transmitted, increase the utilization efficiency of ACK/NACK resources, and suppress unnecessary PUSCH band reduction. A wireless communications terminal having a configuration comprising: a reception unit that receives control signals including ACK/NACK indexes, via an expanded physical downlink control channel; a control unit that determines, on the basis of the ACK/NACK indexes, whether to use a dynamically allocated dynamic ACK/NACK resource or a specified resource specified beforehand, to send downlink data ACK/NACK signals; and a transmission unit that sends the ACK/NACK signals using the dynamic ACK/NACK resource or the specified resource, as determined.
