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. To this end, a wireless communications terminal is disclosed. The Terminal comprising: a reception unit that receives control signals including an ACK/NACK indicator that takes one of four possible values, via an enhanced physical downlink control channel; a control unit that determines, on the basis of the ACK/NACK indicator, a resource number to transmit an ACK/NACK signal using a dynamic ACK/NACK resource which is dynamically allocated to it, wherein the resrouce numbers for a first and a second value of the ACK/NACK indicator are consecutive numbers; and a transmission unit that sends the ACK/NACK signals using the dynamic ACK/NACK resource having the determined number. |
