Abstract
A wireless communication terminal capable of increasing the utilization efficiency of ACK/NACK resources and suppressing unnecessary PUSCH band reduction while avoiding ACK/NACK collision. The wireless communication terminal has a configuration provided with: a reception unit for receiving a control signal including ARI via an E-PDCCH set from among one or a plurality of E-PDCCH sets; a control unit for determining an offset value indicated by the ARI on the basis of whether or not a resource region that may be taken by a dynamic ACK/NACK resource corresponding to the E-PDCCH set that has received the control signal and a resource region that may be taken by a dynamic ACK/NACK resource corresponding to another E-PDCCH set overlap, and imparting an offset to the ACK/NACK resource according to the value of the ARI; and a transmission unit for transmitting the ACK/NACK signal using the determined ACK/NACK resource.
