Abstract  Abstract

PROBLEM TO BE SOLVED: To restrain wasteful bandwidth reduction of PUSCH by increasing utilization efficiency of ACK/NACK resources, while circumventing conflict of the ACK/NACK, in a system where control information of E-PDCCH is transmitted.SOLUTION: A radio communication terminal has reception means for receiving control information by using a PRB set constituting an E-PDCCH, where the PRB set includes one or more than one PRBs, control means for detecting which PRB set out of preset multiple PRB sets is received, and determining the resource of PUCCH for mapping the ACK/NACK, based on the value of an ARI contained in the E-PDCCH of the received PRB set and the detected PRB set, and transmission means for transmitting the ACK/NACK by using the determined resource of the PUCCH. The ARI is a value not relying upon the number of eCCE constituting the PRB set received by the E-PDCCH, and can take multiple numbers for the received PRB set.SELECTED DRAWING: Figure 11
