A terminal for a Long Term Evolution, LTE, system, the terminal communicating with a base station , and the terminal comprising: a downlink control channel detecting unit that monitors a physical downlink control channel, PDCCH, allocated in a physical downlink control channel region and an enhanced physical downlink control channel, E-PDCCH, allocated in a physical downlink shared channel region different from the physical downlink control channel region, wherein the downlink control channel detecting unit extracts one of a plurality of individual shift values whose index is dynamically indicated by the detected E-PDCCH; a data extracting unit that, if the downlink control channel detecting unit has detected the E-PDCCH, extracts transmit data on a physical downlink shared channel, PDSCH, associated with the detected E-PDCCH; a response information generating unit that generates response information for the extracted transmit data; an uplink control channel generating unit that generates a physical uplink control channel, PUCCH, by mapping the response information to a physical uplink control channel resource which is determined by adding the extracted individual shift value and a cell specific parameter to the index of an enhanced physical downlink control channel resource in which the E-PDCCH was detected; a response transmitting unit that transmits a signal including the PUCCH; and a higher layer control information acquiring unit that acquire the cell specific parameter via a radio resource control signaling intended to each terminal, wherein some of the plurality of individual shift values are fixed values and the rest is indicated by control information notified by using a radio resource control signaling. a downlink control channel detecting unit that monitors a physical downlink control channel, PDCCH, allocated in a physical downlink control channel region and an enhanced physical downlink control channel, E-PDCCH, allocated in a physical downlink shared channel region different from the physical downlink control channel region, wherein the downlink control channel detecting unit extracts one of a plurality of individual shift values whose index is dynamically indicated by the detected E-PDCCH; a data extracting unit that, if the downlink control channel detecting unit has detected the E-PDCCH, extracts transmit data on a physical downlink shared channel, PDSCH, associated with the detected E-PDCCH; a response information generating unit that generates response information for the extracted transmit data; an uplink control channel generating unit that generates a physical uplink control channel, PUCCH, by mapping the response information to a physical uplink control channel resource which is determined by adding the extracted individual shift value and a cell specific parameter to the index of an enhanced physical downlink control channel resource in which the E-PDCCH was detected; a response transmitting unit that transmits a signal including the PUCCH; and a higher layer control information acquiring unit that acquire the cell specific parameter via a radio resource control signaling intended to each terminal, wherein some of the plurality of individual shift values are fixed values and the rest is indicated by control information notified by using a radio resource control signaling. <EOS>
