Abstract: Disclosed is an integrated circuit to control a process for a terminal. The process includes: receiving downlink control information and downlink data; determining, based on the downlink control information and an offset, a physical uplink control channel (PUCCH) resource used for transmission of a response signal for the downlink data; and transmitting the response signal using the determined PUCCH resource. A first offset is used as the offset when the terminal is configured in a coverage enhancement mode, in which the response signal is allowed to be transmitted repeatedly for one of plural repetition levels in a plurality of subframes, where the first offset is configured for each of the plural repetition levels. The first offset is different from a second offset, which is used when the terminal is not configured in the coverage enhancement mode.

Abstract: A wireless communication terminal apparatus wherein CoMP communication can normally be performed without increasing the overhead of an upstream line control channel. In this apparatus, a spreading unit (214) primarily spreads a response signal by use of a ZAC sequence established by a control unit (209). A spreading unit (217) secondarily spreads the response signal, to which CP has been added, by use of a block-wise spread code sequence established by the control unit (209). The control unit (209) controls, in accordance with sequence numbers and a hopping pattern established therein, the circular shift amount of the ZAC sequence to be used for the primary spread in the spreading unit (214) and the block-wise spread code sequence to be used for the secondary spread in the spreading unit (217). The hopping pattern established in the control unit (209) is a hopping pattern common to a plurality of base stations that CoMP-receive the response signal.

Abstract: Provided are a wireless communication terminal device and a power allocation method, wherein transmission channel quality information, regarding a Pcell having a high probability that UCI is multiplied therein, can be accurately estimated by an SRS having high priority in power allocation, and an eNB can instruct appropriate transmission power to an UL channel which transmits the subsequent UCI. A power scaling detection unit detects whether or not a total transmission power value of the UL channels transmitted by the plurality of CC exceeds the maximum transmission power specific to the UE. When a plurality of SRS are simultaneously transmitted using a Pcell and a Scell, and power scaling occurs, a power scaling control unit performs power allocation so that transmission power of the SRS of the Pcell has the higher priority than that of the SRS of the Scell.
