    Abstract: 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. A wireless communications terminal having a configuration comprising: a reception unit that receives control signals including ACK/NACK indexes, via an expanded physical downlink control channel; a control unit that determines, on the basis of the ACK/NACK indexes, whether to use a dynamically allocated dynamic ACK/NACK resource or a specified resource specified beforehand, to send downlink data ACK/NACK signals; and a transmission unit that sends the ACK/NACK signals using the dynamic ACK/NACK resource or the specified resource, as determined.

    Abstract: When downlink data allocation is indicated in an ePDCCH, this terminal device can determine PUCCH resources to be used in notification of response signals indicating results of error detection of downlink data without imposing scheduling restrictions on future DL subframes. In this device, an extraction unit (204) receives downlink data on multiple unit bands. A CRC unit (211) detects errors in the downlink data. A response signal generation unit (212) generates a response signal by using the results of error detection of the downlink data obtained by the CRC unit (211). The control unit (208) arranges the response signal in the PUCCH resources corresponding to the current DL subframe.

    Abstract: A terminal device is equipped with: a sequence determination unit that determines a sequence number with a different pattern than the assignment pattern for the sequence number assigned to the cell in which the host device resides; a reference signal generation unit that generates a reference signal for a sequence group corresponding to the sequence number that has been determined; and a wireless transmission unit that transmits the reference signal that has been generated to a base station. The sequence determination unit employs a configuration whereby, with the sequence number assigned to the cell in which the host device resides as a cell-specific sequence number, a dynamic offset which periodically changes over time and for which the same value is not consecutive is added to the cell-specific sequence number, thereby determining a sequence number which never overlaps with the cell-specific sequence number.

    Abstract: Provided is a terminal with which it is possible, in a heterogeneous cell network, to transmit a Periodic-Sounding Reference Signal (P-SRS) at a transmission bandwidth and power density necessary for carrying out both a process of selection of a transceiving participating base station and a process of frequency scheduling of a Packet Uplink Shared Channel (PUSCH). A terminal (300) comprises a receiving unit (301) which receives control information which includes information which denotes a P-SRS transmission parameter, and a transmission unit (303) which, using a transmission parameter which is included in the received control information, transmits a first P-SRS provided with a first bandwidth and a first power density at a first period, and transmits a second P-SRS provided with a second bandwidth which is narrower than the first bandwidth and second power density which is higher than the first power density at a second period.

    Abstract: Provided is a terminal apparatus in which, a transmission control unit (204) controls the transmission power of a sounding reference signal (SRS) by use of an offset value relative to the transmission power of a data signal, and a transmission unit (206) transmits the SRS by use of the transmission power as controlled. If a subframe to be used for transmitting the SRS is a predetermined subframe, the transmission control unit (204) uses a first offset value to control the transmission power of the SRS. Otherwise, the transmission control unit (204) uses a second offset value to control the transmission power of the SRS, The second offset value is an offset value that has been established so as to be transmitted to the serving cell of the terminal (200), and the first offset value is greater than the second offset value.
