    Abstract: Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.

    Abstract: A communication apparatus has a receiver and a decoder. The receiver receives a control signal including first downlink control information and second downlink control information, and receives decoding area information that indicates whether the extended Physical Downlink Control Channel (PDCCH) should be decoded for each of a plurality of terminal apparatuses. The decoder decodes each of a plurality of first mapping candidates in the PDCCH area or decodes each of the plurality of first mapping candidates in the PDCCH area and each of the plurality of second mapping candidates in the extended PDCCH. A number of the second mapping candidates included in the user-specific search space equals to or is more than a number of the first mapping candidates included in the common search space.

    Abstract: A base station apparatus is disclosed in which control section (150) generates an index indicating a response signal resource to be used for transmission of a response signal in response to downlink data of a plurality of CCs for at least each second CC, and transmitting section (160) transmits control information including the index. When a terminal receives the control information using only one second CC or two or more CCs among the plurality of CCs, the terminal apparatus determines the response signal resource based on the index of the second CC. Control section (150) specifies, as the response signal resource, using the index of the second CC, a first resource for transmission of a response signal in response to downlink data transmitted using only one CC or a second resource for transmission of a plurality of response signals in response to downlink data transmitted using a plurality of CCs.

    Abstract: Provided is a terminal device with which deterioration in hybrid automatic repeat request (HARQ) retransmission performance can be inhibited by continuing a downlink (DL) HARQ process for DL data before and after changing the uplink link-DL configuration. In this device, a decoder (210) stores, in a retransmission buffer, DL data transmitted from a base station, and decodes the DL data, and a wireless transmitter (222) transmits a response signal generated using a DL-data-error detection result. A soft buffer is partitioned into a plurality of regions for each retransmission process on the basis of the highest values among retransmission process numbers respectively stated in a plurality of configuration patterns which can be set in the terminal (200).
