    摘要: Provided are a terminal device and a retransmission control method by which, when carrier aggregation communication using a plurality of downlink unit bands is applied, the quality of downlink data transmitted by each downlink unit band can be maintained, while suppressing the increase in overhead of downlink allocation control information. In a terminal (200), a control unit (208) performs transmission control of a response signal on the basis of a reception success/failure pattern of downlink data received by a downlink unit band which is included in a unit band group set in the terminal itself. The control unit (208) makes the phase points of the response signal different in accordance with a number of downlink data which has been successively received, namely, a number of ACK, in the reception success/failure pattern, and makes the phase points of the response signal between reception success/failure patterns identical when there are a plurality of reception success/failure patterns having the same ACK number.

    摘要: Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.

    摘要: A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit (103) sets a search space having a plurality of allocation candidates, in both regions. An allocation unit (106) allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.
