摘要： Provided is a wireless communication device. A PHICH reception unit (206) determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit (206) does not receive a PHICH in a subframe in which a terminal (200) monitors an E-PDCCH. A control signal reception unit (207) outputs a retransmission prompting signal to a signal allocation unit (210) when the signal outputted from the PHICH reception unit (206) is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit (207) outputs the detected UL grant to the signal allocation unit (210). The signal allocation unit (210) 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 (211).

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.

摘要： The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit (103) sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit (108) places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit (103) causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.

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： A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.

摘要： Provided is a wireless communication device. A PHICH reception unit (206) determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit (206) does not receive a PHICH in a subframe in which a terminal (200) monitors an E-PDCCH. A control signal reception unit (207) outputs a retransmission prompting signal to a signal allocation unit (210) when the signal outputted from the PHICH reception unit (206) is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit (207) outputs the detected UL grant to the signal allocation unit (210). The signal allocation unit (210) 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 (211).
