摘要： A radio transmission apparatus and a radio transmission method suppress lowering of the throughput caused by switching between the single carrier communication method and the multi-carrier communication method while suppressing increase in the signaling amount. A PHR threshold value setter sets a threshold value at a position greater by a predetermined value than the PHR at which the throughput performance of the SC-FDMA coincides with that of the OFDMA. A trigger signal transmission judger judges that a mobile station transmits a trigger signal for switching from the OFDMA to the SC-FDMA if the PHR in the OFDMA communication method is lower than the threshold value.

A base station (200) can communicate by using a plurality of downlink unit bands and a smaller number of uplink unit bands. A control unit (201) allocates uplink resource allocation information and downlink resource allocation information to a PDCCH which is arranged in each of the plurality of downlink unit bands, and allocates a response signal to the uplink line data to a PHICH which is arranged in the same number of downlink unit bands from the plurality of downlink unit bands as there are uplink unit bands. A transmit RF unit (212) transmits the resource allocation information or the response signal.

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 wireless transmission device, a wireless reception device, and a bandwidth allocation method for, when non-contiguous bands allocation is performed, improving the frequency resource use efficiency of a system and thereby improving the system performance. RIV decoding unit (106) decodes start RBG# and end RBG# that are indicated by each RIV output from scheduling information decoding unit (104).

摘要： Provided are a wireless communication terminal apparatus, a radio communication base station apparatus and a wireless communication method whereby the increase in the number of signaling bits can be suppressed, while the SRS capacity can be improved. RS type determining unit (105) determines, based on scheduling information, that the signal is an SRS signal accompanied by no data or a DMRS signal accompanied by data. CS amount deciding unit (106) holds a CS amount for DMRS and a CS amount for SRS that are defined such that the CS amount for SRS includes a CS amount not included in the CS amount for DMRS. The CS amount deciding unit (106) uses CS amount notification information, which is included in the scheduling information, and the CS amount definition to derive a CS amount in accordance with the RS type outputted from the RS type determining unit (105).

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.
