摘要： A wireless communication apparatus capable of minimizing the degradation of the separation characteristic of response signals to be code-multiplexed. In the apparatus, a control part (209) controls both a ZC sequence to be used for the primary spread in a spreading part (214) and a Walsh sequence to be used for the secondary spread in a spreading part (217) according to the associations between sequences and CCEs established in accordance with the probability of using response signal physical-resources corresponding to CCE numbers. The spreading part (214) performs the primary spread of the response signal by use of the ZC sequence established by the control part (209). The spreading part (217) performs the secondary spread of the response signal, to which CP has been added, by use of the Walsh sequence established by the control part (209).

摘要： A wireless communication apparatus capable of minimizing the degradation in separation characteristic of a code multiplexed response signal. In this apparatus, a control part (209) controls both a ZC sequence to be used in a primary spreading in a spreading part (214) and a Walsh sequence to be used in a secondary spreading in a spreading part (217) so as to allow a very small circular shift interval of the ZC sequence to absorb the interference components remaining in the response signal; the spreading part (214) uses the ZC sequence set by the control part (209) to primary spread the response signal; and the spreading part (217) uses the Walsh sequence set by the control part (209) to secondary spread the response signal to which CP has been added.

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.

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： Disclosed are a wireless base station, wireless terminal, and channel signal formation method that can prevent the quality of downstream assignment control data from degrading, while preventing the number of blind determinations from increasing on the wireless terminal on the receiving side of the downstream control channel signal. In a base station (100), a control unit (101) and a data size regulation unit (103) control the data size of downstream assignment control data and upstream assignment control data contained in the PDCCH signal based on the communication format used between the base station (100) and a terminal (200), the number of antennas (M) (nonnegative number) on the base station (100), the number of antennas (N) (nonnegative number) on the terminal (200), the bandwidth of the downstream band, and the bandwidth of the upstream band. Specifically, the control unit (101) determines it is unnecessary to adjust the aforementioned data size when the selected communication format is first established between multiple antennas and when where there are multiple for one of M and N and only one for the other.

摘要： Provided are a radio transmitting apparatus and a control signal transmitting method whereby the number of blind decodings on a control signal receiving side can be reduced without increasing the control signal allocation block rate. In a base station (100), a search space establishing unit (103) establishes two subsets into which a UE-SS established in a second transmission mode different from a first transmission mode has been divided and the number of which is the same as the number of the sub-modes of the first transmission mode, and an allocating unit (106) allocates the mutually different subsets to those two respective sub-modes. Each subset has a plurality of downstream control information allocation area candidates. In this way, the blind decoding area candidates related to DCI format corresponding to each sub-mode can be limited to the subset corresponding to each sub-mode.

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.
