Abstract: If repetition transmission is applied to a response signal for a downlink data signal and an uplink signal, the uplink signal is repeatedly transmitted using a certain number of consecutive subframes starting with a first subframe, at which the repetition transmission of the uplink signal starts, and the response signal is repeatedly transmitted using at least the certain number of consecutive subframes starting with a second subframe, at which the repetition transmission of the response signal starts. The first subframe is set to be the same as the second subframe.

Abstract: Provided are a radio communication terminal apparatus and a radio transmission method by which intersymbol interference of DM-RS of a CoMP terminal and a Non-CoMP terminal can be reduced. A CoMP set setting unit (102) sets the cell IDs of all cells in the CoMP set in a cell selection unit (104), and a serving cell setting unit (103) sets the cell ID of the serving cell in the cell selection unit (104). The cell selection unit (104) selects the cell ID having a number closest to the cell ID of the serving cell from the cells in the CoMP set. A sequence information calculation unit (106) derives a sequence group number from the selected cell ID, and the sequence information calculation unit (106) calculates a sequence number from the derived sequence group number and a transmission bandwidth of the DM-RS.

Abstract: A wireless communication base station apparatus prevents degradation of throughput of LTE terminals, even when LTE terminals and LTE+terminals are present together. A setting section sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+terminals, based on the pattern of arrangement of reference signals employed solely by LTE+terminals. As to symbols that are mapped to antennas (110-1) to (110-4), an arrangement section arranges the characteristic cell reference signals employed by both LTE terminals and LTE+terminals in all of the resource blocks in a single frame. In contrast, as to symbols that are mapped to antennas (110-5) to (110-8), the arrangement section arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section, the characteristic cell reference signals that are employed solely by the LTE+terminals.

Abstract: A wireless communication base station device, terminal device, and method have reduced signaling while maintaining high scheduling gain. A judgment unit pre-stores a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality, and the maximum value for the number of clusters that is output by the judgment unit, a scheduling unit schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

Abstract: It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, w2} to be multiplied on the reference signal. A complex coefficient multiplication unit reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.

Abstract: Disclosed are a wireless communication base station device and a division number determination method that improve the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.

Abstract: A wireless communication base station device which makes it possible to provide a base station, terminal and CCE allocation method capable of reducing the number of times blind decoding of a terminal is performed, without increasing the CCE block rate, even when a plurality of unit bands are set in a terminal.

An allocation section (106) allocates control information solely to CCEs within the common search spaces set in specified unit bands among the plurality of unit bands, or solely to CCEs within individual search spaces set in specified unit bands.

Abstract: 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.

Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.
