Abstract: Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance 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 that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) 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: When downlink data allocation is indicated in an ePDCCH, this terminal device can determine PUCCH resources to be used in notification of response signals indicating results of error detection of downlink data without imposing scheduling restrictions on future DL subframes. In this device, an extraction unit (204) receives downlink data on multiple unit bands. A CRC unit (211) detects errors in the downlink data. A response signal generation unit (212) generates a response signal by using the results of error detection of the downlink data obtained by the CRC unit (211). The control unit (208) arranges the response signal in the PUCCH resources corresponding to the current DL subframe.

Abstract: This invention is a transmission device capable of enhancing the reception characteristics of a terminal when employing transmit diversity using two antenna ports in an ePDCCH. In a base station (100) that transmits a reference signal to a terminal (200) using two antenna ports, a setting unit (102), on the basis of the reception quality of the terminal, sets as the aforementioned two antenna ports either a first antenna port pair for which DMRS (reference signals) do not undergo mutual code multiplexing, or a second antenna port pair for which the DMRS do undergo code multiplexing. A transmitter (109) transmits the DMRS from the two antenna ports set in the setting unit (102).

Abstract: Provided is a terminal apparatus that can suppress the increase in interference between pilot signals in the same slot, while also suppressing the degradation of the flexibility to design cell cluster structures. When hopping information indicates an inter-slot hopping, a mapping unit (212) arranges a first pilot sequences in which a group to which the sequences used in respective slots belong varies on a slot-by-slot basis. When the hopping information indicates an inter-subframe hopping, the mapping unit (212) arranges a second pilot sequences in which a group to which the sequences used in respective slots belong varies on a subframe-by-subframe basis. The sequence group to which the sequences used in any one of the subframes in the second pilot sequences belong is identical with the sequence group to which the sequence used in any one of the slots included in that one subframe in the first pilot sequences belongs.

Abstract: A link adaptation method and others wherein feedback information amount can be reduced. According to this method, a receiving apparatus (100) calculates, based on a channel matrix, a capacity (C) and a stream ratio (r) that is a ratio of the reception qualities of streams, and then transmits, as feedback information, the calculated capacity (C) and stream ratio (r) to a transmitting apparatus. In the transmitting apparatus (200), the number of transmittable streams, the modulation scheme and the fed-back capacity (C) are used to calculate the encoding ratio (R) and sequence length (S)ofspatialmultiplexedsymbols. Then, the modulation scheme (M1-Mn) of each stream is decided based on the fed-back stream ratio (r) and the sequence length (S) of spatial multiplexed symbols.
