Abstract: A response signal in each subframe is multiplied by a corresponding one of components forming one of a plurality of first sequences orthogonal to each other. The response signal is also multiplied by a second sequence defined by one of a plurality of cyclic shift indexes and one of a plurality of third sequences orthogonal to each other. Among a plurality of resources, a resource associated with one of at least two first sequences of the plurality of first sequences is different from a resource associated with another one of the at least two first sequences. Each of the plurality of resources is constituted by one of the plurality of cyclic shift indexes and one of the plurality of third sequences.

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 radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAP sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.

Abstract: A wireless communication base station apparatus that allows the number of times of blind decodings at a mobile station to be reduced without increasing the overhead caused by notifying information. In this apparatus, a CCE allocation part allocates allocation information allocated to a PDCCH received from modulation parts to a particular one of a plurality of search spaces that is corresponding to a CCE aggregation size of the PDCCH. A placement part then places the allocation information in one of downstream line resources, reserved for the PDCCH, that is corresponding to the CCE of the particular search space to which the allocation information has been allocated. A radio transmission part then transmits an OFDM symbol, in which the allocation information has been placed, to the mobile station from an antenna.

Abstract: Provided are a terminal device and a retransmission control method that make it possible to minimize increases in overhead in an uplink control channel (PUCCH), even if channel selection is used as the method to transmit response signals during carrier-aggregation communication using a plurality of downlink unit bands. On the basis of the generation status of uplink data and error-detection results obtained by a CRC unit, a control unit in the provided terminal uses response signal transmission rules to control the transmission of response signals or uplink control signals that indicate the generation of uplink data. If an uplink control signal and a response signal are generated simultaneously within the same transmission time unit, the control unit changes the resources allocated to the response signal and/or the phase point of the response signal in accordance with the number and position of ACKs within the error-detection result pattern.
