Abstract: This base station selects one of multiple mutually orthogonal code sequences which is multiplied by an uplink signal containing a demodulation reference signal repeated over multiple subframes, and sends information indicating the code sequence by using a field for notifying the terminal configured to transmit the repeated uplink signal of the orthogonal sequence and a cyclic shift used in the demodulation reference signal. The terminal uses the field for notification of the orthogonal sequence and the cyclic shift used in the demodulation reference signal to receive the information indicating one of the multiple mutually orthogonal code sequences, and multiplies the one code signal indicated by the aforementioned information by the uplink signal containing the demodulation reference signal repeated across the multiple subframes.

Abstract: DISCLOSED ARE A WIRELESS COMMUNICATION APPARATUS AND FREQUENCY HOPPING METHOD WHICH MINIMIZE THE CHANGE IN THE INSTANTANEOUS POWER DISTRIBUTION CHARACTERISTICS OF THE TIME WAVEFORM OF TRANSMISSION SIGNALS WHEN A PLURALITY OF CHANNELS ARE MULTIPLEXED BY FREQUENCY DIVISION. AT A TERMINAL (200, 200A), A MAPPING UNIT (212) MAPS THE PUCCH TO FREQUENCY RESOURCES OF A FIRST SLOT, MAPS THE PUSCH TO FREQUENCY RESOURCES, AMONG THE FREQUENCY RESOURCES OF THE FIRST SLOT, SEPARATED EXACTLY BY PREDETERMINED FREQUENCY SPACING (B) FROM THE FREQUENCY RESOURCES TO WHICH THE PUCCH IS MAPPED, AND CYCLICALLY SHIFTS THE FREQUENCIES SO AS TO MAP THE PUCCH AND PUSCH TO FREQUENCY RESOURCES, WITHIN AN IDFT OR IFFT BANDWIDTH, OF A SECOND SLOT WHILE MAINTAINING THE PREDETERMINED FREQUENCY SPACING (B), THEREBY ALLOWING FREQUENCY HOPPING OF THE PUCCH AND PUSCH BETWEEN THE FIRST SLOT AND THE SECOND SLOT.

Abstract: Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band and the terminal device is capable of providing a retransmission control method. In this device at the time of channel selection a control unit (208) selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station (100) and PUCCH resources mapped to a CCE and controls the transmission of the response signal. A response signal generating unit (212) supports implicit signaling with respect to any given response signal and at the same time as supporting LTE fallback from 2CC uses a mapping method that between bits smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

Abstract: A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

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 ZAC 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 in order to randomize the intra-cell interference.

Abstract: A PUCCH resource collision between a normal mode terminal and MTC coverage enhancement mode terminal is avoided. A terminal includes a receiving section that receives control information indicating assignment of downlink data, and the downlink data; and a transmitting section that transmits a response signal using a resource in a first resource group when the terminal is a first terminal to which repetition transmission is applied, and that transmits the response signal using a resource in a second resource group that is different from the first resource group, when the terminal is a second terminal to which the repetition transmission is not applied.
