    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 to randomize the intra-cell interference.

    Abstract: Provided are a base station, a terminal, a band allocation method, and a downlink data communication method with which bands can be efficiently allocated. In a base station in which a plurality of unit bands can be allocated to a single communication, when a data receiver acquires terminal capability information transmitted by a terminal in the initial access unit band and the bandwidth available for communication indicated by the terminal capability information can accommodate a plurality of unit bands, a unit band group which includes the initial access unit band as well as the unit bands adjacent thereto is allocated to the terminal, and a communication band movement indication, which indicates the movement of the center frequency in the communication band of the terminal toward the center frequency in the unit band group, is transmitted to the terminal using the initial access unit band.

    Abstract: To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing overhead of retransmission control signaling. Where a retransmission control method is employed with adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>⅔, two bits are set. In a case where the encoding rate ⅓
