Abstract:
1. A mobile station device to communicate with a base station device over a plurality of subframes on a plurality of cells, the mobile station device comprising: a receiving unit configured to receive data transmitted over a plurality of downlink subframes from the base station device; a ACK/NACK generating unit configured to generate ACK/NACK for reception of the data; a resource selecting unit configured to select one PUCCH resource from a plurality of PUCCH resources in an uplink subframe, in accordance with information of the ACK/NACK, by PUCCH format 1b with channel selection; a parameter setting unit configured to set at least one parameter value to prescribe transmit power of a PUCCH transmitted using the selected PUCCH resource; and a transmitting unit configured to transmit, with the prescribed transmit power, modulation signals related to the ACK/NACK, the modulation signals are mapped to the selected PUCCH resource for the PUCCH, wherein the parameter setting unit is configured to determine the parameter value in accordance with the number of cells having received the data over the plurality of downlink subframes, the parameter value which is determined in the case of having received the data on a cell is different from the parameter value which is determined in the case of having received the data on a plurality of cells.
