A frame format is generated which can constrain the PAPR at a lower level without limitation in code selections in a radio communication system. In the radio communication system, each radio channel (a,b,c,d) is constituted by a control channel (DPCCH) and a data channel (DPDCH) and a plurality of the radio channels are divided in a frequency direction for mapping to a radio frame format (USER 1,...,USER 4). A control signal position on the control channel (DPCCH) is controlled in the radio frame format (USER 1,...,USER 4) for each user or service to reduce peak transmission power or a peak-to-average power ratio, PAPR, of a radio communication apparatus. |
