A frame format is generated which can constrain the PAPR at a lower level without limitation in code selections in a radio communication system. The radio communication system with each radio channel constituted by a control channel and a data channel divides a plurality of the radio channels in a frequency direction for mapping to a radio frame format. A control signal position on the control channel is controlled in the radio frame format for each user or service to reduce peak transmission power or a peak-to-average power ratio of a radio communication apparatus.
