FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a mobile communication system. At a terminal (200), a mapping unit (212) maps a 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.
EFFECT: invention enables to minimise 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.
