Included are: a spread code channel selection step (S109) of randomly selecting a spread code channel to be used for CDMA spreading transport data; a time slot channel selection step (S110) of randomly selecting a time slot channel on which to transmit the CDMA spread transport data; a frequency channel selection step (S111) of randomly selecting a frequency channel on which to transmit the CDMA spread transport data; and a transmission step (S114) of transmitting the CDMA spread transport data by use of the time slot channel selected in the time slot channel selection step (S110), the frequency corresponding to the frequency channel selected in the frequency channel selection step (S111), and the spread code channel selected in the spread code channel selection step (S109).
