摘要

The following steps are included: a spreading code channel selection step (S109) for selecting randomly a spreading code channel for CDMA spreading of transmission data, a time slot channel selection step (S10) for selecting randomly a time slot channel for transmitting the CDMA-spread transmission data, a frequency channel selection step (S111) for selecting randomly a frequency channel for transmitting the CMDA-spread transmission data, and a transmission step (S 114) for transmitting the transmission data CDMA-spread in the spreading code channel selected in the spreading code channel selection step (S109), using the time slot channel selected in the time slot channel selection step (S110), at a frequency corresponding to the frequency channel selected in the frequency channel selection step (S111).
