Abstract  Abstract

A radio communication method in a radio communication system in which each of the user terminals together with the transmission of a data signal to a base station using different data transmission band frequencies that are assigned by the base station , performs a time division multiplexing of a pilot signal with the data signal and transmits the resulting signal to the base station; which comprises: a step of deciding a pilot transmission band for each user terminal such that the pilot transmission band covers the data transmission band of the user terminal by a frequency deviation; and a step of indicating to each user terminal to transmit the pilot signal I using the frequencies of said decided pilot transmission band, where a CAZAC sequence is used as said pilot signal, and where said instruction stage comprises: a stage of calculating an amount of said frequency deviation for each user terminal, and a cyclic offset amount of the CAZAC sequence that corresponds to the number of user determinals that are multiplexed by a cyclic offset and the amount of the frequency offset; and a step of indicating to each user terminal to perform a cyclic shift of said sequence of CAZAC that is used as the pilot signal in the amount of cyclic shift, and to perform a frequency deviation of the pilot transmission band in said amount of frequency deviation
