Moreover, the base station measures the reception quality of signals received from a user terminal, makes reference to the stored correlation and finds a pilot sequence having Peak to Average Power characteristic that correspond to said reception quality, then sends an instruction to the user terminal so that the user terminal transmits the pilot sequence using the frequencies assigned to this pilot sequence.
