Abstract  Abstract

A radio communication system where a terminal transmits a data signal to a base station using data transmission band frequencies assigned by the base station, and performs time-division multiplexing of a pilot signal with the data signal and transmits the resulting signal to the base station. Including deciding a pilot transmission band for the user terminal covering the data transmission band of the user terminal by frequency offset; and instructing the user terminal to transmit the pilot signal using the decided pilot transmission band. A CAZAC sequence is used as the pilot signal. The instructing includes calculating a frequency offset amount for the user terminal, and a cyclic shift amount of the CAZAC sequence and the frequency offset amount; instructing the user terminal to perform cyclic shift of the CAZAC sequence by the cyclic shift amount, and perform frequency offset of the pilot transmission band by the frequency offset amount.
