In a pilot signal transmission method for raising the SIR measurement accuracy for transmission power control during high-speed transmission and thus reducing the block error rate and improving the throughput, a first SIR value measured by first pilot signals and second SIR value measured by second pilot signals are first compared, and the presence or absence of second pilot signals then determined in slot units based on the comparison results. When the second pilot signals exist, the second pilot signals are used in addition to the first pilot signals in the SIR measurement for high-speed closed-loop transmission power control. When the second pilot signals do not exist, only the first pilot signals are used in the SIR measurement for high-speed closed-loop transmission power control.
