A method for measuring characteristics of a propagated radio-wave on the basis of a reference signal, wherein the reference signal is obtained by receiving and demodulating the propagated radio-wave, comprising the steps of: estimating characteristics of a propagation-path, through which the radio-wave has been transmitted, on the basis of the reference signal; determining a desired-signal power and an interference-signal power of the propagated radio-wave on the basis of the estimated characteristics: and deriving an SIR by performing calculations on the desired-signal power and the interference-signal power.
