The present invention relates to a method for determining the propagation delay of a signal. In the method a burst signal transmitted from one or more access points is received, said signal comprising at least one part containing fixed information. Samples are taken from the received signal to produce a sampled signal (s(n)). The received signal comprises signal components propagated via one or several paths. In the method the sampled signal (s(n)) and the signal corresponding to said fixed information (t(n)) are correlated with each other, wherein the correlation results produced in the correlation are processed by separating at least one signal component from the correlation results. Said signal corresponding to said fixed information (t(n)) is used in the separation. As a result of the processing, values corresponding to the maximum correlation are searched for, wherein a temporally first value is determined from the found values corresponding to the maximum correlation, said first value being used for determining the timing of the signal
