Abstract

A computer implemented method of providing RSTD data comprising receiving an uncertainty window centered around an expected RSTD value, determining the PDP of each reference OFDM symbol within the uncertainty window, obtaining a main PDP by calculating a parameter indicative of signal quality for each determined PDP, the main PDP having the highest signal quality, obtaining a preceding PDP of the Main PDP, obtaining a succeeding PDP of the Main PDP, determining PDP metrics comprising, determining a channel metric for each of the main, preceding and succeeding PDPs, determining a channel main tap for each of the main, preceding and succeeding PDPs, determining a delay estimate for each of the main, preceding and succeeding PDPs, wherein if the main PDP is a combined PDP, performing coherence testing on the PDP metrics to detect any ambiguity in the delay estimate of the main PDP, and correcting any ambiguity.
