Abstract
A computer implemented method for providing OTDOA timing information comprising defining an FFT window pair for estimating a value of reference signal time difference 'RSTD' for at least one base station and a reference cell, receiving a PRS from the at least one base station and the reference cell, executing an FFT per OFDM symbol of the PRS for each FFT window of the FFT window pair, obtaining a first FFT output vector per OFDM symbol of each FFT window, for each first output vector, descrambling tones corresponding to the known position of the PRS, wherein all other tones are set to zero, combining vectors based on respective first FFT output vectors, executing an iFFT to convert to the time domain; and calculating an estimated value of reference signal time difference 'RSTD' for the at least one base station and the reference cell.
