| description | A method in a first wireless device (WD) is described. The method includes determining a plurality of expected response signals, each having a scrambling seed number and an expected sequence of time domain symbols; receiving a plurality of response signals; determining a plurality of frequency shifted time domain samples, cross-correlating each frequency shifted time domain sample with the expected sequence of time domain symbols, for each scrambling seed number of each expected response signal; determining a maximum correlation value for each frequency shift and each frequency shifted time domain sample; summing the maximum correlation value for each frequency shift, each frequency shifted time domain sample, and each response signal; determining a peak correlation value based on the summed maximum correlation value; and determining at least the round trip time associated with the plurality of ranging signals based at least in part on the peak correlation value. |
