Abstract: A threshold condition formed relative to the strongest peak (e.g., in a signaled DL-PRS-specific search window) is used in the search for the first peak to be used for Time of Arrival (TOA) estimation. Such a threshold condition may be used with DL-PRSs that are homogenous or inhomogeneous, and in each of these combined (or not) with cyclic shifts. In so doing, the solutions 0 (100, 200, 300, 400) presented herein avoid detecting false peaks.
