Abstract: A method and apparatus are provided. The method includes receiving reference signal resource elements from a transceiver, determining a channel impulse response (CIR) signal based on the received reference signal resource elements, estimating a coarse value of a FAP of the reference signal resource elements based on the CIR signal, estimating a fine value of the FAP of the reference signal resource elements based on CIR samples around the FAP location, and combining the coarse value estimate and the fine value estimate to determine the FAP estimate.
