Abstract: Embodiments herein provide a method of performing a cell search by user equipment (UE). The method includes receiving a signal from the base station. The method includes estimating a fractional frequency offset (FFO) along with a coarse timing using a cyclic prefix (CP) in the received signal. The method includes compensating the received signal with the estimated FFO. Further, the method includes applying a correlation on the compensated received signal with each of a plurality of primary synchronization signals (PSSs) generated by the UE. Furthermore, the method includes determining a plurality of cell search parameters based on the applied correlation.
