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.

Embodiments herein disclose a method and a base station for accessing a channel of an unlicensed band in a wireless communication network. The method includes maintaining a plurality of virtual stations by the base station in the wireless communication network based on a value. Further, the method includes contending to access the channel using the plurality of virtual stations. Each virtual station in the plurality of virtual stations includes a contention window and a counter value.
