Abstract: A synchronization method of a user equipment (UE) and a base station (BS) in a wireless communication system, a UE and a BS for establishing synchronization in a wireless communication system, and a non-transitory computer-readable recording medium are provided. The synchronization method of a UE includes detecting a first synchronization signal from a signal received from a BS, detecting repeatedly receivable one or more synchronization signals after the first synchronization signal is detected, based on each of blocks corresponding to a preset synchronization signal mapping pattern on time-frequency resources, combining the one or more synchronization signals, and establishing synchronization with the BS based on a block corresponding to a highest strength of the combined one or more synchronization signals, among the blocks.
