Summary:A synchronization signal format for a cell search method is proposed to reduce cell search complexity and cell search time. A synchronization signal is embedded with a unique sequence that is consecutively repeated multiple times in time domain. Different unique sequences represent different control information to be broadcasted from a base station to user equipments via synchronization signal transmissions. A two-stage cell search method is then applied in accordance with the synchronization signal format. In a first acquisition stage, a coarse location of the synchronization signal is acquired. In a second fine searching stage, the unique sequence is detected within a searching range of the coarse location.
