Methods, systems, and devices are described for directional synchronization signal signals in a millimeter wave communication system. A user equipment (UE) may receive a narrowband signal component of a synchronization signal for the millimeter wave communications. The narrowband signal component may include correlation information. The UE may use the correlation information to identify a wideband signal component of the synchronization signal for the millimeter wave communications. The UE may search frequencies associated with a first frequency location determined from the correlation information to identify and detect the wideband signal component of the synchronization signal.
