Abstract

A method and apparatus may include configuring, by a base station, a synchronization signal. The synchronization signal may be aligned with a sub carrier spacing grid of a radio access technology. The synchronization signal may be positioned at a frequency location that is the same or about the same as a frequency step of a channel raster. The synchronization signal may be transmitted to a user equipment so that the center of the synchronization signal is transmitted with a frequency offset with respect to the center of the radio-access technology bandwidth.
