Abstract: Systems and methods for blind detection of a numerology of a received signal are described. In one aspect, a method is provided for a user equipment (UE) to blindly detect the numerology of a received signal. The method includes correlating cyclic prefix (CP) signals in the received signal in the time domain based on a plurality of hypotheses of subcarrier spacing (SCS) and determining a numerology of the received signal for a corresponding hypothesis of SCS of the plurality of hypotheses based on the correlated CP signals.
