Claim 0:
1. A wireless user device comprising:
at least one antenna to receive at least one wireless signal from a base station;
at least one processor; and
memory storing instructions that, when executed by the at least one processor, cause the wireless user device to:
receive a synchronization signal (SS) block in a frame, wherein the SS block comprises:
a primary synchronization signal;
a secondary synchronization signal;
a physical broadcast channel (PBCH); and
a demodulation reference signal for the PBCH, wherein a frequency domain shift value is associated with at least one resource to which the demodulation reference signal is mapped, and wherein an initialization value for the demodulation reference signal is associated with:

a cell identifier;
an SS block index; and
an index associated with a time interval; and
demodulate, based on the demodulation reference signal, the PBCH.
