1. An apparatus of a user equipment (UE) comprising a baseband processor configured to:
generate a demodulation reference signal (DMRS) sequence from a Gold code based on an initialization value, wherein the initialization value is determined based on
a cell identification (ID) parameter, upon which
a modulus operation is performed by the baseband processor; and
separately, a mathematical floor operation is performed by the baseband processor; and
at least a portion of a synchronization signal (SS) block index;
receive a physical broadcast channel (PBCH) DMRS; and
process the PBCH DMRS based on the DMRS sequence.
