Title: METHOD AND APPARATUS FOR COMMUNICATING REFERENCE SIGNAL FOR BROADCAST CHANNEL
Abstract:
Provided is a method and apparatus for transmitting a reference signal. The method may comprise: determining, based on at least one of a synchronization signal (SS) block index or a half-frame timing index, an initialization value for a reference signal associated with a physical broadcast channel (PBCH); generating, based on the initialization value, the reference signal associated with a PBCH; mapping, based on one or more of a frequency domain shift value or a time domain shift value, the generated reference signal to resource elements (REs); and transmitting, to a terminal, the mapped reference signal and the PBCH.
