Abstract:
A method of a user equipment (UE) for controlling reference signal in a wireless communication system is provided. The method comprises receiving, from a base station (BS), a demodulation reference signal (DMRS) of a physical broadcasting channel (PBCH) over a downlink channel and determining resources to be used for the DMRS of the PBCH. A pseudo-noise (PN) sequence that is mapped to the resources to be used for the DMRS of the PBCH is generated by a base station (BS). The PN sequence is generated based on an initial condition including a physical cell identification (ID) and timing information comprising at least one of an index of synchronization signal block (SSB) or an index of a half frame within a frame based on a carrier frequency range. The index of SSB comprises at least one of a partial or whole index of SSB.
