Classification: CPC H | IPC H

Claim 3:
4. A user equipment (UE) in a wireless communication system, the UE comprising:
a memory;
a transceiver; and
at least one processor, operably coupled to the memory and the transceiver, configured to perform operations comprising:
performing a cell search for time and/or frequency synchronization with a cell, which comprises:
i) receiving, from a cell, a synchronization signal (SS) block;
ii) identifying an offset between the SS block and a remaining minimum system information (RMSI) control resource set (CORESET) from the SS block; and
iii) identifying the RMSI CORESET based on the offset;
monitoring the identified RMSI CORESET;
receiving, from the cell, an RMSI based on monitoring the RMSI CORESET;
receiving, from the cell, information on a length of a reference signal (RS) sequence and information on an offset of the RS sequence,
performing an RS sequence mapping to map the RS sequence to a physical resource block 0 (PRB0) of the UE within a bandwidth part (BWP) based on the length of the RS sequence and the offset of the RS sequence, and
transmitting, to the cell, the RS sequence,
wherein the length of the RS sequence and the offset of the RS sequence are used for the RS sequence mapping based on
the PRB0 of the UE being different from that of another UE within the BWP so that a common PRB indexing is unused for the RS sequence mapping.
