Claim 0:
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a synchronization signal/physical broadcast channel (SS/PBCH) block comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH);
receiving system information based on the SS/PBCH block;
after the reception of the system information:
receiving information related to a positioning reference signal (PRS) sequence identifier (ID);
receiving a PRS related to the PRS sequence ID;
performing measurements based on the PRS; and
reporting a result of the measurements,
wherein a pseudo-random sequence generator related to sequence generation of the PRS is initialized according to the following equation:, c
