Claim 6:
7. An apparatus configured to operate in a wireless communication system, the apparatus comprising:
a transceiver; and
at least one processor coupled with the transceiver,
wherein the at least one processor is configured to:
receive 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);
receive system information based on the SS/PBCH block;
after the reception of the system information:
receive information related to a positioning reference signal (PRS) sequence identifier (ID); and
receive a PRS related to the PRS sequence ID, and
wherein a pseudo-random sequence generator related to sequence generation of the PRS is initialized according to the following equation:, c
