Claim 12:
13. 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:
transmit 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);
transmit system information after the transmission of the SS/PBCH block;
after the transmission of the system information:
transmit information related to a positioning reference signal (PRS) sequence identifier (ID);
transmit a PRS related to the PRS sequence ID; and
receiving a result of measurements related to the PRS,
wherein a pseudo-random sequence generator related to sequence generation of the PRS is initialized according to the following equation:, c
