Classification: CPC H  G | IPC G  H

Claim 12:
13. A method of receiving a Reference Signal Timing Difference (RSTD) value by a base station (BS) in a wireless communication system, the method comprising:
transmitting a Synchronization Signal/Physical Broadcast Channel Block (SS/PBCH) block on a cell;
receiving a random access preamble related to the SS/PBCH block;
transmitting a Random Access Response (RAR) in response to the random access preamble;
performing a Radio Resource Control (RRC) connection to a user equipment (UE) based on the RAR;
generating a second PRS sequence for the cell based on a cell group identifier for a cell group including the cell;
transmitting, to the UE, the second PRS sequence on the cell; and
receiving, from the UE, the RSTD information,
wherein the RSTD information is based on a first PRS sequence, the second PRS sequence and the cell-independent information, and
wherein the first PRS sequence and the second PRS sequences are based on a same sequence with different cyclic shift values.
