Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 13:
14. A base station (BS) configured to receive a Reference Signal Timing Difference (RSTD) value in a wireless communication system, the BS comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
transmitting a Synchronization Signal/Physical Broadcast Channel Block (SS/PBCH) block transmitted on a cell;
receiving a random access preamble related to the SS/PBCH block;
transmitting, via the at least one transceiver, 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, via the at least one transceiver 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.
