Patent ID: 11902928
Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 10:
11. An apparatus for reporting a Reference Signal Timing Difference (RSTD) value in a wireless communication system, the apparatus comprising:
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 random access preamble related to a Synchronization Signal/Physical Broadcast Channel Block (SS/PBCH) block received from a specific cell included in a plurality of cells;
establishing an RRC connection to the specific cell by requesting a Radio Resource Control (RRC) connection based on a Random Access Response (RAR) received from the specific cell;
receiving, from a location server, a cell group identifier for a cell group including the plurality of cells and cell-independent information for each of the plurality of cells;
generating a first Positioning Reference Signal (PRS) sequence based on the cell group identifier;
detecting second PRS sequences transmitted from the plurality of cells,
wherein the first PRS sequence and the second PRS sequences are based on a same sequence with different cyclic shift values; and
reporting, to the location server, Reference Signal Timing Difference (RSTD) information based on the first PRS sequence, the second PRS sequences and the cell-independent information.
