MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617055726 A) filed by Samsung Electronics Co. , Ltd. on May 01, 2026, for Method For Transmitting Channel State Information Reference Signal.
Inventors include Alexei, Davydov; Esiunin, Denis; Dmitry, Dikarev; Gregory, Ermolaev; Gregory, Morozov; and Vladimir, Pestretsov.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: The disclosure relates to a method for transmitting channel state information reference signal (CSI-RS). The method includes setting, at a base station, CSI-RS transmission configuration information, including one or more code-division multiplexing (CDM) groups with uniform frequency distribution of resource elements (RE) in each CDM group, transmitting the CSI-RS transmission configuration information from the base station (BS) to user equipment (UE), generating, for each antenna port of the base station, a CSI-RS modulated by orthogonal cover code (OCC) in frequency domain (FD) across resource elements according to discrete Fourier transform (DFT) vector and in time domain (TD) across one or more Orthogonal Frequency-Division Multiplexing (OFDM) symbols according to Walsh-Hadamard (WH) code, and transmitting the CSI-RS from the BS to the UE according to the CSI-RS transmission configuration.
