MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202617070346 A) filed by Samsung Electronics Co. , Ltd. on June 05, 2026, for Electronic Device And Method For Identifying Frequency Offset Of Random Access Signal In Wireless Communication System.
Inventors include Kim, Hyuncheol; and Lee, Jonghyeuk.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: According to an embodiment, a method performed by an electronic device may comprise an operation of acquiring, on the basis of a physical random access channel (PRACH) region, a preamble signal related to signals received via a plurality of antennas. The method may comprise an operation of acquiring delay information for the preamble signal. The method may comprise an operation of acquiring energy information, acquired through a correlation operation, about the preamble signal. The method may comprise an operation of estimating a frequency offset for the preamble signal on the basis of the delay information and the energy information. The method may comprise an operation of compensating for the estimated frequency offset for a received data signal on the basis of a physical uplink shared channel (PUSCH) region.
