MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202617069412 A) filed by Samsung Electronics Co. , Ltd. on June 03, 2026, for Electronic Device And Method For Determining Precoder In Wireless Communication System.
Inventor includes Lee, Dongjae.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: In embodiments, a device of a digital unit (DU) is provided. The device may comprise: a transceiver; a memory for storing instructions; and a processor. The instructions, when executed by the processor, may instruct the device to: obtain a channel frequency response through reference signals from a terminal; obtain eigenvectors through eigen decomposition for the channel frequency response; obtain transform vectors by performing a two-dimensional Fourier transform on the eigenvectors; identify basis vectors among a plurality of basis vectors for an enhanced Type 2 codebook through a decision metric according to the transform vectors; determine a precoding matrix using the identified basis vectors; and transmit downlink data to which the precoding matrix is applied to the terminal through a radio unit (RU).
