MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617062268 A) filed by Samsung Electronics Co. , Ltd. on May 16, 2026, for Electronic Device And Method For Transmitting And Receiving Signal In Multiple Input Multiple Output System.
Inventors include Kim, Kyeongyeon; Choi, Soongyoon; Kim, Minsung; Kim, Sangheon; and Yang, Hayoung.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: Provided is a radio unit (RU) device in embodiments. The device may comprise: a radio frequency (RF) transceiver; a fronthaul transceiver; a memory for storing instructions; and a processor. The instructions, when executed by the processor, cause the device to: acquire reference signals via the RF transceiver; acquire a transformed covariance matrix of the reference signals with respect to noise and interference through random embedding for dimensionality reduction; acquire an extraction matrix through the subspace decomposition of the transformed covariance matrix; use the extraction matrix to pre-combine uplink signals acquired via the RF transceiver; and transmit data of the pre-combined uplink signals to a digital unit (DU) via the fronthaul transceiver. The random embedding may be used to transform a first dimension of the number of reception layers of the RU into a second dimension of a number smaller than the number of reception layers.
