MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202441077293 A) filed by Centre Of Excellence In Wireless Technology; and Indian Institute Of Technology Madras Iit Madras on October 11, 2024, for Methods And Systems For Selection And Reporting Of Near-Field Precoders.
Inventors include Pardhasarathy Jyothi; Jutke Goutham; Dhivagar Baskaran; Jeniston Deviraj Klutto Milleth; and Bhaskar Ramamurthi.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present application discloses a method of using a precoder matrix for wireless signal transmission in an OFDM based communication systems in accordance with an embodiment of the present disclosure. The method comprises: signaling by a Base station (BS), a configuration for receiving a set of reference signals by a UE for estimating the wireless channel between the BS and the UE, signaling by the BS, a configuration of at least one of a set of first basis vectors, a set of second basis vectors, a set of third basis vectors and a set of fourth basis vectors to the UE explicitly or implicitly, receiving by the BS, at least one of a subset of the first basis vectors, a subset of the second basis vectors, a first subset of the third basis vectors and a first subset of the fourth basis vectors, determining by the BS, a set of second subset of third basis vectors based on the first subset of third basis vectors and a set of second subset of fourth basis vectors based on the first subset of fourth basis vectors, determining by the BS, a precoder matrix based on the subset of first basis vectors, the subset of second basis vectors, the subset of third basis vectors and the subset of fourth basis vectors, obtaining by the BS, a precoded wireless signal by precoding a wireless signal using the precoder matrix and transmitting by the BS, the precoded wireless signal.
