MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202647108162 A) filed by Telefonaktiebolaget Lm Ericsson Publ on September 09, 2026, for Tx Beam Nulling For Suppressing Sbfd Interference.
Inventors include Almquist, Gustav; Axns, Johan; Ambede, Abhishek; and Cheng, Jung-Fu.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: Various embodiments disclosed herein provide a method for suppressing SubBand Full Duplex (SBFD) interference using transmission beam nulling in a network node or a user equipment (UE). In an embodiment from a perspective of a network node, a transmit nulling precoder can be designed that is based on self-interference channel coefficients corresponding to an uplink (UL) subband, while a downlink (DL) transmission precoder can be designed that is based on DL subband channel coefficients. These precoders can then be applied to a signal before transmission to one or more UEs. From the perspective of a UE, the transmit nulling precoder can be designed based on self-interference channel coefficients corresponding to a DL subband, while the UL transmission precoder is based on UL subband channel coefficients.
