MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202544032413 A) filed by Nokia Solutions And Networks Oy on April 01, 2025, for Beam Nulling Method For Cross-Sector Interference Suppression.
Inventors include Andrei Malkov; Ulf Peter Falk; and Risto Pekka Valkonen.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: ABSTRACT BEAM NULLING METHOD FOR CROSS-SECTOR INTERFERENCE SUPPRESSION An apparatus (300), includes multiple sector antennas, each sector antenna of the sector 5 antennas includes a reception array of antenna array elements (215) and a transmission array of antenna array elements (205), and wherein each sector antenna is configured for transmitting signals to devices (712, 722, 732) within a sector and for receiving signals, using the reception array, from devices within the sector; and processing circuitry configured to transform a downlink beamforming matrix into a transformed downlink beamforming matrix using a closed- form 10 expression, wherein the transformed downlink beamforming matrix is configured to suppress both self-interference and cross- sector interference at individual receiver antenna array elements in a multi-sector antenna arrangement, generate beamformed data symbols based on the transformed downlink beamforming matrix, and deliver the beamformed data symbols associated with the current sector to a downlink transmit antenna included in the multi-sector antenna arrangement
