MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517059028 A) filed by Interdigital Patent Holdings, Inc., Wilmington, U.S.A., on June 19, for 'enhanced system information block acquisition in cell-free mimo deployments.'
Inventor(s) include Svedman, Patrick; Tsai, Allan; Pan, Kyle Jung-Lin; Lorca Hernando, Javier; Shojaeifard, Arman; and Zhang, Guodong.
The application for the patent was published on July 4, under issue no. 27/2025.
According to the abstract released by the Intellectual Property India: "Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for enhanced system information block, SIB, acquisition in cell-free Multiple Input Multiple Output, MIMO, deployments are described. System information, SI, overhead in cell-free MIMO deployment based on legacy Synchronization Signal Blocks, SSBs, is addressed. Overhead caused by transmission of SI messages in these deployments may be reduced. Enhanced SIB1 message is proposed, in which a WTRU blindly detects the PCI used for SIB1 in a super cell, based on a PCI hypothesis set. A WTRU determines a PCI hypothesis set, e.g., based on previously received SI, the frequency band, the PCI of the detected SSB, etc. The WTRU blindly receives/decodes SIB1 PDCCH, using the PCI hypotheses. The WTRU receives SIB1 PDSCH based on PCI hypothesis used for successfully received SIB1 PDCCH."
The patent application was internationally filed on Dec. 20, 2023, under International application No.PCT/US2023/085084.
