  • CSI FEEDBACK DESIGN FOR NEW RADIO
    Publication number: 20220070694
    Abstract: It is recognized herein that as the number of transmit antennas in cellular systems (e.g., NR or 5G systems) increase, the Channel State information (CSI) feedback overhead may increase to unacceptable levels, and the current CSI feedback might not support beamforming training for NR. Embodiments described herein provide an enhanced and more efficient design for Channel State Information feedback as compared to current approaches.
