  • Codebook subset restriction for CSI
    Patent number: 10924163
    Abstract: Network devices and systems in 5G advance long term evolution (LTE) and new radio (NR) infrastructures utilize beam management operations to ensure communications for channel state information (CSI) reporting by a user equipment (UE). CSI report configuration reporting settings are processed based on a codebook subset restriction to indicate pre-coding matrix indicators (PMIs) that are restricted and non-restricted for PMI reporting associated with a rank indicator (RI). Based on the codebook subset restriction, an advanced CSI codebook or a new radio (NR) codebook is generated to be transmitted on non-restricted beams of the codebook subset restriction.
