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.
