Zusammenfassung:Precoding matrix indicator (PMI) feedback for Type II channel state information (CSI) feedback in new radio (NR) multiple input, multiple output (MIMO) operations is discussed. According to various aspects, a user equipment (UE) determines a plurality of CSI feedback components and identifies a set of discarded ones of these components based on a particular component value of a precoding matrix indicator (PMI) component. The UE may then generate an adjusted CSI report by adjusting how the discarded feedback components are treated. The resulting adjusted CSI report may then be transmitted to a serving base station.
