Abstract
Apparatuses, methods, and systems are disclosed for preparing channel state information ('CSI'). One apparatus includes a processor and a transceiver configured to communicate with a base unit over a RAN using spatial multiplexing, wherein multiple transmission layers are transmitted at a time, each transmission layer comprising multiple beams. The processor identifies a set of non-zero amplitude parameters and a set of zero amplitude parameters over the set of layers. The processor computes a number of non-zero amplitude parameters and determines an indication of the number of non-zero amplitude parameters. The processor determines the location of zero amplitude parameters to generate a set of location bits. The processor prepares CSI that includes the indication of the number of non-zero amplitude parameters and the set of location bits. The transceiver transmits the CSI to the base unit.
