Abstract
One apparatus for providing high-resolution CSI feedback includes a processor and a radio transceiver. The processor computes sets of amplitude and phase parameters for one or more matrices corresponding to a CSI codebook. Here, each matrix corresponds to one transmission layer of a multiple-layer transmission, where each matrix is comprised of one or more column vectors. The radio transceiver sends indications of the sets of amplitude and phase parameters to one or more network entities is a mobile communication network.
