Abstract
Methods and apparatuses for channel state information reporting in advanced MIMO antenna systems is provided. The method comprises: receiving information for an analog beam and an R CSI-RS resources; constructing an analog beam codebook; deriving sets of PMIs corresponding to analog beams, wherein each set of R sets of PMIs corresponds to an analog beam of the analog beams associated with the R CSI-RS resources; identifying a set of digital beams corresponding to each of the analog beams; identifying a set of hybrid beams corresponding to each of the R CSI-RS resources, wherein the set of the hybrid beams comprises the set of digital beams and the analog beam, respectively; identifying a subset of the set of hybrid beams using an index to generate a PMI corresponding to the analog beams; and transmitting a CSI report including the PMI and the subset of the set of hybrid beams.
