Abstract: A terminal is disclosed that includes a receiver that receives beamforming information relating to one or more beamformed Channel State Information - Reference Signals (CSI-RSs), the CSI-RSs corresponding to one or more Spatial Domains (SDs) or Frequency Domains (FDs). The terminal also includes a processor that determines a type of the one or more CSI-RSs, and when the type of the one or more CSI-RS is a Type II, performs a Type II port selection codebook with a beamformed CSI-RS of the one or more CSI-RSs in the SD and FD domains.

Abstract: A method of Channel State Information (CSI) feedback in a wireless communication system includes: obtaining, with a user equipment, a first value that is a beam number value; obtaining, with the user equipment, a second value that is a scaling factor value for a vector pattern of a size M; and assigning, with the user equipment, the first value and the second value across a plurality of layers. The plurality of layers are layers with a rank indicator (RI) of a value being greater than (2). The method further includes assigning, with the user equipment, the first value and the second value to layers in a given rank out of the plurality of layers. The first value and the second value are common for the layers in the given rank.
