Abstract:
Systems and methods provide channel state information feedback in a multiple-input multiple-output (MIMO) system. A method quantizes a pre-coding matrix indicator (PMI) and feeds it back from a user equipment (UE) to an evolved Node B (eNodeB). The method may use codebooks for vector quantization of optimal horizontal direction and a scalar quantizer to quantize an optimal vertical direction from the eNodeB to a selected UE.
