Abstract:
Embodiments of an enhanced Node B (eNB) and method for precoding with reduced quantization error are generally described herein. In some embodiments, first and second precoding-matrix indicator (PMI) reports may be received on an uplink channel and a single subband precoder matrix may be interpolated from precoding matrices indicated by both the PMI reports. Symbols for multiple-input multiple output (MIMO) beamforming may be precoded using the interpolated precoder matrix computed for single subband for a multiple user (MU)-MIMO downlink orthogonal frequency division multiple access (OFDMA) transmission. In some embodiments, each of the first and second PMI reports includes a PMI associated with a same subband that jointly describes a recommended precoder.
