Abstract:
An apparatus of a wireless communication device operable to communicate channel state information in a wireless network can include memory and processing circuitry coupled to the memory. The processing circuitry is arranged to derive one or more principal eigen beams from received Orthogonal Frequency Division Multiple Access (OFDMA) signals, the one or more principal eigen beams having a rank greater than or equal to one. Quantized eigen beams may be derived from the one or more principal eigen beams. A bit pattern of the quantized eigen beams and at least one of a wideband channel quality indicator (CQI) or a subband CQI may be conditioned on the quantized eigen beams. Channel State Information Reference Signal (CSI-RS) may be encoded with the conditioned bit pattern for transmission to an Evolved Node-B (eNB) in the wireless network.
