Feedback overhead reduction for precoders under high rank spatial channels

Apparatuses, systems, and methods for a wireless device to encode channel state information (CSI), e.g., enhanced type II CSI. A common frequency basis may be selected. Spatial-frequency coefficients, frequency basis related information, and/or spatial basis related information may be determined. At...

More Information
Summary:Apparatuses, systems, and methods for a wireless device to encode channel state information (CSI), e.g., enhanced type II CSI. A common frequency basis may be selected. Spatial-frequency coefficients, frequency basis related information, and/or spatial basis related information may be determined. At least a portion of the coefficients and/or information may be encoded in a CSI report.
