EFFICIENT VECTOR QUANTIZER FOR FD-MIMO SYSTEMS

摘要

Methods and apparatus for vector quantization of feedback and processing of vector quantized feedback components. A method of operating a UE for vector quantization of feedback includes identifying a grouping method for grouping channel coefficients for vector quantization and identifying a vector quantization codebook for vector quantization of grouped vectors based on one or more control signals received from an eNB. The method includes computing channel coefficients based on at least one channel measurement and grouping the computed channel coefficients according to the identified grouping method to form a set of vectors. The method also includes performing vector quantization of the vectors using the identified vector quantization codebook and processing the quantized vectors into one or more feedback signals. Additionally, the method includes transmitting the one or more feedback signals to the eNB.
