Abstract  Abstract

Briefly, in accordance with one or more embodiments, a codebook used to provide a precoding matrix indicator and/or channel state information comprises one or more rank-1 codewords and at least one or more rank-2 codewords exhibiting a nesting property with the rank-1 codewords, and one or more rank-2 codewords not exhibiting a nesting property with the rank-1 codewords. Further, the rank-1 codewords may include at least some Discrete Fourier Transform (DFT) vectors, and at least some vectors that are optimized for a cross polarize array of antennas if the array of antennas is cross polarized. The codebook may be utilized for single-user multiple-input, multiple-output (SU-MIMO) or multi-user multiple-input, multiple-output (MU-MIMO).
