Claim 11:
12. The method of claim 10, further comprising:
selecting the second matrix from a set of oversampled discrete Fourier transform (DFT) vectors;
reporting, to the base station, common information and individual information on an FD basis matrix tuple, associated with the second matrix, across antenna ports of the antenna modules for the collocated antenna groups, wherein the common information is a same for multiple antenna ports of the antenna modules for the collocated antenna groups and the individual information is different for each antenna port of the antenna modules for the collocated antenna groups; and
identifying a coefficient matrix tuple across antenna ports of the antenna modules to identify a concatenated matrix of the coefficient matrix tuple, wherein the concatenated matrix is represented as a sum of coefficient basis vectors and corresponding coefficients, and wherein the CSI report includes the coefficient basis vectors and the corresponding coefficients.
