Claim 17:
18. The BS of claim 16, wherein:
the transceiver is further configured to receive a reporting message, from the UE, 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;
the common information is a same for multiple antenna ports of the antenna modules for the collocated antenna groups;
the individual information is different for each antenna port of the antenna modules for the collocated antenna groups;
the second matrix is selected from a set of oversampled discrete Fourier transform (DFT) vectors;
a coefficient matrix tuple across antenna ports of the antenna modules to identify a concatenated matrix of the coefficient matrix tuple is identified;
the concatenated matrix is represented as a sum of coefficient basis vectors and corresponding coefficients; and
the CSI report includes the coefficient basis vectors and the corresponding coefficients.
