Claim 16:
17. The communication device of claim 1, wherein
the communication device is configured with
one or more scalar codebooks for the quantization of each entry of each basis vector of the plurality of dominant principal components of the channel tensor or the compressed channel tensor and the singular values or high order singular values, or
with one or more unit-norm vector codebooks for the quantization of each basis vector of the plurality of dominant principal components of the channel tensor or the compressed channel tensor, and wherein the communication device selects for each basis vector a codebook vector to represent the basis vector, and

the communication device is configured to report the indices corresponding to the selected entries in the scalar or vector codebook as a part of the CSI report to the transmitter.
