Method and apparatus for transmitting precoding coefficients

A transceiver can transmit a codebook subset restriction configuration including a set of restricted beams. A channel state information report including a plurality of sets of quantized coefficients based on the codebook subset restriction configuration can be received. A set of quantized weights can be based on a least a Fourier transform of a set of quantized coefficients of the particular restricted beam. The plurality of sets of quantized coefficients can be based on quantized weights of the particular restricted beam satisfying a constraint. The plurality of sets of quantized coefficients can be further based on a set of coefficients quantized to determine the plurality of sets of quantized coefficients. The set of coefficients can be generated by transforming a set of beam weights from a frequency domain to a time domain, where the beam weights correspond to a transmitted beam.
