Claim 0:
1. A method comprising:
receiving, at a user equipment (UE), a channel state information (CSI) configuration and a codebook configuration, the codebook configuration specifying a codebook;
determining a precoding matrix indicator (PMI) that specifies a precoding matrix associated with the codebook, wherein the precoding matrix is based on spatial-domain (SD) vectors and linear combining coefficients; and
transmitting a CSI report comprising the PMI in accordance with the CSI configuration, wherein parameters corresponding to the linear combining coefficients are reported using a plurality of bit fields in the CSI report, the parameters comprising at least an amplitude and a phase respectively reported using a first bit field and a second bit field of the plurality of bit fields.
