Classification: CPC H | IPC H

Claim 10:
11. An apparatus comprising:
one or more processors;
circuitry configured to receive information comprising a channel state information (CSI) configuration and a codebook configuration, the codebook configuration specifying a codebook, and to transmit a CSI report in accordance with the CSI configuration; and
a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
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, wherein the CSI report comprises the PMI, and 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.
