Abstract
Systems, devices, and techniques associated with coefficients for channel state information (CSI) reports are described. A described technique includes receiving, at a user equipment (UE), a 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 containing the PMI in accordance with the CSI configuration.
