1. A user equipment (UE), comprising:
a transceiver configured to receive information about a channel state information (CSI) report; and
a processor, operably coupled to the transceiver, configured to determine a precoding matrix indicator (PMI) indicating a total of N3 precoding matrices based on a weighted sum using L pairs (wi, ci), where i=1, . . . , L, wi corresponds to a joint basis vector across spatial and frequency dimensions, and ci corresponds to a coefficient,
wherein the transceiver is further configured to transmit the CSI report including the PMI.
