1. A user equipment (UE) comprising
a processor; and
a transceiver operably coupled to the processor, the transceiver configured to:
transmit a UE capability information about an uplink (UL) codebook for 8 antenna ports;
receive an indication indicating a transmit precoding matrix indicator (TPMI) for a transmission of a physical uplink shared channel (PUSCH); and
transmit the PUSCH based on the indicated TPMI,
wherein the TPMI indicates a precoding matrix from the UL codebook for the 8 antenna ports, the UL codebook includes full-coherent (FC) precoding matrices comprising all non-zero entries, and an l-th column of a FC precoding matrix is associated with an l-th layer of the PUSCH transmission, and is given by

OG Complex Work Unit Math
wherein:
l∈{1, . . . , v} and v is a number of layers of the PUSCH transmission,
N1 and N2 are number of antenna ports with the same polarization in first and second dimensions, respectively,
O1 and O2 are oversampling factors in the first and second dimensions, respectively, and
S is a scaling factor.
