Classification: CPC H | IPC H

Claim 14:
15. A method for operating a user equipment (UE), the method comprising:
receiving configuration information associated with resource allocation for an uplink (UL) transmission, the configuration information indicating:
allocated resources for the UL transmission, and
UL precoding information for the UL transmission on the allocated resources, wherein the UL precoding information indicates:
an update precoding matrix V, and
basis vectors and coefficients for the update precoding matrix V;

determining an UL precoding matrix for the UL transmission based on the update precoding matrix V and a previous UL precoding matrix;
performing the UL transmission on the allocated resources using the UL precoding matrix;
indicating the coefficients for the basis vectors using a phase codebook and an amplitude codebook; and
determining a first granularity of the amplitude codebook by a scaling factor β and a second granularity of a second amplitude codebook.
