Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A user equipment (UE) comprising:
a transceiver configured to receive 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; and

a processor operably coupled to the transceiver, the processor configured, based on the update precoding matrix V and a previous UL precoding matrix, to determine an UL precoding matrix for the UL transmission,
wherein the transceiver is further configured to perform the UL transmission on the allocated resources using the UL precoding matrix,
wherein coefficients for the basis vectors are indicated using a phase codebook and an amplitude codebook, and
wherein a first granularity of the amplitude codebook is determined by (i) a scaling factor β and (ii) a second granularity of a second amplitude codebook.
