Patent ID: 11929800
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A base station (BS) comprising:
a processor configured to generate 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 transceiver operably coupled to the processor, the transceiver configured to:
transmit the configuration information; and

receive the UL transmission on the allocated resources using an UL precoding matrix, wherein the UL precoding matrix is based on the update precoding matrix V and a previous 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.
