Patent ID: 11923944
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A base station (BS) comprising:
a processor configured to generate configuration information about resource allocation for an uplink transmission, the configuration information indicating:
allocated resources for uplink transmission, and
uplink precoding information for G antenna port groups for the uplink transmission on the allocated resources, wherein the uplink precoding information indicates:
spatial-domain (SD) basis vectors,
frequency domain (FD) basis vectors,
coefficients for (SD, FD) basis vector pairs, and
two components for the coefficients across the G antenna port groups; and

a transceiver operably coupled to the processor, the transceiver configured to:
transmit the configuration information; and
receive the uplink transmission on the allocated resources according to the configuration information based on uplink precoding applied for the G antenna port groups and based on the uplink precoding information.
