Classification: CPC H | IPC H

Claim 14:
15. A method for operating a user equipment (UE), the method comprising:
receiving 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;

based on the uplink precoding information, applying uplink precoding for the G antenna port groups; and
performing uplink transmission on the allocated resources according to the configuration information.
