1. A user equipment (UE) comprising:
a transceiver configured to:
receive 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 processor operably coupled to the transceiver, the processor configured, based on the uplink precoding information, to apply uplink precoding for the G antenna port groups;
wherein the transceiver is further configured to perform uplink transmission on the allocated resources according to the configuration information.
