1. A method performed by a user equipment (UE), the method comprising:
receiving a radio resource control (RRC) configuration from a network, the RRC configuration comprising
configurations of one or more initial resource combinations supported by a configured grant uplink (UL) resource for initial transmission of data to the network, and
one or more interpretation rules to be applied by the UE for retransmission of the data to the network;
receiving a schedule of the configured grant UL resource from the network;
transmitting the data on the configured grant UL resource to the network using the one or more initial resource combinations;
receiving a downlink control information (DCI) from the network for retransmission of the data, the DCI including a schedule of a retransmission UL resource;
determining one or more retransmission resource combinations based on the one or more interpretation rules and the DCI; and
retransmitting the data on the retransmission UL resource using the one or more retransmission resource combinations,
wherein each initial resource combination and each retransmission resource combination includes a combination of resource parameters including any one or more of a sounding reference signal (SRS) resource indicator (SRI), a transmit precoding matrix indicator (TPMI), and antenna ports, wherein the DCI indicates a combination of SRI, TPMI, and antenna ports, and
wherein the one or more interpretation rules specify that the one or more retransmission resource combinations be determined based on comparisons of the SRI, TPMI, and antenna ports indicated in the DCI with the SRI, TPMI, and antenna ports of the one or more initial resource combinations configured through the RRC configuration.
