Claim 15:
16. A base station a communication system, the base station comprising:
a transceiver; and
at least one processor configured to:
transmit, to a user equipment (UE), first downlink control information (DCI) for scheduling an initial transmission of a transport block (TB) based on a new data indicator field (NDI) field of the first DCI,
transmit the TB to the UE based on the first DCI, the TB including all code block groups (CBGs) of the TB;
transmit, to the UE, second DCI for scheduling retransmission of one or more CBGs of the TB based on an NDI field of the second DCI, the second DCI including an indicator associated with the one or more CBGs for the retransmission; and
transmit, to the UE, the one or more CBGs for the retransmission according to the indicator,
wherein the downlink control information indicates whether earlier transmitted one or more CBGs are corrupted, or the retransmitted one or more CBGs are combinable with the earlier transmitted one or more CBGs.
