Claim 10:
11. A user equipment (UE) in a communication system, the UE comprising:
a transceiver; and
at least one processor configured to:
receive, from a base station, 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;
receive the TB from the base station based on the first DCI, the TB including all code block groups (CBGs) of the TB;
receive, from the base station, 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;
identify one or more CBGs for the retransmission based on the indicator; and
receive, from the base station, one or more retransmitted CBGs,
wherein the downlink control information indicates whether earlier received one or more CBGs are corrupted, or the retransmitted one or more CBGs are combinable with the earlier received one or more CBGs.
