1. A non-transitory medium readable by a processor and storing instructions that cause the processor to perform operations for transmitting Hybrid Automatic Repeat Request (HARQ) acknowledgement information based on code block groups (CBGs) each comprising at least one code block (CB), the operations comprising:
receiving, during a first HARQ process, a first Transport Block (TB) comprising a plurality of CBGs;
decoding the first TB;
determining, in the first TB, at least one first CBG that is correctly decoded and at least one second CBG that is not correctly decoded;
transmitting a first HARQ-Acknowledgement (ACK) response including ACK for each of the at least one first CBG that was correctly decoded in the first TB, and Negative-ACK (NACK) for the at least one second CBG that was not correctly decoded in the first TB;
receiving, during the first HARQ process, a second TB comprising the at least one second CBG as a CBG-based retransmission of the first TB;
decoding the second TB; and
transmitting, in response to receiving the second TB, a second HARQ-ACK response including (i) ACK/NACK for each of the at least one second CBG in accordance with a result of decoding the second TB and (ii) ACK for each of the at least one first CBG that was correctly decoded in the first TB,
wherein, based on that once the at least one first CBG was correctly decoded in the first TB, ACK is reported for the at least one first CBG until an end of the first HARQ process, irrespective of re-scheduling of each of the at least one first CBG.
