1. A method of receiving, by a base station (BS), Hybrid Automatic Repeat Request (HARQ) acknowledgement information based on code block groups (CBGs) each comprising at least one code block (CB), the method comprising:
transmitting, during a first HARQ process, a first Transport Block (TB) comprising a plurality of CBGs;
receiving a first HARQ-Acknowledgement (ACK) response including ACK for each of at least one first CBG of the first TB, and Negative-ACK (NACK) for each of at least one second CBG of the first TB;
determining, based on the first HARQ-ACK response, that the at least one first CBG indicated as ACK is correctly delivered and the at least one second CBG indicated as NACK is not correctly delivered;
transmitting, during the first HARQ process, a second TB comprising the at least one second CBG as a CBG-based retransmission of the first TB; and
receiving, in response to transmitting 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 the CBG-based retransmission and (ii) ACK for each of the at least one first CBG that was indicated as ACK by the first HARQ-ACK response,
wherein, based on that once the at least one first CBG was correctly delivered through the first TB, ACK is to be received by the BS for the at least one first CBG until an end of the first HARQ process.
