Classification: CPC H | IPC H

Claim 17:
18. A device configured to transmit Hybrid Automatic Repeat Request (HARQ) acknowledgement information based on code block groups (CBGs) each comprising at least one code block (CB), the device comprising:
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
receiving, during a first HARQ process, a first Transport Block (TB) comprising a plurality of CBGs;
transmitting a first HARQ-Acknowledgement (ACK) response including ACK for each of at least one first CBG that is correctly decoded in the first TB, and Negative-ACK(NACK) for each of at least one second CBG that is 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; 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, for the first HARQ process: 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.
