Method and apparatus for data transmission in wireless cellular communication system

A method of transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) information in a wireless communication system, the method comprising:

• receiving, from a base station, downlink control information for scheduling downlink data;
• receiving the downlink data;
• and
• transmitting, to the base station, HARQ-ACK information with respect to the downlink data,
• wherein the downlink data includes at least one code block group,
• wherein the HARQ-ACK information includes reception acknowledgement information or reception non-acknowledgement information with respect to each of the at least one code block group, and
• wherein the HARQ-ACK information is transmitted via a first resource if the HARQ-ACK information indicates that all of the at least one code block group is successfully received or reception thereof fails, and otherwise, the HARQ-ACK information is transmitted via a second resource.

A base station for receiving hybrid automatic repeat request-acknowledgement (HARQ-ACK) information in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller connected to the transceiver, and configured to perform control so as to transmit downlink control information for scheduling downlink data to a user equipment (UE), to transmit the downlink data, and to receive HARQ-ACK information with respect to the downlink data from the UE,
• wherein the downlink data includes at least one code block group;
• wherein the HARQ-ACK information includes reception acknowledgement information or reception non-acknowledgement information with respect to each of the at least one code block group;
• and
• wherein the HARQ-ACK information is received via a first resource if the HARQ-ACK information indicates that all of the at least one code block group is successfully received by the UE or reception thereof fails, and otherwise, the HARQ-ACK information is received via a second resource.

A user equipment (UE) that transmits hybrid automatic repeat request-acknowledgement (HARQ_ACK) information in a wireless communication system, the UE comprising:

• a transceiver;
• and
• a controller connected to the transceiver, and configured to perform control so as to receive downlink control information for scheduling downlink data from a base station, to receive the downlink data, and to transmit HARQ-ACK information with respect to the downlink data to the base station,
• wherein the downlink data includes at least one code block group,
• wherein the HARQ-ACK information includes reception acknowledgement information or reception non-acknowledgement information with respect to each of the at least one code block group, and
• wherein the HARQ-ACK information is transmitted via a first resource if all of the at least one code block group is successfully received or reception thereof fails, and otherwise, the HARQ-ACK information is transmitted via a second resource.
