wherein retransmission of the punctured code blocks of the plurality of code blocks is received based on a first redundancy version value, and

wherein retransmission of non-punctured code blocks is received using a second redundancy version value.

2. The method according to claim 1 , wherein the puncturing information includes information indicating which code blocks of the plurality of code blocks have been punctured.

3. The method according to claim 1 , wherein the first redundancy version value is equal to a redundancy version value used for initial transmission of the data.

4. The method according to claim 1 , further comprising receiving first control information indicating retransmission of the punctured code blocks and second control information indicating retransmission of the non-punctured code blocks,

wherein the first control information includes information on the first redundancy version value and the second control information includes information on the second redundancy version value.

5. A receiving device configured to receive data, the receiving device comprising:

a radio frequency (RF) unit; and

a processor configured to control the RF unit,

wherein the processor is configured to control the RF unit to receive a plurality of code blocks corresponding to the data and receive puncturing information indicating whether the plurality of code blocks include punctured code blocks,

wherein the processor controls the RF unit to further receive retransmission of the plurality of code blocks,

wherein the processor receives retransmission of the punctured code blocks of the plurality of code blocks by using a first redundancy version value, and

wherein the processor receives retransmission of non-punctured code blocks by using a second redundancy version value.

6. The receiving device according to claim 5 , wherein the processor controls the RF unit to receive first control information indicating retransmission of the punctured code blocks and second control information indicating retransmission of the non-punctured code blocks, and

wherein the first control information includes information on the first redundancy version value and the second control information includes information on the second redundancy version value.

7. The receiving device according to claim 5 , wherein the puncturing information includes information indicating which code blocks of the plurality of code blocks have been punctured.

8. The receiving device according to claim 5 , wherein the first redundancy version value is equal to a redundancy version value used for initial transmission of the data.

9. A method for transmitting data by a transmitting device, the method comprising:

transmitting a plurality of code blocks obtained from the data;

receiving puncturing information indicating whether the plurality of code blocks include punctured code blocks; and

performing retransmission of the plurality of code blocks,

wherein the retransmission of the punctured code blocks of the plurality of code blocks is based on a first redundancy version value, and

wherein retransmission of non-punctured code blocks is based on a second redundancy version value.

10. The method according to claim 9 , further comprising transmitting first control information indicating retransmission of the punctured code blocks and second control information indicating retransmission of the non-punctured code blocks,

wherein the first control information includes information on the first redundancy version value and the second control information includes information on the second redundancy version value.

11. The method according to claim 9 , wherein the first redundancy version value is equal to a redundancy version value used for initial transmission of the data.

12. The method according to claim 9 ,

wherein the puncturing information includes information indicating which code blocks of the plurality of code blocks have been punctured.

13. A transmitting device configured to transmit data, the transmitting device comprising:

a radio frequency (RF) unit; and

a processor configured to control the RF unit,

wherein the processor is configured to control the RF unit to transmit a plurality of code blocks obtained from the data and transmit puncturing information indicating whether the plurality of code blocks include punctured code blocks,

wherein the processor is configured to control the RF unit to perform retransmission of the plurality of code blocks,

wherein the retransmission of the punctured code blocks of the plurality of code blocks is based on a first redundancy version value, and

wherein retransmission of non-punctured code blocks is based on second redundancy version value.

14. The transmitting device according to claim 13 ,

wherein the puncturing information includes information indicating which code blocks of the plurality of code blocks have been punctured.

15. The transmitting device according to claim 13 , wherein the processor is configured to control the RF unit to transmit first control information indicating retransmission of the punctured code blocks and second control information indicating retransmission of the non-punctured code blocks, and
