7. The method of claim 6 , wherein performing the HARQ ACK/NACK transmission further comprises:
determining whether an interruption regarding the first type data is generated, based on the interruption indicator; and
when the interruption regarding the first type data is generated, determining to change the pre-configured HARQ ACK/NACK transmission resource to the new HARQ ACK/NACK transmission resource.
8. The method of claim 6 , wherein performing the HARQ ACK/NACK transmission further comprises determining to change the pre-configured HARQ ACK/NACK transmission resource to the new HARQ ACK/NACK transmission resource at least one of when a time difference between a reception time of the interruption indicator and at least one of a reception time of the first type data, a reception time of the second type data, and a transmission time of HARQ ACK/NACK is equal to or greater than a threshold value and when a resource to which a demodulation reference signal (DMRS) for demodulation of the first type data is assigned is interrupted.
9. The method of claim 6 , wherein the new HARQ ACK/NACK transmission resource comprises a time resource different from the pre-configured HARQ ACK/NACK transmission resource.
10. A terminal for transmitting and receiving control information in a wireless communication system, the terminal comprising:
a communicator configured to communicate with a base station; and
a processor configured to receive first type data in a scheduled downlink physical data channel resource region, receive second type data assigned to at least a part of a resource region assigned to the first type data, receive an interruption indicator for verifying the second type data is received, and perform a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) transmission regarding the first type data based on the interruption indicator in units of at least one code block, when a resource to which at least one code block included in the first service type data is assigned is interrupted by a predetermined ratio.
11. The terminal of claim 10 , wherein the processor is further configured to determine the HARQ ACK/NACK transmission regarding the first type data based on a reception time of the interruption indicator,
wherein the reception time of the interruption indicator comprises at least one of a time when a resource region including the interruption indicator starts to be received and a time when reception of the interruption indicator is ended.
12. The terminal of claim 11 , wherein the processor is further configured to determine the HARQ ACK/NACK transmission regarding the first type data based on at least one of a reception time of the first type data, a reception time of the second type data, and a transmission time of HARQ ACK/NACK,
wherein the reception time of the first type data comprises at least one of a time when a resource region to which the first type data is assigned starts to be received and a time when reception is ended,
the reception time of the second type data comprises at least one of a time when a resource region to which the second type data is assigned starts to be received and a time when reception is ended, and
