The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure relates to the retransmission in wireless communication system. A method of operating a base station comprises transmitting resource configuration information related to a resource for an initial transmission and a resource for a retransmission to a terminal, receiving initially-transmitted data through a first resource, and receiving retransmitted data through a second resource, if a decoding of the initially-transmitted data fails. The second resource is determined based on the first resource and the resource configuration information.
