Abstract: A communication method and system are provided for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. A method by a base station in a wireless communication system includes transmitting, to a terminal, first information related to a number of code block groups (CBGs) included in a transport block (TB), wherein the first information is transmitted to the terminal by radio resource control (RRC) signaling; determining CBGs for the TB based on a number of code blocks (CBs) included in the TB and the first information, wherein the determined CBGs include a first group of a first number of CBs and a second group of a second number of CBs, and wherein the first number of CBs and the second number of CBs are determined based on dividing of the number of CBs included in the TB by the number of CBGs associated with the first information; transmitting, to the terminal, the determined CBGs and control information including second information related to transmission of the TB and third information; and receiving, from the terminal, feedback information for the TB transmitted based on the determined CBGs.
