Abstract: Methods and devices in a wireless communication system are provided. Information on a number of code block group per transport block (TB) is received from a base station. Each code block group includes at least one code block. A TB and control information scheduling the TB are received from the base station. Code block groups for the TB are identified based on a number of code blocks for the TB and the information. The number of the code blocks for the TB being determined based on the control information. The TB is decoded based on the identified code block groups. Hybrid automatic repeat request (HARQ) feedback information is transmitted to the base station based on a result of the decoding.

Abstract: The present invention relates to a communication technique, which is a convergence of IoT technology and 5G communication system for supporting higher data transmission rate beyond 4G system, and a system for same. The present invention can be applied to smart services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security- and safety-related services and the like) on the basis of 5G communication technology and IoT-related technology. The present invention provides a resource allocation method by a base station comprising the steps of: comparing a transmission time interval (TTI), which is for transmitting data to a terminal, with a preconfigured transmission time interval reference value; if the transmission time interval for the data transmission is shorter than the transmission time interval reference value, determining a resource allocation type for showing frequency resources allocated for the data transmission, and generating control information on the basis of the determined resource allocation type.
