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.
