The present disclosure relates to a communication technique which combines a 5G (5th Generation) communication system, for supporting a higher data transmission rate following 4G (4th Generation) systems, with IoT (Internet of Things) technology, and to a system for the communication technique. The present disclosure may be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security, and safety-related services), based on 5G communication technology and IoT-related technology. The present invention relates to a method and device for receiving broadcast information by means of a terminal in a communication system. The method for receiving broadcast information by means of a terminal in a communication system according to an embodiment of the present invention comprises the processes of: receiving a signal including broadcast information from a base station; using a repeating pattern of the signal and determining a value for autocorrelation; determining whether coverage enhancement is supported by the base station on the basis of the value for the autocorrelation; acquiring the broadcast information through decoding of the signal when the base station supports coverage enhancement; and moving to another cell or another center frequency and implementing initial connection when the base station does not support coverage enhancement.
