Abstract: The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system to support a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart or connected car, health care, digital education, retail business, and services associated with security and safety, or the like) on the basis of 5G communication technology and an IoT-related technology. The present invention provides a method for determining a radio link failure. The method comprises the steps of: identifying an indication of in synchronization (IS) or out of synchronization (OOS) with respect to a plurality of reception beams; starting a timer to determine a radio link failure when the indication of OOS is identified; and holding the timer when at least one of the plurality of reception beams is requested to be changed.
