    Abstract: Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A communication method of a terminal in a wireless communication system, which includes a first base station supporting first wireless communication and a second base station supporting second wireless communication, can comprise the steps of: performing data communication though the first wireless communication with the first base station; receiving, from the first or second base station, configuration information for second wireless communication connection; reporting, to the first or second base station, the result of measurement on at least one beamforming reference signal having been received from the second base station, on the basis of the configuration information; and establishing the second wireless communication connection with the second base station on the basis of the measurement result.

    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.
