摘要： 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.

摘要： The disclosure relates to a communication technique for convergence of an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart cart or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The disclosure defines a mobility method for a terminal residing in a system in which transmission/reception points (TPRs), supporting solely some protocols among entire access stratum protocols comprising PHY, MAC, RLC, PDCP, and RRC, coexist in a wireless communication system. Specifically, the disclosure defines a method for dynamically changing, depending on determination by a base station, a beam and a transmission/reception point to be used for transmitting information to or receiving information from a terminal through a method in which a system using multiple beams notifies, in advance, of a measurement reference signal transmitted using transmission/reception points of different networks, to allow a terminal to select a required reception beam from a corresponding resource and measure beam information of each transmission/reception point, or a terminal transmits measured information as feedback in which each transmission/reception point is specified. Accordingly, the disclosure can provide a criterion of rapid and highly precise determination for changing a beam and a transmission/reception point and thus prevent a terminal from needlessly measuring and reporting, so as to achieve an effect of reduction in the power consumption of the terminal and reduction of delay in change of a transmission/reception point.
