Abstract: 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.

Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate in comparison to the 4G communication system, such as long term evolution (LTE). A method for a terminal to establish synchronization with another terminal in a network supporting device-to-device (D2D) communication is provided. The method includes scanning, at the terminal, for synchronization signals from at least one base station, acquiring, when a synchronization signal is received from a base station, synchronization with the base station based on the synchronization signal, measuring power of the synchronization signal received from the base station, and transmitting, when data to be transmitted are generated in idle mode and the received signal power is less than a received signal power, a synchronization signal as a synchronization relaying terminal.
