Abstract: A method of performing pairing by a transmission terminal in device to device communication is provided. The method includes classifying a plurality of link identifications for identifying a data transmission and reception channel a seed of at least one link identification; selecting an available candidate link identification seed among the seed of the at least one link identification, transmitting a pairing request message including seed information associated with the selected available candidate link identification seed, and receiving a pairing response message corresponding to the pairing request message. When allocating a connection ID in a device to device communication environment, even if a small number of devices exist, an overhead for searching for the connection ID is not great. Further, when many devices exist within a specific range, a probability of devices having the same connection ID is reduced. Accordingly, the device to device communication can be easily performed.

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.
