    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for processing a packet by a transmission device in a wireless communication system according to an embodiment of the present invention comprises the steps of: checking whether a data radio bearer (DRB) mapped to a quality of service (QoS) flow changes from a first DRB to a second DRB; and when the DRB changes from the first DRB to the second DRB, transmitting, to a reception device, information on a last packet transmitted through the first DRB in the QoS flow.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. According to one embodiment of the present invention, provided is a method for a terminal transmitting a data packet in a wireless communication system. The method comprises the steps of: generating a data packet; determining whether to perform duplicate transmission for the data packet; and if it is determined to perform duplicate transmission for the data packet, generating at least two duplicate packets by duplicating the data packet, and transmitting the respective at least two duplicate packets to at least two base stations.

    Abstract: The present invention relates to a method and apparatus for synchronization between electronic devices and, more particularly, to a synchronization method and apparatus for wireless communication between electronic devices. As a synchronization method for an electronic device performing wireless communication with other electronic devices, the method may include: checking, when two or more reference synchronization signals are received within a preset period, whether the received reference synchronization signals are synchronized; determining, when the received reference synchronization signals are not synchronized, to operate as a device sending a reference synchronization signal of a class lower than or equal to that of the lowest class reference synchronization signal among the received reference synchronization signals; sending a reference synchronization signal at a preset time in a synchronization frame designed to preserve temporal orthogonality between classes; and performing synchronization between reference synchronization signals in cooperation with different devices having sent reference synchronization signals.
