    Abstract: Disclosed are a communication scheme and a system thereof for converging an IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on 5G communication technology and IoT-related technology. Disclosed is a method of a user equipment (UE) in a wireless communication system. The method includes: receiving a message including secondary cell (SCell) configuration information from a base station; identifying whether a condition for transitioning the SCell to a dormant state is satisfied; and in case that the condition for transitioning the SCell to the dormant state is satisfied, releasing periodic transmission resources for the SCell configured in the UE.

    Abstract: The present invention relates to a method for offloading traffic by means of wireless LAN in a mobile communications system and apparatus therefor, and more particularly to a method for a terminal to offload traffic at a bearer level, and to a base station communicating with the terminal. The method for a terminal to offload traffic according to the present invention includes the steps of: while performing a data communication with a base station through a bearer of a first communications network, receiving from the base station an offloading command for offloading a part of traffic to a second communications network; transmitting a report of the offloading to the base station in response to the offloading command; and performing a data communication of the partial traffic with an accessible AP through a bearer of the second communications network without releasing the bearer of the first communications network.

    Abstract: A method for configuring a flow-based quality of service (QoS), configuring a bearer-based QoS, and introducing a new layer above a packet data convergence protocol (PDCP) layer in order to process the flow-based QoS are provided. An operation of the PDCP layer to support the new layer is also provided. The disclosure relates to a communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with an Internet of things (IoT) technology. The 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 or connected car, health care, digital education, smart retail, security and safety services.
