    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.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) 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 by which a terminal receives a signal in a mobile communication system, according to one embodiment of the present specification, comprises the steps of: receiving channel state information-reference signal (CSI-RS) mode information; and receiving a signal on the basis of the CSI-RS mode information. Unlike a conventional method of allowing a base station to periodically set the CSI-RS in a terminal at a predetermined position such that the terminal receives the CSI-RS and generates and reports channel state information, the present invention proposes a method by which a base station allocates, to a terminal, a reference signal transmission for enabling aperiodic generation of the channel state information for a system having various numbers of transmission antenna ports such as one, two, four, eight, twelve, sixteen or thirty-two transmission antenna ports, and receives the channel state information report. In addition, a method for transferring ZP CSI-RS and quasi co-location (QCL) information for supporting rate matching thereby is also proposed.

    Abstract: The present disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car 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 present invention relates to a method of a wireless communication system, the method comprising the steps of: receiving at least one piece of quasi co-location (QCL) configuration information including information indicating a plurality of CSI-RS resources from a base station; receiving downlink control information (DCI) including an indicator indicating one of the at least one piece of QCL configuration information; estimating channel state information on the basis of at least one CSI-RS resource among the plurality of CSI-RS resources; and receiving downlink data on the basis of the channel state information, wherein the plurality of CSI-RS resources include at least one among a periodic CSI-RS resource, a semi-persistent CSI-RS resource, and an aperiodic CSI-RS resource.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) 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 managing a hybrid automatic repeat request (HARM) process of a base station in a mobile communication system according to an embodiment of the present disclosure includes confirming whether a first data corresponding to a first service and a second data corresponding to a second service collide with each other. The method also includes determining whether to toggle a new data indicator (NDI) based on a modulation and coding scheme (MCS) index and the number of physical resource block (PRB) if it is determined that the first data and the second data collide with each other and retransmitting the NDI and the first data according to the determination result.
