Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a base station in a communication system is provided. The method includes receiving a packet including metadata from a user plane function (UPF), identifying a packet delay budget (PDB) for a quality of service (QoS) flow of the packet, identifying a delay time of the packet based on the metadata, determining an access network (AN) PDB based on the PDB and the delay time, and performing scheduling for transmission of the packet to a terminal based on the AN PDB.

Abstract: An image processing apparatus, including: at least one processor; and a memory configured to store one or more instructions which, when executed by the at least one processor, cause the image processing apparatus to: obtain a neural network model for performing image quality processing on an input image; calculate a plurality of gradients by partially differentiating weights of the neural network model with respect to a loss of the neural network model, by applying training data corresponding to the input image to the neural network model; remove at least one gradient from among the plurality of gradients by applying a gradient mask including gradient pruning information to the plurality of gradients; train the neural network model by updating the weights of the neural network model based on one or more remaining gradients from among the plurality of gradients; and obtain a quality-processed output image based on the input image, using the trained neural network model

Abstract: The present disclosure relates to: a communication technique merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. The present disclosure provides a method for introducing a service based interface (SBI) even to a base station in a wireless communication system.

Abstract: The present disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a data transmission rate higher than that of a long term evolution (LTE) communication system. The present disclosure relates to a method performed by means of a network node in a communication system, and the method may comprise the steps of: acquiring information about a packet-processing rule from a control plane network function; receiving an Internet protocol (IP) packet through a data network, the IP packet including external quality of service (QOS) information between a source node for the IP packet and the network node; generating, on the basis of the packet-processing rule and the external QoS information, QoS requirements for an IP flow including the IP packet; and allocating resources for the IP flow on the basis of the QoS requirements.

Abstract: The disclosure relates to a 5th generation (5G) communication system or a 6th generation (6G) communication system for supporting higher data rates beyond a 4th generation (4G) communication system such as long term evolution (LTE). A method performed by a user equipment in a wireless communication system is provided. The method includes generating a first non-access stratum (NAS) message including address information of the user equipment, address information of a network function (NF) entity, and name information of a service requested by the user equipment from the NF entity, transmitting the first NAS message to the NF entity via a base station, receiving a second NAS message in response to the first NAS message, from the NF entity via the base station, and the address information of the user equipment wherein the address information of the NF entity are configured by a radio resource control (RRC) message received from the base station.
