Abstract: A traffic mobility method between heterogeneous access networks of a wireless communication system includes, as a user equipment (UE) multiply accesses a first access network and a second access network, configuring a first transmission path corresponding to the first access network and a second transmission path corresponding to the second access network with respect to the UE, by a gateway, determining whether traffic mobility is performed on each traffic flow based on a traffic mobility policy of the each traffic flow served to the UE through the first transmission path and a transmission state of the second access network, by a control entity, and changing a transmission path of a traffic flow on which traffic mobility is determined, to the second transmission path from the first transmission path, by the gateway.

Abstract: Disclosed is a wireless communication system, specifically, an apparatus and method for configuring a primary cell carrier/secondary cell carrier (PCC/SCC) prioritization only based on extremely partial channel state information in a wireless communication system. Specifically, a method of operating a user equipment (UE) in a wireless communication system includes: transmitting a sounding reference signal (SRS) or channel state information (CSI) to a base station; receiving a signal from the base station on the basis of the SRS or the CSI; and estimating a number of multi-paths using a neural network for the received signal, wherein the estimating of the number of multi-paths includes: re-shaping the received signal; extracting a singular value of the reshaped signal; and estimating the number of multi-paths based on the extracted singular value.

Abstract: Disclosed is a technique for switching from a master node to a secondary node in a communication system. A method of a first communication node may comprise: adding the first communication node as a primary secondary cell (PSCell) to a second communication node through dual connectivity (DC); generating a first user plane path for smart dynamic switching (SDS) and a first instance for supporting the first user plane path according to a request from the second communication node; transmitting information on the first user plane path and the first instance to a terminal; receiving user data based on the first user plane path from the terminal as the first instance; and transmitting the user data to a core network using the first user plane path.
