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.

Abstract: A terminal starts a first timer for detecting an RLF (Radio Link Failure) when signal strength of a serving base station is lower than a reference value. The terminal triggers a handover without a TTT (Time to Trigger) for handover when signal strength of a target base station is greater than the signal strength of the serving base station by a first offset or more while the first timer is running. The terminal transmits a measurement report message regarding the signal strength of the target base station to the serving base station when a handover is triggered.
Abstract translation: 当服务基站的信号强度低于参考值时，终端启动用于检测RLF（无线链路故障）的第一定时器。 当第一定时器运行时，当目标基站的信号强度大于服务基站的信号强度时，终端触发无TTT（触发时间）的切换。 当切换被触发时，终端向服务基站发送关于目标基站的信号强度的测量报告消息。
