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: Disclosed is a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

Abstract: When a plurality of terminals share the same resources in a wireless communication system, and when control information such as acknowledgement/negative acknowledgement (ACK/NAK) information or scheduling information is transmitted, a method of efficiently performing code division multiplexing (CDM) is required to distinguish the plurality of terminals. In particular, it is necessary to develop a method by which a code sequence of CDM can be selected and used according to each cell condition. Provided is a method of forming a signal in a wireless communication system in which a plurality of terminals commonly share frequency and time resources. The method includes the operations of receiving condition information in a cell; selecting one of a plurality of time domain orthogonal sequences having different lengths, according to the condition information; and allocating the selected time domain orthogonal sequence to a control signal symbol block.
