    Abstract: A wireless access node (e.g. a master eNB (MeNB)) is described for a wireless communication system that comprises a first wireless access network and a second wireless access network supporting a dual connectivity terminal device arranged to communicate with both the wireless access node (MeNB) on the first wireless access network and a second wireless access node (e.g. a secondary eNB (SeNB)) on the second wireless access network is provided. The wireless access node comprises a communication unit and a controller. The controller is operably coupled to the communication unit and configured to control the communication unit to transmit a first message including configuration information for a secondary cell group (SCG) to perform a certain action, to the other base station, and to receive a second message in response to the first message from the other base station, and to control the communication to transmit a third message based on the second message to the terminal, wherein the configuration information includes multimedia broadcast multicast service (MBMS) interest information.

    Abstract: The present disclosure relates to a method and apparatus for transmitting data using a multi-carrier in a mobile communication system. The method of transmitting data in user equipment of a wireless communication system using a carrier aggregation technique according to an embodiment of the present disclosure includes the steps of setting secondary cells included in an S-TAG (Secondary-Timing Advance Group) configured of only secondary cells (SCells), deactivating a downlink timing reference cell in the S-TAG; determining whether other activated secondary cells exist besides the deactivated downlink timing reference cell in the S-TAG, and when the other activated secondary cells exist in the S-TAG, setting one of the other activated secondary cells as a new downlink timing reference cell. According to the present disclosure, uplink transmission speed can be increased in the user equipment and user QoS can be improved by transmitting data using one or more uplink carriers in the terminal.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE). A method for performing a measurement procedure by a user equipment (UE) in a wireless communication system supporting a dual connectivity (DC) is provided. The method includes receiving control information including measurement gap configuration information indicating gap configuration for at least one operating frequency band to which a measurement gap is applied; obtaining a system frame number (SFN) of a serving cell and a sub-frame of the serving cell based on the measurement gap configuration information; determining a first sub-frame of the measurement gap based on the SFN and the sub-frame; and performing a measurement on at least one serving cell including the serving cell at the first sub-frame.
