    Abstract: A method and apparatus to address the problems of supporting uplink positioning in mobile network is provided. The method of the terminal includes receiving a RRC message including SuspendConfig, performing state transition to RRC_INACTIVE and cell selection, determining whether to perform TYPE1-I-SRS transmission or TYPE2-I-CRS transmission based on presence and absence of srs-PosRRC-Inactive and/or srs_positioning_inactive_multi_cell in the SuspendConfig in the RRC message and performing SRS transmission based on determination.

    Abstract: A method and apparatus for secondary base station change in a mobile communication system with multiple are provided. Method for secondary node change includes transmitting to a target SN a control message requesting conditional secondary node change, receiving from the target SN a Xn message including conditional secondary node change information, transmitting to a terminal LTE DL message for conditional secondary node change, receiving from the terminal a 1st LTE UL message including a transaction identifier, receiving from the terminal a conditional reconfiguration identifier and transmitting to a source SN a control message for data forwarding.

    Abstract: A Method and Apparatus for application layer measurement reporting in RRC_INACTIVE is provided. The method includes receiving an RRC reconfiguration message from the first base station containing the first other configuration1 and the other configuration2, receiving from the first base station an RRC release message containing a suspend configuration and a first terminal identifier and a second terminal identifier, storing the application layer measurement configurations included in said first other configuration1, monitoring paging based on said suspend configuration, receiving a paging message containing said first terminal identifier, releasing said other configuration2, transmitting an RRC resume request message containing said second terminal identifier to the second base station, receiving an RRC resume message containing the second other configuration1 from the second base station, and releasing the application layer measurement configuration indicated in said second other configuration1.

    Abstract: A method and apparatus for layer 2 mobility is provided. Method for lower layer mobility includes transmitting the UECapabilityInformation to the base station, receiving a RRCReconfigruation from the base station, receiving a PDCCH order from the base station and determining the transmission power of the preamble and transmitting a preamble to the base station based on the PDCCH order. If the PDCCH order is a type1 PDCCH order, preamble transmission power is determined based on a first parameter set and pathloss of a first cell. If PDCCH order is a type2 PDCCH order, preamble transmission power is determined based on a second parameter set and a first information (CMG identifier) and a second information (transmission power related information) and pathloss of a second cell.
