Abstract: A method and apparatus for performing trace recording in a wireless communication system is provided. It is assumed that an evolved NodeB (eNB) is shared by a first operator and a second operator. The UE receives an indication, which allows collecting minimization of drive tests (MDT) logs of a user equipment (UE) of the second operator, from a mobility management entity (MME) of the second operator. Upon collecting the MDT logs, the UE transmits a trace record based on the collected MDT logs to a trace collection entity (TCE) of the first operator.

Abstract: The present document is for a wireless communication with reduced internal signaling burden in the distributed antenna system (DAS). In the proposed method, a user equipment (UE) receives signals, from the network, by multiple distributed unit (DUs) distributed within the UE, wherein the multiple DUs comprise one or more main DUs and one or more sub DUs; reports, by the sub DUs, first reception information of the signals to one of the main DUs; reports, by the one of the main DUs, second reception information of the signals to a central unit (CU) controlling the multiple DUs based on the first reception information of the signals; and determines, at the CU, which one or more DUs among the multiple DUs are to transfer the received signals to the CU based on the second reception information of the signals.

Abstract: A method and apparatus for establishing/modifying/releasing data radio bearers (DRBs) in a wireless communication system is provided. A master eNodeB (MeNB) in dual connectivity transmits a request message, which includes information on E-UTRAN radio access bearers (E-RABs) to be set up/modified/released, to a secondary eNB (SeNB) in dual connectivity through an X2 interface;\, and receives a response message, which includes radio resource control (RRC) connection reconfiguration related information based on the E-RABs to be set up/modified/released, as a response to the request message from the SeNB through the X2 interface.

Abstract: In a method for providing an GCSE (Group Communication Service Enabler) service in a wireless communication system, the present invention provides a method for switching from MBMS to unicast service, comprising providing a GCSE (Group Communication Service Enabler) service to a UE through MBMS (Multimedia Broadcast Multicast Services); detecting moving of the UE; receiving MBMS status information indicating whether a neighbor cell belongs to an MBSFN(MBMS Single Frequency Network) area from a MCE (Multi-cell Coordination Entity); based on the MBMS status information, checking whether a target cell of the UE is capable of providing a GCSE service through the MBMS; and transmitting the checking result to the MCE, where in case the target cell is unable to provide a GCSE service through the MBMS, the GCSE service is provided to the UE through a unicast bearer.
