The method for processing an X2 message according to one embodiment including receiving, by the gateway, an X2 setup request message and target information from a first eNodeB (eNB); transmitting, by the gateway, the received X2 setup request message to a second eNB based on the received target information; receiving, by the gateway, an X2 setup response message from the second eNB; and transmitting, by the gateway, the received X2 setup response message to the first eNB. The target information is additional information of the X2 setup request message. The first eNB is a home eNB (HeNB).
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 invention relates to a method by which a base station transmits a signal for coverage coordination in a wireless communication system and a device for the same. According to one embodiment of the present invention, a coordinating base station receives coverage related information from each of a first base station and a second base station, performs a coverage coordination procedure by using the coverage related information of the first and second base stations and transmits a signal for coverage coordination, which is determined according to the result of performing the coverage coordination procedure, to each of the first and second base stations, wherein the coverage coordination procedure includes determining whether the second base station can supplement the coverage of the first base station when the first base station switches to an idle mode.
Abstract:
A method and apparatus for transmitting an indication in a wireless communication system is provided. An eNodeB (eNB) of a first system transmits an indication, which indicates that handover of a user equipment (UE) from the eNB to a radio network controller (RNC) of a second system is a necessary handover, to the RNC. In addition, a method and apparatus for receiving an indication for inter-radio access technology (RAT) unnecessary handover in a wireless communication system is provided. An eNB of a first system transmits a request for measuring, by a UE, quality of signals from the first system, and information related to the inter-RAT unnecessary handover, and receives an indication for the inter-RAT unnecessary handover.
Abstract:
A method and apparatus for transmitting target cell information in a wireless communication system is provided. An eNodeB (eNB) transmits target cell information to an X2-gateway (GW) via an X2 setup request message or an eNB configuration update message. The target cell information may include at least one of target eNB identifier (ID), target cell ID or target radio network layer (RNL) ID.
Abstract:
A method and apparatus for transmitting an indication in a wireless communication system is provided. A source donor eNodeB (DeNB) transmits a first handover request message for a mobile relay node, to a target DeNB, and transmits a second handover request message for user equipments (UEs) attached to the mobile relay node, to a target eNB. The source DeNB transmits an indication including information on lists of UEs which can be handed over to the target eNB, to the mobile relay node, and the mobile relay node transmits a radio resource control (RRC) connection reconfiguration message indicating a UE to handover to the target eNB.
Abstract:
A method for transmitting, by a first base station, coverage modification information in a wireless communication system is discussed. The method includes transmitting, by the first base station, the coverage modification information which informs a second base station that modifying a cell managed by the first base station is planned, to the second base station, and after the first base station transmits the coverage modification information to the second base station, modifying, by the first base station, the cell managed by the first base station.
Abstract:
A method for performing a handover procedure in a wireless communication system is provided. A first eNodeB (eNB) of a 3rd generation partnership project (3GPP) long term evolution (LTE) system receives information on an access point (AP) of a wireless local area network (WLAN) system, which is located at neighborhood of a second eNB, to which data of the first eNB can be offloaded, from a user equipment (UE) or a second eNB, and decides whether to handover the UE to the second eNB based on the received information on the AP.
Abstract:
A method and apparatus for transmitting cell load information in a wireless communication system is provided. According to an embodiment of the present invention, a master eNodeB (eNB) distributes UMTS terrestrial radio access network (UTRAN) cell load response to slave eNBs. According to another embodiment of the present invention, the master eNB aggregates evolved UTRAN (E-UTRAN) cell load response of slave eNBs to a radio network controller (RNC).
Abstract:
A method for determining a radio resource control (RRC) configuration in a wireless communication system supporting dual connectivity, and an apparatus supporting the same is disclosed. The method for determining, by a base station (BS), a radio resource control (RRC) configuration in a wireless communication system supporting dual connectivity, includes transmitting, by a first BS, a first RRC configuration of a serving cell of the first BS or remained user equipment (UE) capability to a second BS configured in a UE, and receiving, by the first BS, a second RRC configuration of a serving cell of the second BS configured in the UE from the second BS. The first BS and the second BS are involved in dual connectivity for the UE, and the second RRC configuration is determined by the second BS based on the first RRC configuration or the remained UE capability.
