Abstract:
Provided is a method for a MCE transmitting a list of cells providing a SCPTM service in a wireless communication system. A MCE may receive a cell ID list from a MME and transmit the cell ID list received from the MME to a base station. The cell ID list transmitted to the base station and the cell ID list received from the MME may be identical. Provided is a method for a base station receiving a list of cells providing a SCPTM service in a wireless communication system. A base station may receive, from a MCE, a cell ID list received from a MME, and on the basis of the cell ID list received from the MCE, perform a SCPTM service. The cell ID list received from the MCE and the cell ID list received from the MME may be identical.

The device receives event termination information from a terminal and can transmit the event termination information to a neighboring device. The terminal is provided in a vehicle for V2X communication, and the event termination information can be information indicating that an event occurring in the terminal has been terminated.
Abstract:
A method and apparatus for performing a wireless local area network (WLAN) termination (WT) addition/modification procedure in a wireless communication system is provided. For the WT addition procedure, an eNodeB (eNB) transmits a WT Addition Request message to a WT via a Xw interface, and receives a WT Addition Request Acknowledge message from the WT via the Xw interface. For eNB initiated WT modification procedure, the eNB transmits a WT Modification Request message to a WT via a Xw interface, and receives a WT Modification Request Acknowledge message from the WT via the Xw interface. For the WT initiated WT modification procedure, the eNB receives a WT Modification Required message from a WT via a Xw interface, and transmits a WT Modification Confirm message to the WT via the Xw interface. The WT is a logical node that terminates the Xw interface.
Abstract:
Provided are a method of delivering downlink signaling and a device supporting the method. According to one embodiment of the present invention, a method in which a first base station (BS) delivers downlink signaling to a user equipment (UE) in a wireless communication system includes: receiving the downlink signaling from an upper layer entity; requesting a second BS for paging on the UE; and delivering the downlink signaling to the UE via the second BS if a paging response of the UE is received from the second BS.
Abstract:
A method and apparatus for transmitting a local home network identity (LHN ID) in a wireless communication system is provided. A first evolved NodeB (eNB) transmits an X2 Setup Request message including a LHN ID of the first eNB to a second eNB, and receives an X2 Setup Response message including a LHN ID of the second eNB from the second eNB. The first eNB may determine whether or not to trigger a secondary eNB (SeNB) addition procedure according to the LHN ID of the second eNB. When it is determined that the LHN ID of the second eNB is the same as the LHN ID of the first eNB, the first eNB may trigger the SeNB addition procedure.
Abstract:
The present invention relates to a method and a device for performing cell shaping. A base station can establish a cell shaping plan on the basis of current states. The current states may be the load of the base station and the traffic space distribution of the base station. The base station transmits a first message to a neighboring base station and receives a second message from the neighboring base station in response to the first message. The first message may include the cell shaping plan, and the second message may include whether or not the neighboring base station can perform cell shaping. The base station can determine whether or not to perform cell shaping on the basis of the second message.
Abstract:
A method and apparatus for handling evolved universal terrestrial radio access network (E-UTRAN) radio access bearer (E-RAB) switch failure for dual connectivity in a wireless communication system is provided. A master evolved NodeB (MeNB) in dual connectivity receives an E-RAB modification confirm message including a list of E-RABs failed to be modified from a mobility management entity (MME). The MeNB may keep old general packet ratio service (GPRS) tunneling protocol (GTP) tunnels for the failed E-RABs, and trigger a secondary eNB (SeNB) release procedure or a SeNB modification procedure for releasing the failed E-RABs. Alternatively, the MeNB may trigger an E-RAB release procedure for releasing the failed E-RABs.
Abstract:
A method and apparatus for deciding a secondary eNB (SeNB) user equipment aggregate maximum bit rate (UE-AMBR) in a wireless communication system is provided. In one embodiment, a master evolved NodeB (MeNB) in dual connectivity receives assistant information, which includes at least one of a buffer size or load information of a SeNB, from the SeNB, and decides whether to change a SeNB UE-AMBR based on the assistant information. In another embodiment, the MeNB transmits an indication which requests change of a SeNB UE-AMBR to a SeNB, receives information related to a new SeNB UE-AMBR from the SeNB; and decides whether to change the SeNB UE-AMBR based on the information related to the new SeNB UE-AMBR.
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:
A method and apparatus for transmitting aggregated quality of service (QoS) information in a wireless communication system is provided. A first node which controls a first cell configures a combination of aggregated QoS information for each user equipment (UE) which is receiving services from the first cell, and transmitting the combination of aggregated QoS information to a second node which controls a second cell. Upon receiving information combining aggregated QoS information for each UE from a plurality of first nodes, the second node determines whether to switch off a plurality of first cells based on the received information combining aggregated QoS information for each UE.
