20140286218 | METHOD AND APPARATUS FOR TRANSMITTING LIST OF BEARERS IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting a list of bearers in a wireless communication system is provided. A first eNodeB (eNB) of an energy saving cell configures a list of minimum required evolved-UMTS terrestrial radio access network (E-UTRAN) radio access bearers (E-RABs) or required E-RABs, and transmits the configured list of minimum required E-RABs or a required E-RABs to a second eNB of a compensation cell. Upon receiving the configured list of minimum required E-RABs, the second eNB checks whether the compensation cell is able to provide all E-RABs included in the list of minimum required E-RABs or not. Upon receiving the configured list of required E-RABs, the second eNB checks whether the compensation cell is able to provide E-RABs included in the list of required E-RABs or not. | 09-25-2014 |
20150023319 | METHOD AND APPARATUS FOR TRANSMITTING USER EQUIPMENT GROUP INFORMATION IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting user equipment (UE) group information in a wireless communication system is provided. A source eNodeB (eNB) of a handover procedure transmits a handover request message including UE group information to a target eNB of the handover procedure when the source eNB hands over a UE to the target eNB. The UE group information is included in a UE history information IE (information element) of the handover request message. | 01-22-2015 |
20150124748 | METHOD AND APPARATUS FOR PERFORMING DUAL-CONNECTIVITY OPERATION IN HETEROGENEOUS NETWORK - The present disclosure relates to a method of performing a dual-connectivity operation in a heterogeneous network by a first base station, the method comprising: transmitting to the second base station a first message to request that the second base station assign a radio resource for a specific E-RAB (E-UTRAN Radio Access Bearer); receiving from the second base station an ACK responsive to the first message; transmitting to the terminal an RRC reconfiguration message for applying a new radio resource configuration to the terminal; receiving from the terminal an RRC reconfiguration complete message to inform that the terminal's radio resource reconfiguration is complete; and transmitting to the second base station a second message to inform that the terminal's radio resource reconfiguration is successfully complete. | 05-07-2015 |
20150146596 | Method and Apparatus for Transmitting Indication in Wireless Communication System - A method and apparatus for transmitting an indication in a wireless communication system is provided. A first eNodeB (eNB) transmits an X2 setup request message or an X2 setup response message to a second eNB, receives a cell activation request message from the second eNB, and transmits a cell activation response message to the second eNB. At least one of the X2 setup request message, the X2 setup response message, and the cell activation response message includes an indication which indicates whether the first eNB supports a probing state or not. | 05-28-2015 |
20150146619 | METHOD AND APPARATUS FOR SETTING UP SCTP CONNECTION AND X2 INTERFACE IN WIRELESS COMMUNICATION SYSTEM - 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. | 05-28-2015 |
20150208289 | METHOD AND APPARATUS FOR TRANSMITTING INDICATION IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for performing a transport network layer (TNL) address discovery procedure in a wireless communication system is provided. A first eNodeB (eNB) transmits at least one of a TNL address of the first eNB and a TNL address of an X2-gateway (GW), and a source eNB identifier (ID). The eNB may further transmit an indication of X2 setup which indicates whether a direct X2 interface between the first eNB and a second eNB or an indirect X2 interface going through the X2-GW is to be set up. | 07-23-2015 |
20150327130 | METHOD AND APPARATUS FOR TRANSMITTING INDICATOR IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting an indicator in a wireless communication system is provided. According to an embodiment of the present invention, when a source eNodeB (eNB) initiates handover for a user equipment (UE), it informs a target eNB about whether the handover is to avoid in-device coexistence (IDC) interference problems or not. Alternatively, according to another embodiment of the present invention, an eNB, which the UE reestablished, informs an eNB, which radio link failure (RLF) of the UE occurred, about that the cause of UE's RLF was IDC interference. | 11-12-2015 |
20150358866 | METHOD AND APPARATUS FOR PERFORMING DUAL CONNECTIVITY IN HETEROGENEOUS NETWORK - The present invention relates to a method for performing dual connectivity operation in a heterogeneous network, which includes: transmitting a first message to a second eNB for the dual connectivity operation; and receiving a response for the first message from the second eNB, wherein the response includes E-RAB (E-UTRAN Radio Access Bearer) related information. | 12-10-2015 |
20150358972 | METHOD AND APPARATUS FOR TRANSMITTING CELL LOAD INFORMATION IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting cell load information in a wireless communication system is provided. According to an embodiment of the present invention, an eNodeB (eNB) of 3rd generation partnership project (3GPP) long-term evolution (LTE) system and a radio network controller (RNC) of universal mobile telecommunications system (UMTS) transmit cell load information via a direct path between the eNB and the RNC. According to another embodiment of the present invention, the eNB and the RNC transmit cell load information through S1 gateway. | 12-10-2015 |
