Abstract: A method and apparatus for allocating resources for vehicle-to-everything (V2X) message transmission in a wireless communication system is provided. For the first solution, a pre-configuration based scheme is defined and specific temporary mobile group identities (TMGIs) are defined for the V2X service. For the second solution, a multi-cell/multicast coordination entity (MCE) receives a request for radio resource, which is based on an amount of V2X messages transmitted from vehicle user equipments (UEs) or road side unit (RSU) UEs, from an eNodB (eNB) supporting V2X function or an eNB type RSU, and transmits multimedia broadcast multicast services (MBMS) scheduling information to the eNB supporting V2X function or an eNB type RSU as a response to the request for radio resource.

Abstract: A method and apparatus for performing access control and/or membership verification for dual connectivity in a wireless communication system is provided. A first evolved NodeB (eNB) transmits a closed subscriber group (CSG) membership status of a user equipment (UE) to a second eNB, which is a home eNB (HeNB), and receives at least one of a CSG identifier (ID) or a cell access mode of the second eNB from the second eNB. A mobility management entity (MME) may verify the CSG membership status of the UE and transmit the verified CSG membership status of the UE to the first eNB. And then, the first eNB transmits the verified CSG membership status of the UE to the second eNB.

Abstract: A method and apparatus for performing an inter-master eNodeB (MeNB) handover procedure without secondary eNB (SeNB) change in a wireless communication system is provided. A target MeNB decides to keep bearers of a SeNB, and transmits a handover request acknowledge message including a first indication of keeping the bearers of the SeNB to a source MeNB. The first indication may indicate that a user equipment (UE) context in the SeNB is kept. Upon receiving the handover request acknowledge message including the first indication, the source MeNB transmits a SeNB release request message including a second indication of keeping the bearers of the SeNB to the SeNB. The second indication may indicate that a UE context in the SeNB is kept.
