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.

Abstract: For vehicle-to-everything (V2X) communication, an eNodeB (eNB) receives authorization information for a pedestrian UE which indicates whether a user equipment (UE) is authorized as the pedestrian UE. Upon receiving the authorization information for the pedestrian UE, the eNB may authorize the UE as the pedestrian UE or not according to the received authorization information, and decide a resource allocation mode for the authorized pedestrian UE.

Abstract: A method and apparatus for transmitting a cell shaping/un-shaping indication in a wireless communication system is provided. A first eNodeB (eNB) transmits a cell shaping/un-shaping indication which indicates cell shaping/un-shaping of a cell, managed by the first eNB, in an active antenna system (AAS) to a second eNB. The cell shaping means that main coverage of the cell is maintained unchanged but an edge of the cell can be adapted to load demand. The cell un-shaping means that coverage of the cell goes back to original coverage.
