Abstract: The present invention addresses apparatuses, methods and computer program product for enabling support of legacy user equipment and legacy network elements in small cell system for LTE and beyond systems. Each small cell uses a unique pair of Physical Cell Identifier and E-UTRAN Cell Global Identifier {PCI, ECGI} in the small cell system. In a handover preparation phase, when an enhanced eNB initiates the handover request procedure, the source eNB includes the pair of {PCI, ECGI} in the handover request message. Upon the reception of the {PCI, ECGI} from the handover request message, the associated eNB determines the target small cell based on the received pair of {PCI, ECGI}.

Abstract: According to an example aspect of the present invention, there is provided a method comprising, determining, by a source base station, a first target cell and a second target cell for a handover of a user equipment, wherein the first target cell and the second target cell are cells of the same target base station, setting, by the source base station, an identifier of a first handover preparation procedure and an identifier of a second handover preparation procedure, wherein the identifier of the first handover preparation procedure is different compared to the identifier of the second handover preparation procedure, initializing, by the source base station, the first handover preparation procedure to the first target cell and the second handover preparation procedure to the second target cell and binding, by the source base station, the identifier of the first handover preparation procedure and the identifier of the second handover preparation procedure.
