Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for a handover of a coordinated multi-point connection. For example, certain embodiment may transfer a first coordinated multi-point connection (e.g., a further enhanced multiple input multiple output (FeMIMO) connection) to a second coordinated multi-point connection where the network may instruct the UE to not perform at least one random access procedure. The first coordinated multi-point connection may be controlled by a first cell (the serving cell) where the UE is ready to receive from and transmit to a first set of cells that comprises the serving cell and one or more non-serving cells. After handover, the second coordinated multi-point connection may be controlled by a previous non-serving cell, and the UE may be ready to receive from and transmit to a second set of cells that comprises the previous non-serving cell.
