Abstract: The present invention is about conditional handover (CHO) in telecommunications networks, and a main point is to pass the responsibility to a target Master Node for triggering the UE to rapid access to Primary Secondary Cell after applying target Primary Cell configuration during a CHO-NR-DC handover. The target MN decides whether to wait further to execute CPC. If measurements are hopeful, completion of execution of the primary secondary cell for dual connectivity is postponed, and L3 measurement results are inspected from the UE. There are three variants, when the target MN requests the UE to access the target Secondary Node; namely RRC-based access target SN trigger, PDCCH-order-based variant and DL MCE-based variant.

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.
