    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.

    Abstract: There is provided an apparatus for a terminal, the apparatus comprising means configured to perform: receiving a message from a serving cell, wherein the message comprises a configuration for a measurement event and a configuration for a conditional handover, the configuration for the measurement event comprising a leaving condition. The means are further configured to perform, in response to measuring the leaving condition of the measurement event being met, incrementing a counter, and when it is determined that the counter has reached a threshold value, deactivating the received configuration for the conditional handover and providing a measurement report to the serving cell, the measurement report indicating that the leaving condition of the measurement event has been met.
