  • Patent number: 11968571
    Abstract: A method performed by a target node (111) in a communications network (100). The method is for handling reconfigurations of a User Equipment (UE) (120) during a conditional handover. The target node (111) has received a conditional handover request for the UE (120) from a source node (110) and has sent a handover request acknowledgement to the source node (110) based on a current configuration of the UE (120). The target node (111) performs (401) synchronization and random access with the UE (120) based on the UE configuration used for the handover request acknowledgement. The target node (111) obtains (403), after performing (401) the synchronization, information regarding an updated configuration of the UE (120). The updated configuration has taken place since the handover request acknowledgement was sent to the source node (110).
