Abstract: A method performed by a User Equipment, UE, for handling a source radio link during a handover from a source access node to a target access node in a wireless communications network. The UE is triggered to perform the handover. The UE establishes Radio Link Control, RLC, entities and associated target radio link with the target access node, while keeping RLC entities and associated source radio link with the source access node. The UE checks whether a source radio link related failure has occurred. When a source radio link related failure has occurred, the UE checks the radio link related failure against a set of source radio link release UE criteria, and when one or more source radio link release UE criterion is fulfilled out of the set of source radio link release UE criteria, the UE handling the source radio link according to a predetermined rule.
