Abstract: A method, performed by a wireless device is described. The method is for handling a failure in a secondary cell serving the wireless device. The secondary cell and a primary cell serve the wireless device with carrier aggregation (CA) in a wireless communications network. The wireless device determines the failure in the secondary cell. The determination is based on a determination of a radio link control failure. The wireless device initiates sending an indication to a network node. The network node is one of a first network node and a second network node. The indication is based on the determined failure of the secondary cell. A method, performed by the network node is also described. The network node receives the indication and initiates a second procedure.

Abstract: Systems, methods and apparatus are disclosed for user equipment and network nodes.An example method performed by a user equipment (UE) includes the UE detecting a failure relating to a connection between the UE and a Master Cell Group (MCG). The UE provides, to a master node via a Secondary Cell Group, SCG, a first message relating to the detected failure. The UE receives, from the master node via the SCG, a second message indicating to the UE to perform a connection reconfiguration.An example method performed by the master node includes the master node receiving, from the UE via the SCG, the first message including information relating to the detected failure of the connection between the UE and the MCG. The master node determines, based on the first message and a user equipment context, to perform a connection reconfiguration. The master node provides, to the UE via the SCG, the second message indicating to perform the connection reconfiguration.
