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.
