An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: operate the apparatus in a dual connectivity mode, wherein the apparatus is in communication with a master cell group comprising a primary cell and at least one secondary cell and the apparatus is in communication with a secondary cell group comprising a primary cell and at least one secondary cell; detect a radio link failure between the apparatus and the primary cell of the secondary cell group;



provide information based on the radio link failure to the primary cell of the master cell group, the information being that the radio link failure occurred on the secondary cell group while waiting for a prepared conditional cell change from the primary cell of the secondary cell group to be fulfilled.
