The RNN is configured to serve the first cell, the UE is located within the first cell and is served by the RNN, and RNN and the UE are comprised in a communications system (). The RNN transmits an RRCConnectionReconfiguration signal to the UE, which signal comprises an indication that the UE does not need to perform a random access procedure for the second cell when changing primary cell from the first cell to the second cell.
