A method is provided for performing handover of at least a first User Equipment from a first cell to a second cell in case of failure of the first cell.The first cell is controlled by a first Remote Radio Unit connected to a Main unit, and the second cell is controlled by a second Remote Radio Unit connected to the Main Unit, and the second cell has the same or a larger coverage area as the first cell. The method comprises the steps of monitoring the state of the connection between the first Remote Radio Unit and the Main Unit, and sending handover information to the User Equipment through the second cell using resources assigned for control signalling in said first cell, if the state of the connection between said first Remote Radio Unit and said Main Unit indicates that said first Remote Radio Unit has ceased to be functional
