A first wireless device receives from a first base station, configuration parameters of one or more beams of a first cell of the first base station. The first wireless device determines a connection failure with the first cell based on considering at least one criterion during a period of time in which the first wireless device employs at least a first beam of the one or more beams. The first wireless device selects a second cell of a second base station in response to the connection failure. The first wireless device transmits to the second base station, a first message comprising a radio link failure report. The radio link failure report comprises: a first beam identifier of the first beam; and a first cell identifier of the first cell.
