A wireless device receives from a first base station, configuration parameters of a plurality of cells. The configuration parameters comprise a first cell group comprising one or more first cells for communication with the first base station, and a second cell group comprising a licensed assisted access (LAA) cell for communication with a second base station. The wireless device receives from the second base station LAA cell signals in a subframe of a plurality of subframes of the LAA cell. The wireless device determines whether the subframe is considered for radio link failure (RLF) detection based on processing the LAA cell signals. The wireless device increments a counter in response to the subframe of the LAA cell being considered for RLF detection, and the wireless device not successfully decoding a control channel in the subframe of the LAA cell. The wireless device detects an RLF based on the counter.
