摘要
A wireless device receives, from a first base station, at least one radio resource control (RRC) message. The at least one RRC message comprises master cell group (MCG) configuration parameters of a primary cell (PCell) of the first base station and secondary cell group (SCG) configuration parameters of a primary SCG cell (PSCell) of a second base station, for dual connectivity of the wireless device with the first base station and the second base station. The wireless device determines a failure of the PCell before the PSCell configuration is applied. Based on the failure of the PCell, the wireless device performs a cell selection. In response to the selected cell being the PSCell, the wireless device synchronizes with the PSCell based on the SCG configuration parameters.
