An apparatus and a method are provided, by which a measurement gap sharing scheme is generated by sharing measurement gaps between radio link monitoring measurement, intra-frequency measurement and inter-frequency measurement based on configurations of radio link monitoring reference signals for radio link monitoring and synchronization signal blocks and/or other reference signals used for intra-frequency measurements; measurements including the radio link monitoring measurement, the intra-frequency measurement and inter-frequency measurement are performed according to the measurement gap sharing scheme, and the measurement gap sharing scheme between radio link monitoring measurement, intra-frequency measurement and inter-frequency measurement is changed based on the radio link quality of a serving cell.
