Embodiments of the present disclosure provide a method for transmitting a service in a wireless communication network. The service is transmitted by a terminal device to a base station. The terminal device receives from the base station, information of a correspondence between a data radio bearer (DRB) and a radio interface technology supported in a frequency range of a cell. The frequency range is one of N frequency ranges, wherein N≥2. The terminal device also receives characteristic information of the radio interface technology, which includes a subcarrier spacing. The terminal device transmits the service on the DRB within the frequency range using the subcarrier spacing of the radio interface technology.
