Abstract: 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.

Abstract: Embodiments of the present disclosure provide a method for transmitting and receiving a service between a terminal device and a base station. The terminal device receives radio resource configuration information and indication information from the base station. The radio resource configuration information includes frequency band information of N (N≥2) frequency ranges and characteristic information of radio interface technologies corresponding to each of the N frequency ranges. The indication information indicates a frequency range in which a physical layer resource is to be used by the terminal device to transmit and receive the service. Characteristics of the radio interface technologies include at least one of: a cyclic prefix (CP) length, a duration of an orthogonal frequency division multiplexing (OFDM) symbol, or a subcarrier spacing.

Abstract: Embodiments of the present disclosure provide a downlink synchronization method, an apparatus, and a system, and relate to the communications field, so as to reduce downlink synchronization complexity and improve downlink synchronization efficiency. According to the downlink synchronization method, a base station sends downlink synchronization reference information to UE by using dedicated signaling or a system message, where the downlink synchronization reference information is used to instruct the UE to perform downlink synchronization in a second cell by referring to a downlink synchronization channel of a first cell; and the base station sends, in the second cell according to location information of the UE, a beam including a downlink synchronization channel to the UE, where the first cell and the second cell include an overlapped coverage area. The embodiments of the present disclosure are applied to synchronization channel sending.
