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: This application provides a synchronization signal sending method and receiving method, and an apparatus. In the method, a base station determines a frequency domain position of a target frequency resource based on a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer. The base station sends a synchronization signal by using the target frequency resource.

Abstract: A user equipment includes a processor and a non-transitory computer-readable storage medium storing a program. The program includes instructions to determine a frame structure of a serving cell. Each frame based on the frame structure comprises 2k subframes having at least: (N−1) downlink subframes, (N−1) uplink subframes, and one special subframe which is a first or second special subframe. N and k are each positive integers greater than or equal to 1. The program has instructions to send and receive information in frames based on the frame structure. Each frame has N downlink subframes, N uplink subframes, and (2k−2N) special subframes, where N is less than k, or N downlink subframes, (N−1) uplink subframes, and one second special subframe, where N is equal to k, or (N−1) downlink subframes, N uplink subframes, and one first special subframe, where N is equal to k.
