Abstract: A data transmission method in the present application includes: determining, by first UE, a frame structure in a time unit, where the frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, according to the data transmission method and the user equipment in embodiments of the present application, a frame structure in a time unit is determined. The frame structure indicates that N type-1 OFDM symbols and a GP are included in the time unit, and a subcarrier spacing of each type-1 OFDM symbol is Δf1. Therefore, when an NB-IOT system is deployed in an LTE system in an embedded manner, and when NB-IOT UE is sending data, a channel resource of the legacy LTE system can be adequately utilized, and a conflict with a legacy LTE SRS can be avoided.

Abstract: This application provides a paging method and an apparatus. In the paging method, a first core network device sends first signaling to a first device, indicating to the first device to page a terminal device. The first device may send second signaling, where the second signaling may indicate information about a first flag. The information about the first flag indicates that a type of a flag of a to-be-paged terminal device is a first type and/or a state of the flag is a first state, to determine the to-be-paged terminal device. In this way, a mechanism for paging the terminal device is provided, and there is no need to determine which terminal device is to be paged. This helps simplify the process of paging the terminal device.
