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: The present application provides a synchronization signal sending apparatus, sending method, receiving apparatus, and receiving method, and a system. The signal sending apparatus includes a determining unit and a sending unit. By using embodiments of the present invention, a synchronization signal is in a form of a differential signal, and has relatively strong frequency deviation resistance; and synchronization signals from different transmit ends satisfy a pre-determined relationship property. Therefore, when a receive end performs synchronization by using the synchronization signal, the receive end can eliminate an interfering signal by using the relationship property between the synchronization signals from the different transmit ends, so as to achieve an objective of distinguishing the different transmit ends or distinguishing signals from different cells.
