Abstract: A gap determining method includes: A terminal device receives first configuration information and second configuration information from a network device. The terminal device receives scheduling information from the network device. The terminal device determines a downlink gap of the first channel based on the first configuration information. The terminal device determines a first gap between the N transport blocks based on the second configuration information. When the terminal device determines that a preset condition is satisfied, the terminal device determines that a gap part that is included in the first gap and that overlaps with the downlink gap is postponed in time domain and that a gap part obtained through postponing does not overlap with the downlink gap; or when the first gap includes a gap part that overlaps with the downlink gap, the terminal device determines that the gap part belongs to the downlink gap.

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.
