Abstract
A data sending method includes determining, by user equipment, a narrowband time-frequency resource scheduled by a base station. The method further includes performing, by the user equipment, clear channel assessment CCA channel detection on the narrowband time-frequency resource to obtain a channel energy value of the narrowband time-frequency resource. The method further includes determining, by the user equipment, whether the channel energy value is less than a preset energy threshold. When the channel energy value is less than the preset energy threshold, the method includes sending, by the user equipment, uplink data to the base station on the narrowband time-frequency resource.
