1. A data sending method, comprising:
sensing, by a communications device, a first carrier located in a first unlicensed frequency band using a first sensing mechanism, wherein the first unlicensed frequency band comprises at least one carrier, the first unlicensed frequency band comprises a guard band to prevent mutual interference;
sensing, by the communications device, a second carrier in the first unlicensed frequency band using a second sensing mechanism, wherein a start time of sensing the second carrier using the second sensing mechanism is configured, such that an end time of sensing the second carrier using the second sensing mechanism is not later than an end time of sensing the first carrier using the first sensing mechanism; and
sending, by the communications device, data on a carrier whose channel state is sensed to be idle.
