US 2020/0092915 A1 · DATA SENDING METHOD AND COMMUNICATIONS DEVICE

Abstract

The present invention discloses a data sending method and a communications device. The method includes: sensing, by a communications device, a carrier located in a first unlicensed frequency band, where the first unlicensed frequency band includes at least one carrier; and sending, by the communications device, data on a carrier whose channel state is sensed to be idle. The communications device senses a first carrier in the first unlicensed frequency band, and sends the data on the first carrier that is successfully sensed to be idle. Another communications device may also sense in the first unlicensed frequency band, and send data in the first unlicensed frequency band when sensing successfully. Therefore, users of different services may fairly contend and coexist in an unlicensed frequency band.

Dependent claims

A data sending method, wherein the method comprises:

sensing, by a communications device, a carrier located in a first unlicensed frequency band, wherein the first unlicensed frequency band comprises at least one carrier;
and
sending, by the communications device, data on a carrier whose channel state is sensed to be idle.

A communications device, wherein the communications device comprises a processor and a transceiver;

the processor is configured to generate data needing to be sent;
and
the transceiver is configured to sense a carrier located in a first unlicensed frequency band, wherein the first unlicensed frequency band comprises at least one carrier;
and is further configured to send the data on a carrier whose channel state is sensed to be idle.
