Abstract: An uplink multi-user multi-input multi-output establishment method includes broadcasting, by a network side device, an uplink data sending announcement; receiving buffer information sent by a terminal that needs to send data, where the buffer information includes at least a sending level and a data sending length of to-be-sent data; determining, according to the buffer information, scheduling information for establishing uplink multi-user multi-input multi-output; and sending, to a terminal that is allowed to send data and selected from the terminal that needs to send data, a clear to send frame that carries the scheduling information, so that the terminal that is allowed to send data sends the to-be-sent data according to the scheduling information. The embodiments of the present disclosure effectively implement uplink multi-user multi-input multi-output establishment, so that signaling interworking is reduced, resource overheads are reduced, and data sending efficiency is improved.

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.

Abstract: A channel access method is provided. Under the method, a network element performs random backoff listen before talk (LBT) for channel preemption, and after the preemption succeeds, performs signal transmission in the first transmission time interval TTI within a maximum channel occupancy time MCOT. The network element also performs nonrandom backoff LBT for channel preemption before another at least one TTI within the maximum channel occupancy time MCOT. This is to ensure coexistence and performance of systems when an LBT requirement of a high unlicensed frequency band is met.
