Abstract: A communication method, an access point and a station are provided. The method includes: receiving, by an access point, a sending request sent by a first station, and sending clear to send information to the first station; when the access point receives feedback information sent by the first station, allocating, by the access point, a channel to the first station, and allocating a channel to a second station based on remaining bandwidth; generating a first trigger frame, and sending the first trigger frame to the first station and the second station; and receiving uplink data sent by the first station and the second station.

Abstract: When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.

Abstract: This application provides a data communications method and apparatus. The method includes: A first station (STA) receives time adjustment information, where the time adjustment information is used to indicate a sending moment at which a signal is sent by using each of at least two beams. The first STA may send data at a corresponding sending moment based on the time adjustment information using a corresponding beam. In this way, an access point (AP) can simultaneously receive data sent by one station using at least two beams. This ensures data validity and improves data communication efficiency.

Abstract: A channel state information transmission method, where a responder receives a channel measurement signal sent by an initiator by using one or more transmit antennas, and the responder sends a feedback frame to the initiator based on the channel measurement signal. The feedback frame includes information used to indicate a transmit antenna subset of the initiator and one or more channel state information blocks of a channel between the corresponding transmit antenna subset of the initiator and the responder, where the transmit antenna subset is determined from one or more transmit antennas by using which a channel measurement signal is sent.

The method includes: generating, by a station, a backoff counter value; then performing, by the station, a backoff operation after receiving a first trigger frame, where the backoff operation includes: deducting, from the backoff counter value, a quantity N of subchannels for random access, to obtain a new backoff counter value; and when the new backoff counter value is 0 or a negative number, randomly selecting, by the station, one subchannel from the subchannels for random access, and then accessing the subchannel to send an uplink frame. The present application further provides a corresponding channel access apparatus. Applying the method and the apparatus of the embodiments of the present application improves system access efficiency and avoids a waste of system resources.
