    Abstract: Embodiments of this application disclose a communication method between multi-link devices and an apparatus, and relate to the field of communications technologies, to reduce power consumption of a station multi-link device. A specific solution is as follows: A multi-link device includes a plurality of STAs, one STA operates on one of a plurality of links, and the STA determines a primary link in the plurality of links. A STA operating on the primary link in the multi-link device may receive information sent by the AP indicating whether the STA operating on the primary link has a downlink traffic, and/or information indicating whether a STA operating on a link other than the primary link has a downlink traffic. Therefore, the STA operating on the primary link may determine a link on which the STA having a downlink traffic operates in the multi-link device.

    Abstract: Provided are a method and device for sending information. The method for sending information of the present invention comprises: before a sending station sends data, detecting a busy or idle condition of a channel; if the channel is in an idle state, increasing, by the sending station, the maximum time length for occupying the channel, and sending data, wherein the time length for occupying the channel when the data is sent is less than or equal to the increased maximum time length; and if the channel is in a busy state, reducing, by the sending station, the maximum time length for occupying the channel, and sending data, wherein the time length for occupying the channel when the data is sent is less than or equal to the reduced maximum time length.

    Abstract: This application relates to a communication method, a communication device, and a computer-readable storage medium. In the communication method, a second device receives a third protocol data unit from a first device. The third protocol data unit includes a second frame, and the second frame indicates that a first time period in a transmission opportunity of the first device is allocated for data transmission of the second device. The second device transmits a fourth protocol data unit to a third device within the first time period. A duration field in the fourth protocol data unit is set, so that a basic network allocation vector associated with the fourth device is 0 when the first time period ends. In this way, the fourth device can respond to triggering, thereby improving system efficiency.

    Abstract: This application discloses example device-to-device (D2D) transmission methods and communication apparatuses. One example method includes receiving, by a station, a trigger frame sent by an access point, where the trigger frame includes a user information field, the user information field includes an identifier of the station, resource allocation information, first indication information, and second indication information, the first indication information indicates that a resource unit indicated by the resource allocation information is used for D2D transmission, and the second indication information indicates that the station is a sender or a receiver of the D2D transmission. The D2D transmission is performed by the station on the resource unit indicated by the resource allocation information.

    Abstract: The present disclosure relates to communication methods, apparatus, and systems. One example method includes sending, by an access point, a first beacon frame, where the first beacon frame is used to schedule a first-type station set, a target wake time (TWT) information element in the first beacon frame includes first indication information, and the first indication information is used to indicate to the first-type station set that a first TWT service period is provided to a second-type station set for use, and sending, by the access point, a second indication frame in the first TWT service period, where the second indication frame is used to schedule the second-type station set, and a bandwidth specification of a physical packet carrying a beacon frame for scheduling the first-type station set is different from a bandwidth specification of a physical packet carrying an indication frame for scheduling the second-type station set.
