    Abstract: A multi-link aggregation transmission method and a related apparatus. The method includes: a receive end receives at least one of a data frame and a BAR frame over a plurality of links between the receive end and a transmit end, where the plurality of links includes a first link. The receive end receives a block acknowledgment request BAR frame over the first link, where the BAR frame carries SSN_1 corresponding to the first link. The receive end adjusts, based on SSNs corresponding to all the links, a value of a current starting sequence number WinStart of a scoreboard window. The receive end processes, based on the adjusted WinStart, a data frame received over the plurality of links. The receive end can adaptively adjust the WinStart.

    Abstract: A resource unit combination indication method and a communication apparatus are provided. The resource unit combination indication method includes: A transmit end generates a physical layer protocol data unit (PPDU), and sends the PPDU. The PPDU includes a resource unit allocation subfield. The resource unit allocation subfield indicates a multi-resource unit (MRU) to which a 242-tone resource unit (RU) corresponding to the resource unit allocation subfield belongs, and further indicates a quantity of user fields corresponding to the resource unit allocation subfield. According to the application, one or more users may be indicated to use a plurality of contiguous or noncontiguous RUs for data transmission, to improve RU allocation flexibility of a system and spectrum utilization of the system.

    Abstract: This application provides a channel access indication method and device. The method includes: receiving, by a first communications device, a channel synchronization request sent by a second communications device, where the channel synchronization request is used to request the first communications device to send a synchronization frame to the second communications device, and a wake-up receiver is configured for the second communications device; and according to the channel synchronization request and a time at which the second communications device is woken up and that is learned by the first communications device based on preset signaling, sending, by the first communications device when a channel is idle, the synchronization frame to the woken-up second communications device, where the synchronization frame is used to instruct the woken-up second communications device to access the channel after receiving the synchronization frame.
