The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.

摘要： 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.

摘要： This application provides a method for transmitting a wake-up packet in a communications system and a device. The communications system includes a transmit end device and a receive end device. The receive end device includes a wake-up receiver and a main transceiver. The method includes: sending, by the transmit end device, a first wake-up packet WUP to the wake-up receiver by using a first data rate; determining, by the transmit end device, a second data rate; and sending, by the transmit end device, a second WUP to the wake-up receiver by using the second data rate. The transmit end device can determine a proper data rate for sending a wake-up packet based on a specific transmission condition in a communication process, thereby improving transmission efficiency of the wake-up packet.

摘要： Methods and apparatuses of parallel data transmission are disclosed. In one embodiment, a first node generates a physical protocol data unit (PPDU) that carries indication information. The indication information is used to indicate whether a second node is allowed to perform parallel data transmission by spanning a time length of the PPDU and indicate a boundary crossing time length of the parallel data transmission. The first node is included in a first basic set service (BSS), and the second node is included in a second BSS. The first node sends the PPDU.

摘要： This application provides data transmission methods and apparatuses, to introduce a buffer status report (BSR) mechanism through multi-link (ML) cooperation, to improve performance of scheduling a station by an ML device. In an example method, a multi-link transmit end determines BSR signaling sent to a multi-link receive end, where the BSR signaling can enable the multi-link receive end to schedule a station of the multi-link transmit end over one or more links. Further, the multi-link transmit end sends the B SR signaling to the multi-link transmit end over the one or more links. This introduces a BSR mechanism through ML cooperation.

摘要： A power save method and a communication apparatus that are applied to multi-link communication. A multi-link device sends a mode switching frame to another device to notify the other device that the multi-link device is to switch a communication mode, for example, switch from a multi-link conventional communication mode to a multi-link power save communication mode, or switch from the multi-link power save communication mode to the multi-link conventional communication mode. The multi-link conventional communication mode includes a first configuration. The multi-link power save communication mode includes the first configuration and a second configuration. A quantity of links used for transmission under the first configuration is greater than a quantity of links used for transmission under the second configuration. A balance is provided between a high rate and low power consumption.
