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: 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.

Abstract: 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.

Abstract: An access point, AP, (110) configured to communicate with a non-AP station (120) in a wireless local area network, WLAN (130). The AP (110) comprises a processing circuitry (111) configured to generate a nonce and a communication interface (113) configured to transmit a first message to the non-AP station (120). The first message (202) comprises the nonce. In response to receiving a second message from the non-AP station (120), the processing circuitry (111) is further configured to encrypt information about one or more policies. The information about the one or more policies identifies one or more policies to be applied by the non-AP station (120). The communication interface (113) is further configured to transmit a third message to the non-AP station (120). The third message comprises the encrypted information about the one or more policies.

Abstract: This application provides a communication method and a communication apparatus. In one example, a first physical layer protocol data unit (PPDU) is sent over a first link, where the first PPDU carries a trigger frame. A second PPDU is sent over a second link. An end time of sending the second PPDU is not earlier than a first time and not later than a second time, the first time is related to an end time of sending the first PPDU and a state turnaround time, and the second time is related to the end time of sending the first PPDU and a short interframe space (SIFS) time.

Abstract: Embodiments of this application describe a communication method, a first station (STA), a second STA, and an access point (AP). One example method includes: setting, by a first station (STA), a basic service set (BSS) color to be used by a second STA in a device-to-device (D2D) transmission with the first STA, wherein the first STA sets the BSS color to be a first color that is preconfigured for D2D transmission, wherein the first color is different from a second color allocated by an access point (AP) associated with the first STA for transmission with the AP, and wherein the first color is used for D2D transmissions between the first STA and other STAs in addition to the first color being used for D2D transmission between the first STA and the second STA; generating, by the first STA, a data frame that comprises the BSS color that is the first color; and sending, by the first STA, the data frame to the second STA in the D2D transmission.

Abstract: This application provides a communication method and a multi-link device. The method includes: When only one of a plurality of links is successfully established, a first MLD performs air interface transmission with a second MLD according to a single-link communication rule. The plurality of links may be a plurality of links that the first MLD requests to establish, or the plurality of links may be a plurality of links that have been successfully established between the first MLD and the second MLD. According to the solution in this application, when only one of the plurality of links is successfully established, the first MLD does not perform air interface transmission with the second MLD according to a multi-link communication rule. Specifically, an address 2 field carried in a frame over the air that is sent by the first MLD is a MAC address of the first MLD.
