    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.

    IPC: H04W52/02

    Abstract: Embodiments of the present invention disclose a state switching method and apparatus. The state switching method includes: receiving, by a first network node, a preset frame sent by a second network node, where the preset frame includes indication information used to indicate an on/off state of a main transceiver and/or a wake up receiver of the first network node immediately, after a specified time point, or within a specified time period; and controlling, by the first network node based on the indication information, to switch an on/off state of the main transceiver and/or the wake up receiver of the first network node. According to the embodiments of the present invention, energy is saved by using a preset frame to indicate an on/off state of a main transceiver and/or a wake up receiver of a network node after a specified time point or within a specified time period.

    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: Embodiments of the present invention provide an association establishment method and apparatus. The method includes: broadcasting, by an access point AP, a trigger frame, wherein the trigger frame is used to trigger one or more unassociated stations STAs to perform uplink data transmission and indicate one or more available subchannels for random accessing of the unassociated STAs; receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs; broadcasting, by the AP, a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message. In this way, the AP is associated with the unassociated stations STA, and communication reliability is ensured.

    Abstract: Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).
