Embodiment 1

[0066] Embodiment 1 of the present application provides a wake-up frame transmission method, which is applied in a communication system. The communication system includes a sending station and a receiving station, wherein the receiving station includes a wake-up transceiver WUR and a main transceiver. This method can be applied to access points and stations such as: figure 2 AP and STA1-3 in. Figure 4 It is a flowchart of the method, and the specific steps are as follows:

[0067] Step 410: The sending station generates a response frame, where the response frame includes a response type field, and the response type field indicates the state of the sending station.

[0068] Step 420: the sending site sends the response frame.

[0069] It should be noted that, before the sending station generates the response frame, the method further includes:

[0070] The sending station sends a wake-up frame, the wake-up frame instructs the receiving station to turn on the main transceiv...

Embodiment approach 1

[0076] Embodiment 1: The response type field includes at least four types.

[0077] Wherein, the first type of information indicates that the sending station sends the wake-up frame, and the sending station has data to send to the receiving station.

[0078] The second type of information, the second type of information indicates that the sending station has not sent the wake-up frame, and the sending station has no data to send to the receiving station.

[0079] The third type of information, the third type of information indicates that the sending station sends the wake-up frame, and the sending station has no data to send to the receiving station.

[0080] Fourth type of information, the fourth type of information indicates that the sending station has not sent the wake-up frame, and the sending station has data to send to the receiving station.

[0081] It should be explained that the first type of information indicates that the sending station has successfully received t...

Embodiment approach 2

[0085] Embodiment 2: The response type field includes at least two types.

[0086] The fifth type of information, the fifth type of information indicates that the sending station has data to send to the receiving station.

[0087] Sixth type information, where the sixth type information indicates that the sending station has no data to send to the receiving station.

[0088] It should be explained that the fifth type of information indicates that the sending station has data to send to the receiving station. At this time, the receiving station should keep the main transceiver on, so as to receive the data to be sent by the sending station later.

[0089] It should be explained that the sixth type of information indicates that the sending station has no data to send to the receiving station. At this time, the receiving site can turn off the main transceiver to save energy.

Abstract

The invention provides a method for wakeup frame transmission, in the method, a sending station generates and sends a response frame, the response frame comprises a response type field, and the response type field indicates a state of the sending station. the invention also provides a corresponding device for wakeup frame transmission, through the method above, a receiving station learns the stateof the sending station, and the receiving station is facilitated to take different response strategies according to different states of the sending station.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a method and device for wake-up frame transmission. Background technique [0002] In IoT communication scenarios, network nodes are usually powered by batteries, which have very high requirements for low energy consumption. Energy consumption can be greatly reduced through the sleep mechanism, and the longer the sleep cycle, the better the energy saving effect. However, when the sleep cycle is too long, the transmission delay will be increased. If a system requires both low energy consumption and low latency, a contradiction arises. [0003] WLAN (English: Wireless Local Area Network, Chinese: Wireless Local Area Network) standard organization set up a new working group TG WUR (English: Task Group Wakeup Radio), the working group through WLAN equipment (including access point AP and station STA) A wake-up transceiver (abbreviation: WUR) is added to meet the re...
