Embodiment Construction

[0055] The present application can be applied to a wireless local area network (Wireless Local Area Networks, WLAN for short), and currently WLAN adopts the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE for short) 802.11 series. Wherein, a station (Station, STA for short) and an access point (Access Point, AP for short) are basic components of a WLAN.

[0056] Among them, AP is the access point for mobile users to enter the wired network. It is mainly deployed in homes, buildings, and campuses. The typical coverage radius is tens of meters to hundreds of meters. Of course, it can also be deployed outdoors. The AP is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together, and then connect the wireless network to the Ethernet. Specifically, the AP may be a terminal device or a network device with a WiFi (English: Wireless F...

Abstract

The present application provides a method and device for transmitting WUR control information. The method includes: the sending end device sends wake-up radio WUR control information to the main radio MR of the receiving end device, and the WUR control information includes: the physical layer parameters used when the sending end device sends the wake-up data packet WUP, the receiving At least one type of wake-up operation information of the MR of the end device; the sending end device sends the WUP to the wake-up receiver of the receiving end device according to the WUR control information. The method of the present application reduces the air interface overhead during WUP transmission, and greatly shortens the air interface time required for WUP transmission.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a method and device for transmitting control information of Wake up Radio (WUR for short). Background technique [0002] In a Wireless-Fidelity (WiFi for short) network, a considerable part of the energy of the receiving end device is wasted in idle listening when there is no received signal, that is, when the station (Station, STA for short) does not send and receive messages, if the Monitoring the channel will consume a lot of energy, so the sleep mechanism (SleepSchedule) is introduced in the communication standard so that the STA can enter the deep sleep (Deep Sleep) state when there is no data to send and receive, so as to reduce the energy consumption of continuous monitoring. However, when the STA is in deep sleep, the access point (Access Point, AP for short) cannot communicate with the STA, and the transmission between the two can only be performed after the ST...
