Abstract

The embodiment of the present application provides a method and device for transmitting a wake-up frame, the method includes: the first device determines the Enhanced Distributed Channel Access EDCA parameter set of the wake-up frame, and the wake-up frame is used to wake up one or more second The device receives the data frame; the first device determines whether the channel resource is in an idle state according to the EDCA parameter set of the wake-up frame; the first device sends the wake-up frame to the second device when the channel resource is in an idle state. In the embodiment of the present application, the first device can compete for channel resources according to the EDCA parameter set corresponding to the wake-up frame, so that the wake-up frame with high transmission priority can obtain high-priority service, thereby improving the QoS performance of the wake-up frame.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to methods and devices for transmitting wake-up frames. Background technique [0002] The Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11 standard organization plans to develop a new low-power (Lower Power, LP) wake-up receiver (Wake-up Receiver, WUR) in the receiving end device. After the main transceiver module of the receiver device goes to sleep, the low-power WUR wakes up and starts working. If the sending end device needs to communicate with the above receiving end device, the sending end device first sends a wake up packet to WUR, and WUR correctly receives the WUP sent to itself and then sends a wake up signal to the main transceiver module to wake up the receiving end device The main transceiver module of the device, so that the sending device can communicate with the main transceiver module...
