WAKE-UP FRAME TRANSMITTING METHOD, AND METHOD, DEVICE AND EQUIPMENT FOR TRANSMITTING FIRST FRAME AFTER NODE WAKES UP

摘要

Embodiments of the present invention relate to the field of network technologies, and provide a method for sending a wake up packet, an apparatus, and a device. The method for sending a wake up packet is applied to a first node, a NAV of the first node is set on a first channel, and the method for sending a wake up packet includes: when detecting that a second channel is idle, ignoring, by a main transceiver of the first node, the NAV, and sending a wake up packet to a second node on the second channel. In the present invention, when the first channel on which a main transceiver of the second node works is different from the second channel on which a wake up receiver of the second node works, the first channel is listened to by default. When the NAV is set for the first node by using a frame on the first channel, but the second channel is idle, the first node can still send a wake up packet to the second node on the second channel, to wake up the main transceiver of the second node. This implements that the main transceiver of the second node can be woken up in time when the second channel is idle.
